1 2 Notes about fonts in this directory 3 4 Ahem.ttf - ACID3 test font 5 6 markXXX.ttf and markXXX.otf 7 8 These fonts are autogenerated with FontForge using the Python script mark-generate.py. 9 See the comments in that file for more information on how to run the script. 10 11 The markX.ttf and markX.otf fonts contain a single glyph for the X character consisting 12 of three stacked boxes. The mark2X.ttf and mark2X.otf files also contain just a glyph for the 13 character X but the glyph is similar to the space mark character. The markXmark2Y.ttf has 14 two glyphs, the first glyph for X and the second glyph for Y. 15 16 The markA.eot and markB.eot files are for EOT-related testing. The markA.eot file is just 17 a copy of markA.ttf while markB.eot is a valid EOT file embedding the contents of markB.ttf 18 with a null root string (so it can be used in IE without domain-specific restrictions). 19 20 21 PositioningTest1.ttf, PositioningTest2.ttf 22 23 These fonts were generated with FontForge and then OpenType tables added with MS VOLT. 24 The glyphs are from Charis SIL (see http://scripts.sil.org/CharisSILFont), released under the 25 Open Font License. 26 27 In both fonts, the lowercase 'o' glyph should appear raised when rendered. Font 1 uses a GPOS 28 positioning rule to achieve this, so it tests whether vertical deltas are being handled 29 correctly. Font 2 uses a GSUB substitution to replace the 'o' with a glyph that has already 30 been offset within the em-square, so no vertical delta is involved. 31 32 Finally, the capital 'O' character maps directly to the shifted 'o' glyph, so this can be 33 used for comparison without requiring any OpenType layout support.
