Does greyscale make sense for dtx_save_glyphmap_stream? #5

Closed nigels-com closed 7 years ago

nigels-com commented 7 years ago

I'm interested in using libdrawtext with pre-cooked glyphmap files, perhaps gzipped.

I noticed in the implementation that P6 PPM RGB mode is being used, but that P5 PGM greyscale could be used to reduce the file size. Seems like dtx_load_glyphmap_stream could be extended to support P5 for input.
