Imagecache Actions 7.x-1.5 2014-11-29
|
||||
-------------------------------------
|
||||
- [#2366163]: autorotate sometimes doesn't work with ImageMagick.
|
||||
- Text effect: small clean-up of hook_exit().
|
||||
- [#2379359]: image_imagemagick_overlay() passes a stream wrapper to convert.
|
||||
- [#2359523]: Overlay: allow to define offsets from all sides.
|
||||
- [#1717436]: Add effects: color level adjustment and desaturate while retaining
|
||||
alpha.
|
||||
- [#2278233]: Call to undefined function imagecache_actions_get_style_label().
|
||||
- [#2183721]: Duplicate/Export links just edit, they don't duplicate or export.
|
||||
possible solution only.
|
||||
- [#2176727]: New actions: scale / resize by percent.
|
||||
- [#2190759]: hook_image_style_flush(): Prefer silent failure over clear failure.
|
||||
- [#2166715]: Typo causes extra query every page load.
|
||||
- [#2139091]: # sign before HEX in settings form breaks Define canvas action.
|
||||
- [#2085967]: Remove .gitignore from version control.
|

||||
- [#2003446]: Clean up or remove .install files, adapt .info files.
|
||||
- [1854270-48]: Minor optimization for Posterize.
|
||||
- Refactor: eliminate test warnings and errors.
|
||||
- Refactor: standardize function and parameter naming, function order, doxygen
|

|
||||
|
||||
|
||||
Imagecache Actions 7.x-1.4 2013-08-24
|
||||
-------------------------------------
|
||||
- [#1778214]: Remove project from image_effects_text_test.info
|
||||
- [#1854270]: Posterize action for file size/bandwidth saving on PNGs.
|
||||
- [#2060173]: Support image labels (introduced by D7.23).
|
||||
- Cleaned up the output of image style export. Id's and help texts are not used
|
||||
on import, so don't have to be exported.
|
||||
- Repaired farbtastic colorpicker. It seems the library invocation changed
|
||||
sometime in history. Rebuilt the color picker form to use #attached libraries
|
||||
and simpler inline script instead. REMOVED the theme function that is now
|
||||
redundant as #attached is a better way than drupal_add_js.
|
||||
- [#1152736]: Support tokens in text actions for images.
|
||||
- [#2025631]: Imagecache Testsuite refers to non-existent permissions.

||||
|
||||
|
||||

|
||||
- [#2010560]: Fix spelling for "Update 7001".
|
||||
|
||||
|
||||
Imagecache Actions 7.x-1.2 2013-06-01
|
||||
-------------------------------------
|
||||

||||
- [#1446160]: Integrate with media module: Title and Alt text.
|
||||
- [#1591198]: Have dimensions calculations not ignore NULL's.
|
||||
- Refactored canvas effects: added parameter types in documentation and
|
||||
signatures. Standardized function documentation. Comments according to Drupal
|
||||
coding standards.
|
||||
- [#1999140]: Canvas effects using imagemagick might fail due to earlier
|
||||
-gravity settings.
|
||||
- Refactored the image_effects_text_test module to no longer depend on features.
|
||||
- [#1998354]: Non-ASCII characters fail to display correctly on many systems
|
||||
(when using Imagemagick).
|
||||
- Further code enhancements (messages, comments) to autorotate.
|
||||
- [#1930728]: Autorotate does not reset EXIF orientation tag.
|
||||
- [#1990620] Many config form docs missing from the D7 upgrade. Converted all
|
||||
legacy instances of #type=markup into #markup='content..'
|
||||
- Removed deprecated functions imagecache_actions_entities_from_references() and
|
||||
imagecache_actions_fields_from_filepath() (see [#1844298]).
|
||||
- [#1983168]: Custom text via PHP causing EntityMalformedException ...
|
||||
- Replaced lhandw.ttf font with some real free fonts that may also be
|
||||
distributed for free. Changed all text effect tests accordingly.
|
||||
- Better text effect defaults (translated sample text, text visible by default,
|
||||
sample font file).
|
||||
- [#1986304]: Strict warning: Only variables should be passed by reference ...
|
||||
- [#1981490]: Wrong filename imagecache_Actions.install.
|
||||
- [#1858760]: Unable to find the file 'lhandw.ttf'. Please check the path.
|
||||
|
||||
|
||||
Imagecache Actions 7.x-1.1 2012-12-04
|
||||
-------------------------------------
|
||||
- [#1591198]: Image dimensions callbacks should handle unknown (NULL) dimensions
|
||||
as valid input.
|
||||
- [#464092]: Aspect Switcher -- Need to Flush Presets. Side-effect: now allows
|
||||
to define no image style for either landscape or portrait.
|
||||
- [#1676924]: Autorotate: check for exif extension and test dimensions callback.
|
||||
- [#1849020]: Cant get text test examples to work.
|
||||
- [#1702716]: System Stream Wrappers Conflict.
|
||||
- [#1844298]: Remove dependency from entity module.
|
||||
- [#1778594]: Negative image effect does not work.
|
||||
- [#1778214]: Remove version from image_effects_text_test.info.
|
||||
- [#1752664]: Error on importing image style.
|
||||
- [#1676924]: Autorotate: check for exif extension.
|
||||
- [#1666912] by Dubs: Call to undefined function.
|
||||
imagecache_actions_get_image_context() in imagecache_customactions.module.
|
||||
- [#1630194]: Custom actions broken after upgrading from dev to prod.
|
||||
- [#1591484] by epieddy: Underlay Center or Right parameter not working.
|
||||
- Moved the image styles administrative features to its own module.
|
||||
- Augment the duplicate with an export and import. This will allow users to
|
||||
duplicate between sites or to post failing styles in the issue queue (without
|
||||
using the features module).
|
||||
- Backport of patch from geoffreyr for [#1403962]: Add action "duplicate" to
|
||||
image style admin screen. This will allow us to easily create large sets of
|
||||
test/showcase styles and to fine tune this request before it lands in D8 core.
|
||||
|
||||
|
||||
Imagecache Actions 7.x-1.0 2012-05-19
|
||||
-------------------------------------
|
||||
Incompatibilities:
|
||||
- Effects that operate on the transparency layer, do not automatically change
|
||||
the format anymore to png. You will have to add this as a separate effect.
|
||||
- File handling: the way that files (e.g. fonts, watermarks, backgrounds) are
|
||||
searched for has been aligned over all effects that work with an additional
|
||||
file. This may cause current styles to not being able to find specified files
|
||||
anymore.
|
||||
- Custom actions: custom snippets are now executed using the PHP filter module,
|
||||
meaning that the image style editor must have the 'Use PHP for settings'
|
||||
permission to be able to edit the custom action snippet.
|
||||
- Custom actions: information and variables that are available in your custom
|
||||
snippet have changed. See the README.txt of the custom actions module.
|
||||
|
||||
No changelog exists from before this 7.x-1.0 version. So the changelog starts
|
||||
from here. 7.x-1.0 is the first reasonably well working D7 version. The 7.x-0.0
|
||||
version was based on posted patches in the D7 port request issue and has never
|
||||
been tested well. This 7.x-1.0 version is also not extensively tested by the
|
||||
maintainers, but has been used in many (live) sites - currently (may 2012) over
|
||||
5.000 reported 7.x-1.x-dev installs - so has received fairly good "test
|
||||
coverage".

