Hello,

Thank you for your excellent explanation, I really starting to understand the application as a whole thanks to you.
There's just one thing I don't quite understand (there's always a thing I don't understand it seems :) ): You say everything is stored in glyph-files and then build to a truetype font-file, which is good, but what if you want to read an existing truetype font-file? Is that an option? And if so: which package or class is responsible for the conversion from the truetype font-file to all the seperate glyph-files for all the glyphs in the application?
Yet again: thank you for the response and help, it's really great to receive so much help from you.
Kindest regards,

Yannik
