CSS Orientation Test are special-purpose OpenType fonts. This open source project provides all of the source files that were used to build these OpenType fonts by using the AFDKO makeotf tool.
Send suggestions for changes to the CSS Orientation Test project maintainer, lunde@adobe.com, for consideration.
The installable font resources (font binaries) are not part of the source files. They are available at https://github.com/adobe-fonts/css-orientation-test/ The latest version of the font binaries is 1.005 (April 4th 2015).
For building binary font files from source, installation of the Adobe Font Development Kit for OpenType (AFDKO) is necessary. The AFDKO tools are widely used for font development today, and are part of most font editor applications.
The key to building OpenType fonts is makeotf, which is part of AFDKO. Information and usage instructions can be found by executing makeotf -h.
In this repository, all necessary files are in place for building the OpenType fonts. For example, build a binary OTF font for the full-width version like this, which also includes a post-process for inserting a “stub” ‘DSIG’ table:
% makeotf -f cidfont.ps -r -ch UnicodeAll-UTF32-H % sfntedit -a DSIG=DSIG.bin CSSFWOrientationTest.otf % sfntedit -f CSSFWOrientationTest.otf
That is all.
