"""usage: ttroundtrip [options] font1 ... fontN
|
|
|
|
Dump each TT/OT font as a TTX file, compile again to TTF or OTF
|
|
and dump again. Then do a diff on the two TTX files. Append problems
|
|
and diffs to a file called "report.txt" in the current directory.
|
|
This is only for testing FontTools/TTX, the resulting files are
|
|
deleted afterwards.
|
|
|
|
This tool supports some of ttdump's command line options (-i, -t
|
|
and -x) and they will in fact be passed to ttdump. Specifying -t
|
|
or -x implies ttcompile -i <originalfile> on the way back.
|
|
|
|
Normally all output from ttdump and ttcompile is suppressed,
|
|
-v (verbose) causes it to be shown.
