The Light editions of DTL Bezier- and IkarusMaster basically only have one major restriction: not more than 256 glyphs can be stored per editable glyph database. Changes in larger glyph databases, like for instance in the included FM Demo Font, can’t be saved. With the glyph editors it is possible to generate PostScript Type1 fonts for Windows though, and the DTL TraceMaster module is fully functional.

New! free: DTL LetterModeller 3.1
LeMo is a ﬁrst step towards the automation of type design processes, based on the underlying models for grapheme systems. Sliders can be used for parameterized altering the letterforms. Modiﬁed letters can be saved in the BE and IK formats and further processed in the included glyph editor, or with DTL Bezier- and IkarusMaster (Light, see above), or exported as EPS and SVG ﬁles. More info can be found on the LetterModeller website.
The 3.1 edition contains an enhanced glyph editor now, but this works in one direction; it can only be used for a newly-generated LeMo glyph database (the ﬁle can’t be re-opened). LeMo 3.1 can export (currently unhinted) CFF- and TrueType-based OpenType fonts too, which makes it a nice tool for for instance pattern-testing. For hinting respectively the autohinter of the AFDKO or ttfautohint can be used (see the Read Me ﬁle in the download), of course. website.
