[comp.sys.cbm] GEOS Font file format

prindle@NADC.ARPA (Frank Prindle) (06/28/88)

Could someone who has figured it out please explain the format of a GEOS
font file? I have been able to determine that there is a separate sequential
chain for each point size, and that each point size starts of with some
control information and 96 pointers corresponding to (I assume), the 95
printing ASCII characters and the "undefined" character (full height vertical
line). What I can't figure out is the organization of the subsequent bitmap
relative the the aforementioned pointers. I assume that "bold" and "italic"
renderings are obtained by perturbing the basic bitmap for a character in
a pre-defined way; is this true?
Thanks,
Frank Prindle
