WOFF Barcode Web Fonts
The Web Open Font Format (WOFF) is a web font format that is compatible with multiple web browsers, including the latest versions of IE, Firefox, Chrome, Opera and Safari. It became a World Wide Web Consortium (W3C) Recommendation in December 2012. Web fonts allow webmasters to create web-based applications that include barcode, MICR and OCR typefaces without the need to install the fonts on the destination machine. With a Developer License purchase, IDAutomation fonts may be used in HTML, web pages and applications according to section 6 of the IDAutomation Software License Agreement, provided that domain restrictions are enabled for the fonts.
With the purchase of any Developer License or above, IDAutomation provides WOFF fonts, in addition to EOT and SVG fonts for compatibility with older browsers, for font packages, such as Code 128, GS1 DataBar, Code 39, Interleaved 2 of 5 and Universal Barcode Fonts. Purchases of Developer Licenses and above made prior to 2014 may receive the WOFF fonts with an active support agreement to the corresponding product.
Web fonts are downloaded by the browser and discarded after the user leaves the web page, so the fonts cannot be used for anything else. The following steps allow an easy implementation:
To investigate other methods of generating barcodes on the web that do not use fonts, visit the Internet & Web Page Barcode Implementation FAQ.
To enable support of web fonts on older browsers, other font types such as EOT (embedded opentype) and SVG may be included in CSS. Generally, EOT fonts work on older versions of IE and SVG fonts work on older versions of Safari on the iPhone and iPad. The Web Font Testing page attempts to display WOFF, EOT and SVG barcode fonts separately for testing purposes. IDAutomation also provides a CSS @font-face declaration that includes multiple web fonts with a single reference to the font-family.
