NB Quiet zones - The barcode object includes space to the right/left or top/bottom only when the specification states a \'quiet zone\' or \'light margin\'. All the examples below also have CSS property set on the barcode object i.e. padding: 1.5mm;
NB EAN-13, UPC-A, UPC-E, and EAN-8 may all include an additional bar code(EAN-2 and EAN-5) to the right of the main bar code (see below).
A nominal height and width for these barcodes is defined by the specification. \'size\' will scale both the height and width. Values between 0.8 and 2 are allowed (i.e. 80% to 200% of the nominal size). \'height\' can also be varied as a factor of 1; this is applied after the scaling factor used for \'size\'.

| EAN13 | Standard EAN-13 barcode. Accepts 12 or 13 characters (creating checksum digit if required). [0-9] numeric only. | |
| ISBN | Standard EAN-13 barcode with \'ISBN\' number shown above [shown at height="0.66"] | |
| ISSN | Standard EAN-13 barcode with \'ISSN\' number shown above [shown at size="0.8"] |

| UPCA | UPC-A barcode. This is a subset of the EAN-13. (098277211236) Accepts 11 or 12 characters (creating checksum digit if required). [0-9] numeric only | |
| UPCE | UPC-E barcode. Requires the UPC-A code to be entered as above (e.g. 042100005264 to give 425261). NB mPDF will die with an error message if the code is not valid, as only some UPC-A codes can be converted into valid UPC-E codes. UPC-E doesn\'t have a check digit encoded explicity, rather the check digit is encoded in the parity of the other six characters. The check digit that is encoded is the check digit from the original UPC-A barcode. | |
| EAN8 | EAN-8. Accepts 7 or 8 characters (creating checksum digit if required). [0-9] numeric only |
UPC-A, UPC-E, EAN-13, and EAN-8 may all include an additional bar code(EAN-2 and EAN-5) to the right of the main bar code.
| CODE | DESCRIPTION | BARCODE |
| EAN2 | EAN-2 supplement barcode. mPDF does not generate EAN-5 barcode on its own; see supplements below. Used to denote an issue of a periodical. EAN-2 supplement accepts 2 digits [0-9] only, EAN-5 five. | |
| EAN5 | EAN-5 supplement barcode. mPDF does not generate EAN-5 barcode on its own; see supplements below. Usually used in conjunction with EAN-13 for the price of books. 90000 is the code for no price. | |

| EAN8P5 | EAN-8 barcode with 5-digit EAN-5 supplement (55123457 90000) | |
These all have sizes fixed by their specification. Although they can be altered using \'size\' it is not recommended. \'height\' is ignored.

| IMB | Intelligent Mail Barcode - also known as: USPS OneCode 4-State Customer Barcode, OneCode 4CB, USPS 4CB, 4-CB, 4-State Customer Barcode, USPS OneCode Solution Barcode. (01234567094987654321-01234567891) Accepts: Up to 31 digits (required 20-digit Tracking Code, and up to 11-digit Routing Code; this may be 0, 5, 9, or 11 digits). If the Routing code is included, it should be spearated by a hyphen - like this example. | |
| RM4SCC | Royal Mail 4-state Customer barcode (SN34RD1A). Accepts: max. 9 characters. Valid characters: [A-Z,0-9] Checksum digit: automatic. | |
| KIX | Dutch KIX version of Royal Mail 4-state Customer barcode (SN34RD1A). Valid characters: [A-Z,0-9]. Checksum digit: automatic. | |
| POSTNET | POSTNET barcode. Accepts 5, 9 or 11 digits. Valid characters: [0-9]. Checksum digit: automatic. | |
| PLANET | PLANET barcode. Accepts 11 or 13 digits. Valid characters: [0-9]. Checksum digit: automatic. |
These barcodes are all of variable length depending on the code entered. There is no recommended maximum size for any of these specs, but all recommend a minimum X-dimension (width of narrowest bar) as 7.5mil (=0.19mm). The default used here is twice the minimum i.e. X-dim = 0.38mm.
The specifications give a minimum height of 15% of the barcode length (which can be variable). The bar height in mPDF is set to a default value of 10mm.
\'size\' will scale the barcode in both dimensions. mPDF will accept any number, but bear in mind that size="0.5" will set the bar width to the minimum. The \'height\' attribute further allows scaling - this factor is applied to already scaled barcode. Thus size="2" height="0.5" will give a barcode twice the default width (X-dim=0.76mm) and at the default height set in mPDF i.e. 10mm.
