sfddiff - compare two font files

SYNOPSIS


sfddiff [--help] [--ignorehints] [--ignorenames] [--ignoregpos] [--ignoregsub]
[--ignorebitmaps] [--exact] [--warn] [--merge outfile] [--usage] [--version] fontfile1
fontfile2

DESCRIPTION


The program sfddiff compares two font files, which may be in any format fontforge(1) can
read. It will notice the following differences:

1) Characters are present in one font but not in the other.

2) Characters are present in both fonts but have different sets of outlines or
references. The outlines may be compared so that only exact matches are accepted,
or so that a fuzzier match is used. Similarly references may need to match
exactly, or may be matched after an unlink.

This fuzzy comparison is useful when comparing truetype and postscript fonts, or
when comparing a font with references to one without.

3) The postscript hints or truetype instructions are different.

4) The font names (the truetype `name' table) differ.

5) The kerning (and other `gpos' information) differs.

6) The ligatures (and other `gsub' information) differ.

7) Any bitmap strikes present in one font but not in the other.

8) Any bitmap characters present in one strike of one font but in the equivalent
strike of the other.

9) Any bitmap characters which differ.

OPTIONS


--help Provide a description with a list of the available options.

--ignorehints
Suppress the reporting of hint/instruction differences.

--ignoregpos
Suppress the reporting of kerning (and other `gpos') differences.

--ignoregsub
Suppress the reporting of ligature (and other `gsub') differences.

--ignorenames
Suppress the reporting of name string differences.

--ignorebitmaps
Suppress the reporting of bitmap differences.

--exact
Require outlines to match exactly.

--warn Warn if the outlines/references are slightly different.

--merge outfile
Store a merged version of the two fonts into the specified output file. The merged
data will be based on sfdfile1, as well as any characters present in sfdfile2 but
not in sfdfile1 will be added, and the outlines of sfdfile2 will be placed in the
background. Finally, for any characters with different outlines or references the
background of the character will contain the outlines from sfdfile2 (references
will be unlinked into outlines and those outlines also will be added).

--usage
Display the usage description.

--version
Display the current version.
