[-version] [-help] fontfile1 fontfile2
Sfddiff compares (or merges) two font files (in any format fontforge can read) and checks for differences.
It will notice:
If the -merge
flag is specified the following
argument should be the name of an output file into which
sfddiff will store a merged version of the two fonts. This will
contain everything from fontfile1 as well as any characters
present in fontfile2 but not in fontfile1. For any characters
with different outlines or references, the background of the
character will contain the splines from fontfile2 (sadly
references can not be placed in the background).
If the -ignorehints
flag is specified, then no
hint differences will be reported.
-help
will provide a mini description and will
list the available options.
-usage
will list the available options.
-version
will display the current version of
sfddiff.
