Here is an example:
d:\tex\dvii>fontdiff.cmd a b perl D:\scripts\fontdiff.pl a b Fonts in a.dvi NOT in b.dvi: ------------------------------ f:[XX/cmbx10/1000]::1af22256 ------------------------------ Fonts in b.dvi NOT in a.dvi: ------------------------------ f:[XX/cmti10/1000]::fd00273a f:[XX/cmsl10/1000]::70ae304a ------------------------------ Fonts in common that have DIFFERENT checksums: ------------------------------ ------------------------------There are a variety of options:
fontdiff.pl 0.02 (23 September 2001) USAGE: fontdiff [options] dvi_file1 dvi_file2 OPTIONS -c : ignore checksum when finding font differences -C : do NOT ignore checksum when finding font differences (DEFAULT) -n : ignore font number when finding font differences (DEFAULT) -N : do NOT ignore font number when finding font differences -s : ignore font scaling when finding font differences -S : do NOT ignore font scaling when finding font differences (DEFAULT) -l : list fonts for each file Note: if -c is chosen, the checksum difference table will not appear. Thus, 'fontdiff' (with no options) is equivalent to 'fontdff -C -n -S'