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Lesser General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|

to distribute software through any other system and a licensee cannot
|

impose that choice.
|

This section is intended to make thoroughly clear what is believed to
|

be a consequence of the rest of this License.
|

|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.

NO WARRANTY
|

END OF TERMS AND CONDITIONS
|

How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||

(at your option) any later version.
|
||||

|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of

|
||||
|
||||
You should have received a copy of the GNU General Public License along
|
||||
with this program; if not, write to the Free Software Foundation, Inc.,
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|

under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:

Release notes for 7.x-1.x-dev
|
||||
-----------------------------
|
||||
- Clear all caches after updating.
|
||||
|
||||
|
||||
Release notes for 7.x-1.4
|
||||
-------------------------
|
||||
- This release supports image labels as introduced by Drupal 7.23.
|
||||
- See CHANGELOG.txt for a full overview of changes.
|
||||
|
||||
|
||||
Release notes for 7.x-1.1
|
||||
-------------------------
|
||||
- If you use the module:// notation anywhere in an image effect, you must now
|
||||
install the System Stream Wrapper module
|
||||
(https://drupal.org/project/system_stream_wrapper).
|
||||
- Clear the cache after updating.
|
||||
|
||||
|
||||
Release notes for 7.x-1.0
|
||||
-------------------------
|
||||
- Clear the (registry) cache after installing or updating to 7.x-1.0.
|
||||
- If you use custom actions, run update.php.
|
||||
- If you use custom actions, be sure to enable the 'PHP filter' module and give
|
||||
image style editors that may create custom actions the 'use PHP for settings'
|
||||
permission. The module must also be enabled on image creation.
|
||||
- If you use custom actions, please read the README.txt from that sub-module to
|
||||
find out about how information and resources are available to you. You will
|
||||
probably have to change your code snippets.
|
||||
- If you use effects that use files (mask, overlays, underlays, text fonts),
|
||||
check the way they are specified. From 7.x-1.0 on, you have to specify the
|
||||
location using one of the schemes private://, public://, module:// or
|
||||
temporary://. If no scheme is specified, the file is searched for as is, thus
|
||||
relative to the current directory or as an absolute path.
|
||||
- Effects that use the transparency layer (e.g. mask, rounded corners) do not
|
||||
automatically convert to PNG anymore. Use the "Change file format" for that.
|
||||
- There's no upgrade from D6. You will have to recreate your styles manually.
|
||||
|
||||
Warning:
|
||||
Ongoing development in the area of e.g. making the effects more consistent,
|
||||
adding and/or removing parameters or redefining their meaning, might cause
|
||||
backward incompatibilities between future versions and the current version.
|
||||
Thus, we cannot and do not guarantee backwards compatibility or automatic
|
||||
upgrade paths for future versions.
|
||||
|
||||
|
||||
Introduction
|
||||
------------
|
||||
The Imagecache Actions module provides a suite of additional image effects that
|
||||
can be added to image styles. Image styles let you create derivations of images
|
||||
by applying (a series of) effect(s) to it. Think of resizing, desaturating,
|
||||
masking, etc.
|
||||
|
||||
Furthermore, imagecache_actions extends the administrative interface for image
|
||||
styles by providing additional features. It does so in the "Image styles admin"
|
||||
sub module.
|
||||
|
||||
The additional effects that Imagecache Actions provides include:
|
||||
- Watermark: place a image with transparency anywhere over a source picture.
|
||||
- Overlay: add photo-corners etc to the image
|
||||
- Text overlay: add e.g. a copyright notice to your image.
|
||||
- Color-shifting: colorize images.
|
||||
- Brighten/Darken.
|
||||
- Alpha blending: use a gray scale image to define the transparency layer of an
|
||||
image.
|
||||
- Canvas manipulation: resize the canvas and add a background color or image.
|
||||
- File Format switcher: if you need transparency in JPGs, make them PNG. If your
|
||||
PNG thumbnails are 30K each, save them as JPGs.
|
||||
- Rounded corners.
|
||||
- TODO: complete list, check short descriptions
|
||||
|
||||
These effects are grouped in sub-modules. Just enable the ones you want to use.
|
||||
TODO: list sub-modules and their sets of effects.
|
||||
|
||||
Imagecache Actions supports both the GD toolkit from Drupal core and the
|
||||
Imagemagick toolkit. However, please note that Imagemagick support is not yet
|
||||
complete. Please file an issue if you encounter problems in using Imagemagick.
|
||||
|
||||
|
||||
What is imagecache_action not?
|
||||
------------------------------
|
||||
Imagecache Actions does not provide a new UI or new menu items. It hooks into
