<title>What is the PHP Exif Library?</title>
|
|
|
|
<para>The PHP Exif Library (called PEL for short) is a library
|
|
written in {@link http://www.php.net/ PHP} which will allow you to
|
|
manipulate {@link http://www.exif.org/ Exif} data. This is the
|
|
data that digital cameras place in their images, such as the date
|
|
and time, shutter speed, ISO value and so on.</para>
|
|
|
|
<para>PEL makes it easy to parse Exif data stored in JPEG and TIFF
|
|
images. Once an image has been loaded, the data can be changed at
|
|
will by manipulating the objects representing the data. The
|
|
objects can be saved again to produce a valid image.</para>
