Even/odd fill
The other filling technique is called an even-odd fill. You
should use the even/odd fill type for PostScript Type 3 fonts
or for modifying the behavior of the Remove Overlap
command. An outside path is not filled until it crosses a
path. The area that it crosses is filled; the next area the
path crosses becomes unfilled, and so on.
In the previous illustration of the “O,” even/odd filling would
give the desired result even if both paths were clockwise.
Correct path direction
Path directions can be automatically corrected—that is, you
can tell Fontographer to examine all the path directions and
reorder them if necessary. Path directions must be correctly
set for proper filling of characters. Choosing “Correct Path
Direction” from the Element menu tells Fontographer to
examine all the selected characters and, if necessary,
automatically adjust their path directions.
Outer paths will be set to clockwise, inner paths to
counterclockwise. When required, Fontographer
automatically (but temporarily) reverses these (for
instance, when generating Type 1 fonts).