|
||||
the already existing image styles system (from Drupal core). See
|
||||
https://drupal.org/documentation/modules/image for more information about
|
||||
working with images.
|
||||
|
||||
|
||||
A note about the name of this module
|
||||
------------------------------------
|
||||
Image styles are part of Drupal 7 core and are the successor of the Drupal 6
|
||||
imagecache module. In Drupal 6 image styles were called (imagecache) presets and
|
||||
the separate effects that made up a style were called (imagecache) actions. In
|
||||
porting to D7, that name has not been changed (yet).
|
||||
|
||||
|
||||
Which toolkit to use?
|
||||
---------------------
|
||||
Personally, I (fietserwin) prefer the imagemagick toolkit:
|
||||
- It is better in anti-aliasing. Try to rotate an image using both toolkits and
|
||||
you will see what I mean.
|
||||
- It does not execute in the PHP memory space, so is not restricted by the
|
||||
memory_limit PHP setting.
|
||||
- The GD toolkit will, at least on my Windows configuration, keep the font file
|
||||
open after a text operation, so you cannot delete, move or rename it anymore.
|
||||
|
||||
On the other hand: the GD toolkit is always available (in the correct version),
|
||||
whereas imagemagick is not always present on shared hosting or may be present in
|
||||
an antique version that might give problems.
|
||||
|
||||
Please note that effects may give different results depending on the
|
||||
toolkit used.
|
||||
|
||||
Please also note that a 3rd image toolkit exists:
|
||||
Imagick (https://www.drupal.org/project/imagick)
|
||||
This toolkit uses the Imagick extension and thus does not call the ImageMagick
|
||||
binaries directly. However our module does not implement the toolkit specific
|
||||
parts for the effects we provide for the Imagick toolkit, but the Imagick
|
||||
toolkit comes with its own set of effects that partly covers our effects. So,
|
||||
depending on the effects you require it may be a replacement for both our module
|
||||
and the Imagemagick module or the core GD toolkit.
|
||||
|
||||
Hard Dependencies
|
||||
-----------------
|
||||
- Image module from Drupal core
|
||||
|
||||
At least 1 of the available image toolkits:
|
||||
- GD toolkit from Drupal core.
|
||||
- Imagemagick toolkit: https://drupal.org/project/imagemagick.
|
||||
|
||||
|
||||
Soft Dependencies
|
||||
-----------------
|
||||
- System stream wrapper (https://drupal.org/project/system_stream_wrapper)
|
||||
- Remote stream wrapper (https://drupal.org/project/remote_stream_wrapper)
|
||||
These modules provide additional stream wrappers. Especially the system stream
|
||||
wrapper is very handy as it provides, among others, a module:// and theme://
|
||||
wrapper.
|
||||
|
||||
|
||||
Installing
|
||||
----------
|
||||
As usual.
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
After enabling the module:
|
||||
- Assure that the Image module from core is enabled.
|
||||
- Configure your toolkit and its settings at admin/config/media/image-toolkit.
|
||||
- Define image styles at admin/config/media/image-styles and add 1 or more
|
||||
effects as defined by this module
|
||||
- Use the image styles via e.g. the formatters of image fields.
|
||||
|
||||
|
||||
Upgrading from D6
|
||||
-----------------
|
||||
There's no upgrade path defined for sites upgrading from D6 to D7. This means
|
||||
that you will have to manually redefine your D6 imagecache presets as D7 image
|
||||
styles. Note that actually an upgrade path would have to be defined by the
|
||||
imagecache module, not this imagecache actions module. However, as there is no
|
||||
D7 version of imagecache that provides an upgrade, users may post an upgrade
|
||||
function to the issue queue and we will incorporate it.
|
||||
|
||||
|
||||
Backwards compatibility
|
||||
-----------------------
|
||||
Future releases will not be guaranteed to be backwards compatible. Implementing
|
||||
Imagemagick support e.g. might give unforeseen problems that can only be solved
|
||||
by changing the details of what an effect does. We will document these kind of
|
||||
incompatibilities in the changelog and the release notes.
|
||||
|
||||
|
||||
File form fields
|
||||
----------------
|
||||
A number of effects have a file form field where the editor can define a file
|
||||
name to use. This can be e.g. for overlays, masks or fonts. The file name should
|
||||
be defined using either:
|
||||
- 1 of the (enabled) scheme's:
|
||||
* public://
|
||||
* private:// Preferred for site specific masks, overlays, etc, that do not
|
||||
need to be shared publicly.
|
||||
* temporary:// Unlikely to be useful, but supported anyway as all schemes are
|
||||
supported.
|
||||
* module:// Introduced by the system stream wrapper module and preferred for
|
||||
module provided resources.
|
||||
* theme:// idem.
|
||||
* profile:// idem.
|
||||
* library:// idem.
|
||||
- A relative (to the current directory, probably Drupal root) or absolute path.
|
||||
|
||||
|
||||

