The way we do that with Wenlin CDL is, we have a customized text editor that recognizes <cdl>...</cdl> elements, embedded in what may otherwise be plain text. Each CDL description is displayed as a single CJK character. The CDL interpreter converts each CDL description into outlines for each strokes, which can be output as TrueType, Postscript, SVG, etc. For displaying on the screen, the interpreter (built into the text editor) produces FreeType outlines, which get rasterized by FreeType, then sent to the screen as bitmaps. This can be done without assigning a private-use code point to the character. (We do also use a lot of private-use code points.)
Thanks for the explanation, I'm sure this is a good way.
Converting a CDL description into an outline is complicated, and probably too off-topic to discuss on the FreeType list. Thanks for your interest in CDL, and thanks to Werner for mentioning it! I'm happy to answer questions about it.
Yes. I do agree that converting a description into the outline of an CJK character is complicated, given that the variation and transformation of each component glyph might be complex, and the CDL work you have accomplished is amazing.
Thanks & Regards,
Dennis
