[comp.lang.postscript] Type 1 vs. Type 3 Font Files

chanel@mensa.usc.edu (chanel summers) (03/07/91)

Can anyone explain to me the difference between Type 1 and Type 3 font
formats (or perhaps point me to a suitable reference point)?  I have several
Type 3 font files (.PFA format) which seem incompatible with my font
downloading software.  It wants Type 1 files with a .PFB extension.

Also, is it necessary to have a font metrics file (.AFM) for each .PF? file?
And, can I just send the .PF? file (with or w/o .AFM) directly to the printer
and expect it to stick in the FontDirectory?

Any help greatly appreciated!