||||
Via the issue queue of this project at Drupal.org.

Known problems
|
||||
--------------
|
||||
These are better documented in the issue queue, but might be listed here (as
|
||||
well).
|
||||
|
||||
- Underlay does not work in imagemagick if the dimensions of both images are not
|
||||
equal. As a workaround first add a canvas effect with a fully transparent
|
||||
background.
|
||||
- Underlay/overlay: keywords in the x and y offset fields do not work.
|
||||
- Underlay does still display a message about Imagemagick not being supported.
|
||||
- Brightness values outside the -250 .. 250 range are accepted.
|
||||
- Check color fields that allow a transparency component or allow to be empty to
|
||||
specify fully transparent.
|
||||
|
||||
Known problems: Imagemagick
|
||||
---------------------------
|
||||
- Define canvas using offsets may bot work on older versions. We have an error
|

Imagecache Actions roadmap
|
||||
--------------------------
|
||||
|
||||
This is a non-contractual roadmap for the D7 branch of the imagecache actions
|
||||
module. Actual release dates and completed features will largely depend on
|
||||
available time. So support is always welcome. Furthermore, critical bugs may
|
||||
make us release more often, but that should only change the release number in
|
||||
which certain features are planned, not the timeline.

which toolkit (version).
|
||||
- (ALMOST DONE) Check that all effects implement all of the effects API (especially the
|
||||
dimensions callback).
|
||||
- Add testing. The idea is to create a set of image styles that cover all
|
||||
effects and can be used to visually check for regressions.
|
||||
|
||||
Automated testing would be nice, but I am not sure that we can guarantee that
|
||||
jpeg or png files are binary identical on each run across different computers.
|
||||
But if the number of false positives is small, it would certainly be a useful

addition.

