usage: ttdump [-hvisf] [-t <table>] [-x <table>] src [target]
|
|
ttdump [-hvisf] [-t <table>] [-x <table>] src1 ... srcN directory
|
|
|
|
Dump one or more TrueType/OpenType fonts as TTX files (an XML-based
|
|
text format).
|
|
|
|
Options:
|
|
-h Help: print this message
|
|
-v Verbose: messages will be written to stdout about what is
|
|
being done.
|
|
-i Disassemble TT instructions: when this option is given, all
|
|
TrueType programs (glyph programs, the font program and the
|
|
pre-program) will be written to the TTX file as assembly
|
|
instead of hex data.
|
|
-s Split tables: save the TTX data into separate TTX files per
|
|
table and write one small TTX file that contains references
|
|
to the individual table dumps. This file can be used as
|
|
input to ttcompile, as long as the table files are in the
|
|
same directory.
|
|
-f Force overwriting existing files.
|
|
-t <table> Specify a table to dump. Multiple -t options
|
|
are allowed. When no -t option is specified, all tables
|
|
will be dumped.
|
|
-x <table> Specify a table to exclude from the dump. Multiple
|
|
-x options are allowed. -t and -x are mutually exclusive.
