These three checkboxes influence how the particular hint
gets output. You can control, on a hint-by-hint basis, the font
types which should receive the hint. For example, there
may be some hints which work well for PostScript fonts but
not for TrueTypes. By setting these flags, you can have
one Fontographer database which is tuned to different font
formats. The “Bitmaps” checkbox refers to Fontographer’s
internal bitmap generation algorithms—if you discover some
hints which seem to throw off Fontographer’s automatic
bitmap generation, you can suppress those hints. That may
save time over having to hand-edit the poorly-created bitmap
images.
Of course, you don’t always have the option of choosing
hint format type. If you choose “Diagonal hint” from the
Hint type pop-up menu, Type 1 and Bitmaps both become
grayed, indicating that neither of those two choices are able
to accept diagonal hints.