README
|
||||
------
|
||||
README for the custom actions effect module.
|
||||
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
Hard dependencies:
|
||||
- Imagecache actions.
|
||||
- Image (Drupal core).
|
||||
|
||||
Soft dependencies/recommended modules:
|
||||
- Imagemagick (preferred toolkit).
|
||||
- PHP filter (Drupal core).
|
||||
|
||||
|
||||
Which toolkit?
|
||||
--------------
|
||||
Personally, I prefer the imagemagick toolkit:
|
||||
- It is better in anti-aliasing, try to rotate an image using both toolkits and
|
||||
you will see what I mean.
|
||||
- It does not execute in the PHP memory space, so is not restricted by the
|
||||
memory_limit PHP setting.
|
||||
- The GD toolkit will, at least on my Windows configuration, keep font files
|
||||
open after a text operation, so you cannot delete, move or rename it anymore.
|
||||
|
||||
|
||||
Installing
|
||||
----------
|
||||
As usual. After enabling the module you can add custom actions to images.
|
||||
|
||||
|
||||
Custom action PHP snippets
|
||||
--------------------------
|
||||
Given the correct permission, the custom action effect allows you to write your
|
||||
own PHP snippet that does the requested processing on the image. How it can do
|
||||
so, depends on the toolkit.
|
||||
|
||||
For all toolkits, the snippet should return true to indicate success and false
|
||||
to indicate failure.
|
||||
|
||||
GD
|
||||
--
|
||||
The GD image resource is available in $image->resource. You can call the GD
|
||||
functions on this resource. This effect will query the width and height after
|
||||
your processing, so you don't have to change that yourself.
|
||||
|
||||
Imagemagick
|
||||
-----------
|
||||
All real image processing is done at the end, if all effects have added their
|
||||
command line arguments to the $image->ops array. So your custom action should
|
||||
add the imagemagick commands and its parameters by adding new string entries to
|
||||
the end of that array.
|
||||
|
||||
If your commands change the width or height of the resulting image, you should
|
||||
record so by changing $image->info['width'] and/or $image->info['height'].
|
||||
|
||||
General
|
||||
-------
|
||||
To ease your task, this effect makes some information regarding the image being
|
||||
processed available in 2 variables: $image and $image_context. These variables
|
||||
are readily available in your snippet.
|
||||
|
||||
$image is an object containing the following properties:
|
||||
- source: string, the source of the image, e.g. public://photo.jpg
|
||||
- info: array, example data:
|
||||
- width (int) 180
|
||||
- height (int) 180
|
||||
- extension (string) png
|
||||
- mime_type (string) image/png
|
||||
- file_size (int) 4417
|
||||
- toolkit: string, imagemagick or GD
|
||||
- resource: resource. The GD image resource.
|
||||
- ops: array. An array of strings with the ImageMagick commands.
|
||||
|
||||
$image_context is an associative array containing:
|
||||
- effect_data: array, the data of this image effect, example data for the custom
|
||||
action effect:
|
||||
- php (string)
|
||||
- managed_file: object|null. A managed file object containing these properties:
|
||||
- fid (string) 2
|
||||
- uid (string) 1
|
||||
- filename (string) photo.jpg
|
||||
- uri (string) public://photo.jpg
|
||||
- filemime (string) image/jpeg
|
||||
- filesize (string) 445751
|
||||
- status (string) 1
|
||||
- timestamp (string) 1327525851
|
||||
- metatags Array [0]
|
||||
- rdf_mapping Array [0]
|
||||
- referring_entities: array|null. A nested array with (fully loaded) entities
|
||||
referring to the current image. The 1st level of entries is keyed by the field
|
||||
name, the 2nd by entity type, and the 3rd by entity id. Example data:
|
||||
- field_photo Array [1]
|
||||
- node Array [1]
|
||||
- 12 Object of: stdClass
|
||||
- nid (string) 12
|
||||
- vid (string) 12
|
||||
- type (string) page
|
||||
- author ...
|
||||
- timestamp ...
|
||||
- ...
|
||||
- entity: object|null, the 1st entity in referring_entities. This is for easy
|
||||
access to the referring entity if it may be assumed that only 1 entity is
|
||||
referring to the current image.
|
||||
- image_field: array|null, the 1st image field in entity that is referring to
|
||||
the current image. This is for easy access to the image field data if it may
|
||||
be assumed that only 1 image field is referring to the current image. Example
|
||||
data:
|
||||
- fid (int) 2
|
||||
- alt (string) ...
|
||||
- title (string) ...
|
||||
- ...
|
||||
|
||||
Of course there are many other possible useful globals. Think of:
|
||||
- base_url
|
||||
- base_path
|
||||
- base_root
|
||||
- is_https
|
||||
- user
|
||||
- language
|
||||
and of course $_SERVER and $_GET.
|
||||
|
||||
Using these information you can access entity data as follows:
|
||||
|
||||
Specific case (1 entity, of known entity_type, referring to the image):
|
||||
<?php
|
||||
$entity_type = 'node';
|
||||
$field_name = 'my_field';
|
||||
$entity = $image_context['entity'];
|
||||
$field = field_get_items($entity_type, $entity, $field_name);
|
||||
?>
|
||||
|
||||
Or the more general case (not knowing the referring type, or multiple entities
|
||||
that may be referring to the image):
|
||||
<?php
|
||||
$referring_entities = $image_context['referring_entities'];
|
||||
foreach ($referring_entities as $field_name => $field_referring_entities) {
|
||||
foreach ($field_referring_entities as $entity_type => $entities) {
|
||||
foreach ($entities as $entity_id => $entity) {
|
||||
$field = field_get_items($entity_type, $entity, $field_name);
|
||||
}
|
||||
}
|
||||
}
|
||||
?>

Aspect Switcher

<h3>
|
||||
Using aspect switcher to create a 'square' setting.
|
||||
</h3>
|
||||
<p>
|
||||
This is done through "chaining" two switches - "is it quite
|
||||
wide or not?", then "is it quite tall or not?" which leaves
|
||||
us with "must be square then."
|
||||
</p>
|
||||
<p>
|
||||
First we create the three sizes we will be using,
|
||||
small-landscape, small-square, small-portrait. I'll just set
|
||||
those up with scale_and_crop.
|
||||
</p>
|
||||
<p>
|
||||
We want wide images up to a ratio of 1:0.75 to be rendered
|
||||
wide. We want squarish images, with an aspect between 1:0.75
|
||||
and 1:1.25 to be rendered square, and anything taller to be
|
||||
rendered tall.
|
||||
</p>
|
||||
<p>
|
||||
To do this, we chain 2 rules. We need to build them
|
||||
backwards, the smaller sub-rule first, but to understand, I'l
|
||||
list them top down.
|
||||
</p>
|
||||
<p>
|
||||
Rule 1. is the master rule, <strong>3-aspects</strong>
|
||||
</p>
|
||||
<p>
|
||||
if ratio is less than 1:.75, use small-landscape. If greater,
|
||||
<strong>proceed to rule 2</strong>.
|
||||
</p>
|
||||
<p>
|
||||
</p>
|
||||
<p>
|
||||
Rule 2. <strong>square-or-portrait</strong>
|
||||
</p>
|
||||
<p>
|
||||
if ratio is less than 1:1.25, use small-square. If greater,
|
||||
use small-portrait.
|
||||
</p>
|
||||
<p>
|
||||
To do this, we use the aspect switcher to link to the two
|
||||
sizes, and the <em>ratio adjustment</em> to move
|
||||
the switching point a little. Set the ratio adjustment to
|
||||
1.25
|
||||
</p>
|
||||
<p>
|
||||
With these (5!) rules in place, you can get the desired
|
||||
effect. This is a little trickier than just making a 'square'
|
||||
setting, but it allows for the required fudge factor to
|
||||
handle almost-square images.
|
||||
</p>
|
||||
<p>
|
||||
You can nudge the adjustment factor to be looser or tighter.
|
||||
You can create even more chained rules, and define a
|
||||
'super-wide' size.

