Description

PPM files are simply RGB pixels in an array. Its super simple to not only parse, but also create, slice and do other things with. JPG, bitmaps and etc other formats have complex headers and sometimes even lookup tables. Making things like slicing very complex unless you use a library.

I was surprized the tool does not support PPM so hoping this super simple format may be supported.
