| usage: %s [-hvis] [-t <table>] [-x <table>] TrueType-file [TTX-output-file] |
| Dump a TrueType font as a TTX file (an XML-based text format). If the |
| TTX-output-file argument is omitted, the out put file name will be |
| constructed from the input file name, like so: *.ttf becomes *.ttx. |
| Either way, existing files will be overwritten without warning! |
| |
| 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. |
| The files will be saved in a directory. The name of this |
| directory will be constructed from the input filename (by |
| dropping the extension) or can be specified by the optional |
| TTX-output-file argument. |
| -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. |