||||

The illustration shows the result of this set-up on a
|
||||
collection of images. The listed dimensions are those of the
|
||||
source images. You'll see that the mostly-square ones are
|
||||
rendered square.
|
||||
</p>
|
||||
<img src="../docs/aspect-chaining.png" alt="Illustration of several different sized images passing through the above ruleset."/>
|
||||
<p>
|
||||
The rule being applied is: 1 Is it wide?
|
||||
</p>
|
||||
<p>
|
||||
For image 250x300, the aspect is ( 250/300 = 0.83 ) Normally
|
||||
that number (less than 1) would be classified as 'portrait',
|
||||
and with the adjustment (*0.75) that is still true, so the
|
||||
processing passes through to the portrait preset.
|
||||
</p>
|
||||
<p>
|
||||
rule #2 it it tall?
|
||||
</p>
|
||||
<p>
|
||||
This preset however does a different set of maths, and
|
||||
multiplies the aspect by 1.25, producing a result that causes
|
||||
it to trigger to 'landscape' choice. 'landscape' at this
|
||||
point is set to be the 'square' preset. And we get what we
|
||||
wanted.

README
|
||||
------
|
||||
README for the Image effect text module.
|
||||
|
||||
Author Erwin Derksen (fietserwin: https://drupal.org/user/750928)
|
||||
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
Hard dependencies:
|
||||
- Imagecache actions.
|
||||
- Image (Drupal core).
|
||||
|
||||
Soft dependencies/recommended modules:
|
||||
- Imagemagick (preferred toolkit, https://drupal.org/project/imagemagick).
|
||||
- PHP filter (Drupal core, if yuo want to use PHP to create the text to render).
|
||||
- System stream wrapper (https://drupal.org/project/system_stream_wrapper)
|
||||
- Remote stream wrapper (https://drupal.org/project/remote_stream_wrapper)
|
||||
The latter 2 provide additional stream wrappers. Especially the system stream
|
||||
wrapper is very handy as it provides, among others, a module:// and theme://
|
||||
wrapper.
|
||||
|
||||
|
||||
Toolkit
|
||||
-------
|
||||
Personally, I prefer the imagemagick toolkit:
|
||||
- It is better in anti-aliasing, try to rotate an image using both toolkits and
|
||||
you will see what I mean.
|
||||
- It does not execute in the PHP memory space, so is not restricted by the
|
||||
memory_limit PHP setting.
|
||||
- The GD toolkit will, at least on my Windows configuration, keep the font file
|
||||
open after a text operation, so you cannot delete, move or rename it anymore.
|
||||
- This module does a better job with Imagemagick (see below).
|
||||
|
||||
|
||||
Installing
|
||||
----------
|
||||
As usual. After enabling the module you can add texts to images. This image
|
||||
effect works with both the GD and imagemagick toolkit, though results differ
|
||||
depending on the toolkit you use.
|
||||
|
||||
|
||||
More information about the effect data options
|
||||
----------------------------------------------
|
||||
|
||||
Font
|
||||
----
|
||||
This module comes with some free fonts so you can easily test this effect.
|
||||
Please read their respective licences.
|
||||
|
||||
For real use, you normally want to use your own font as dictated by the website
|
||||
design. The font types supported depend on the toolkit in use, but at least ttf
|
||||
files will always work. This option accepts either:
|
||||
- 1 of the (enabled) scheme's:
|
||||
* public://
|
||||
* private:// Preferred for site specific masks, overlays, etc, that do not
|
||||
need to be shared publicly.
|
||||
* temporary:// Unlikely to be useful, but supported anyway as all schemes are
|
||||
supported.
|
||||
* module:// Introduced by the system stream wrapper module and preferred for
|
||||
module provided resources.
|
||||
* theme:// idem.
|
||||
* profile:// idem.
|
||||
* library:// idem.
|
||||
- A relative path (relative to the current directory, probably Drupal root).
|
||||
- An absolute path.
|
||||
- A system or toolkit font specification. E.g. on my Windows system 'arial.ttf'
|
||||
worked with both GD and Imagemagick. A warning will be issued but that may be
|
||||
ignored when it works as expected.
|
||||
|
||||
|
||||
Text position
|
||||
-------------
|
||||
The text position defines the point in the image where you want to place (align)
|
||||
your text. It starts at the top left corner of the image with position 0,0 and
|
||||
the positive directions are to the right and down.
|
||||
|
||||
The definition of the vertical position differs per toolkit. For GD it is the
|
||||
position of the font baseline, while for Imagemagick it is the bottom of the
|
||||
bounding box, i.e the descender or beard line in typography terminology.
|
||||
|
||||
|
||||
Text alignment
|
||||
--------------
|
||||
You can align your text with regard to the text position. Possible horizontal
|
||||
alignments are left (default), center and right. Vertical alignments are top,
|
||||
center and bottom (default).
|
||||
|
||||
Note: Given
|
||||
- the way that GD uses the vertical text position (as baseline),
|
||||
- and the way this module implements (vertical) alignment (translating the
|
||||
(vertical) position using the calculated bounding box),
|
||||
vertical alignment with the GD toolkit is a bit off. You will have to compensate
|
||||
for this yourself.
|
||||
|
||||
|
||||
Rotation
|
||||
--------
|
||||
The text can be rotated before being overlaid on the image. The value is in
|
||||
degrees. Positive values are rotated clockwise, So 90 degrees is straight down.
|
||||
negative values counter clockwise.
|
||||
|
||||
In Imagemagick the text is rotated around the text position. Thus centered text
|
||||
is rotated around its own center. GD, on the other hand, always rotates around
|
||||
the left bottom (baseline) position, regardless the text alignment. So using
|
||||
rotation with a non default alignment (left bottom) will give surprising
|
||||
results.
|
||||
|
||||
|
||||
Text source
|
||||
-----------
|
||||
The text to place on the image may come from different sources:
|
||||
- Text (with token replacement): the text to place on the image has to be
|
||||
entered on the image effect form. Use this e.g. for a copyright notice.
|
||||
notes:
|
||||
* Token replacement: you can use all global tokens, the file tokens, and
|
||||
tokens from entities referring to the image via an image field. Example: if
|
||||
you know that the image style is only used for article nodes, you can use
|
||||
[node:field-image:alt] to get the alt text of the image. Note: this specific
|
||||
example requires the entity_token module.
|
||||
* New lines: you can add a new line by adding \n to your text. To get a
|
||||
literal \n, use \\n.
|
||||
- PHP: the text to place on the image comes from a piece of PHP code that should
|
||||
return the text to place on the image. Only users with the 'use PHP for
