TTXT – MODE 7 for the 21st century

+

TTXT is an outline font based on the characters produced by the + Mullard SAA5050 series of Teletext Character Generators. The + SAA5050 is familiar to those of a certain age as the one that + produced the MODE 7 display on the BBC + Microcomputer. It generates characters from a 5 × 9 pixel + matrix, smoothing diagonal lines to produce an interlaced 10 × + 18 matrix for each character. This font it generated by an + extension of the SAA5050’s smoothing algorithm. In addition to + the characters available from the SAA5050 itself, the font + includes characters from the other chips in the family + (including Cyrillic and Hebrew alphabets), an Arabic alphabet + found in an EBU document, and various other useful glyphs. All + glyphs are drawn on the same 5 × 9 pixel grid, albeit with a + slight variation to let the Arabic characters join up.

+ +

The outline version of the font is generated by an ANSI C program + which emits a Spline Font Database file for use with + Fontforge, which + can convert it into most reasonable font formats.