|
||||
settings' permission are allowed to use this source. This permission and the
|
||||
evaluation of the PHP code come from the PHP filter module which is part of
|
||||
Drupal core and thus needs to be enabled, also during image generation.
|
||||
To add new lines to your text add them literally to the string you return,
|
||||
normally by using "\n" in your PHP code.
|
||||
- Image Alt or Title: to alleviate the need to enable the PHP filter module, 2
|
||||
commonly used sources for dynamic texts are directly available without any
|
||||
coding: the alt and title properties of an image field linked to the image at
|
||||
hand.
|
||||
|
||||
Notes:
|
||||
- When using token replacement or the image alt or title, multiple image fields,
|
||||
possibly in different languages, may be referring to the image that is being
|
||||
processed. This module will take the first image field it finds to extract the
|
||||
alt and title. If the field in itself is multi-lingual, thus not a synced
|
||||
field, the current language will be taken, which is the language of the user
|
||||
that happens to request this image derivative first.
|
||||
- This module will not automatically break text based on available space.
|
||||
- Due to the way that GD text box positioning works it is quite difficult to
|
||||
correctly position multiple lines of text with GD. If you have a working
|
||||
solution please post a patch. (Probably involves exploding the text in
|
||||
separate lines and then positioning each line separately.)
|
||||
|
||||
|
||||
PHP snippets to determine the text
|
||||
----------------------------------
|
||||
Given the correct permission, you can write your own PHP snippet to compute the
|
||||
text to display. To ease this task, this module makes some information regarding
|
||||
the image being processed available in 2 variables: $image and $image_context.
|
||||
These variables are readily available in your snippet.
|
||||
|
||||
$image is an object containing the following properties:
|
||||
- source: string, the source of the image, e.g. public://photo.jpg
|
||||
- info: array, example data:
|
||||
- width (int) 180
|
||||
- height (int) 180
|
||||
- extension (string) png
|
||||
- mime_type (string) image/png
|
||||
- file_size (int) 4417
|
||||
- toolkit: string, imagemagick or GD
|
||||
|
||||
$image_context is an associative array containing:
|
||||
- effect_data: array, the data of this image effect, example data for the text
|
||||
effect:
|
||||
- size (string) 12
|
||||
- xpos (string) center
|
||||
- ypos (string) center
|
||||
- halign (string) left
|
||||
- valign (string) bottom
|
||||
- RGB Array [1]
|
||||
- HEX (string) 000000
|
||||
- alpha (string) 100
|
||||
- angle (string) 0
|
||||
- fontfile (string:46) module://image_effects_text/Komika_display.ttf
|
||||
- text_source (string) text
|
||||
- text (string) Hello World!
|
||||
- php (string) return 'Hello World!'
|
||||
- managed_file: object|null. A managed file object containing these properties:
|
||||
- fid (string) 2
|
||||
- uid (string) 1
|
||||
- filename (string) photo.jpg
|
||||
- uri (string) public://photo.jpg
|
||||
- filemime (string) image/jpeg
|
||||
- filesize (string) 445751
|
||||
- status (string) 1
|
||||
- timestamp (string) 1327525851
|
||||
- metatags Array [0]
|
||||
- rdf_mapping Array [0]
|
||||
- referring_entities: array|null. A nested array with (fully loaded) entities
|
||||
referring to the current image. The 1st level of entries is keyed by the field
|
||||
name, the 2nd by entity type, and the 3rd by entity id. Example data:
|
||||
- field_photo Array [1]
|
||||
- node Array [1]
|
||||
- 12 Object of: stdClass
|
||||
- nid (string) 12
|
||||
- vid (string) 12
|
||||
- type (string) page
|
||||
- author ...
|
||||
- timestamp ...
|
||||
- ...
|
||||
- entity: object|null, the 1st entity in referring_entities. This is for easy
|
||||
access to the referring entity if it may be assumed that only 1 entity is
|
||||
referring to the current image.
|
||||
- image_field: array|null, the 1st image field in entity that is referring to
|
||||
the current image. This is for easy access to the image field data if it may
|
||||
be assumed that only 1 image field is referring to the current image. Example
|
||||
data:
|
||||
- fid (int) 2
|
||||
- alt (string) ...
|
||||
- title (string) ...
|
||||
- ...
|
||||
|
||||
Of course there are many other possible useful globals. Think of:
|
||||
- base_url
|
||||
- base_path
|
||||
- base_root
|
||||
- is_https
|
||||
- user
|
||||
- language
|
||||
and of course $_SERVER and $_GET.
|
||||
|
||||
Using these information you can access entity data as follows:
|
||||
|
||||
Specific case (1 entity, of known entity_type, referring to the image):
|
||||
<?php
|
||||
if (!$image_context['entity']) {
|
||||
return 'No referring entity';
|
||||
}
|
||||
$entity_type = 'node';
|
||||
$field_name = 'my_field';
|
||||
$entity = $image_context['entity'];
|
||||
$field = field_get_items($entity_type, $entity, $field_name);
|
||||
if ($field) {
|
||||
return isset($field[0]['value']) ? $field[0]['value'] : 'No field value';
|
||||
}
|
||||
?>
|
||||
|
||||
Or the more general case (not knowing the referring type, or multiple entities
|
||||
that may be referring to the image):
|
||||
<?php
|
||||
if (!$image_context['referring_entities']) {
|
||||
return 'No referring entities';
|
||||
}
|
||||
$referring_entities = $image_context['referring_entities'];
|
||||
foreach ($referring_entities as $field_name => $field_referring_entities) {
|
||||
foreach ($field_referring_entities as $entity_type => $entities) {
|
||||
foreach ($entities as $entity_id => $entity) {
|
||||
$field = field_get_items($entity_type, $entity, $field_name);
|
||||
// ...
|
||||
}
|
||||
}
|
||||
}
|
||||
?>
|
||||
|
||||
TODO
|
||||
----
|
||||
- Vertical alignment: add baseline as vertical alignment and make both toolkits
|
||||
behave the same for any given vertical alignment.
|
||||
- Rotation and alignment. Imagemagick seems to be more correct. Can GD made to
|
||||
do the same?
|
||||
- Language and alt/title: what if the first user to pass by and that generates
|
||||
the image is in a language that has no alt/title?
|
||||
- Check for existence of imagettftext() and fail properly.
|
||||
|
||||
To quote http://www.imagemagick.org/Usage/text/#draw:
|
||||
As of IM version 6.2.4, the "-draw text" operation no longer understands the use
|
||||
of '\n' as meaning newline, or the use of percent '%' image information escapes.
|
||||
(See Drawing a Percent Bug). These abilities, and problems, however remain
|
||||
available in the new IM v6 operator "-annotate". See the Annotate Text Drawing
|
||||
Operator below.

Font library handling differs too much on different systems and
|
||||
the available PHP toolkits are unable to return good diagnostics.
|
||||
</p><p>
|
||||
On Debian/Ubuntu, you may find your fonts in and under
|
||||
<code>/usr/share/fonts/truetype/</code>
|
||||
eg <code>'/usr/share/fonts/truetype/ttf-bitstream-vera/VeraMono.ttf'</code>
|
||||
</p><p>
|
||||
On OSX, they are probably in <code>/Library/Fonts/</code>
|
||||
eg <code>'/Library/Fonts/Times New Roman Bold Italic.ttf'</code>
|
||||
</p><p>
|
||||
On Windows, they are probably in <code>C:\\WINDOWS\Fonts\</code>
|
||||
eg <code>'C:\\WINDOWS\\Fonts\\comic.ttf'</code>
|
||||
</p><p>
|
||||
Of course, this will change if you deploy to a different server!
|
||||
so the best approach is to place your own TTF font file inside your private
|
||||
or public files directory and use that. Just give the filename with the
|
||||
'private://' or 'public://' scheme prefix and it should be found.

------
|
||||
README for the Image effect text test module.
|
||||
|
||||
This module contains several image styles to test text effects. It uses an image
|
||||
containing a grid and a font which are included in the install package as well.
|
||||
The image styles defined by this module start with 'text-test-'.

Introduction
|
||||
------------
|
||||
The Image style admin module extends the administrative interface for image
|
||||
styles by providing additional features.
|
||||
|
||||
Currently a duplicate, import and export image style feature are implemented.
|
||||
More features may be added in the future. These features typically allow you to
|
||||
more easily handle image styles. It allows us to more easily set up
|
||||
a test/showcase sute of styles. Finally, it allows everybody to test D8 image
|
||||
module features in real life.
|
||||
|
||||
This module is not a replacement for the features module
|
||||
(https://drupal.org/project/features). If you are serious about configuration
|
||||
management and want to distribute styles to other systems, use features.
|
||||
|
||||
Use this module for 1 time export/imports between different sites, "copy &
|
||||
paste" reuse within a site, and when reporting issues to the imagecache_actions
|
||||
issue queue.
