ppmtosixel

Convert a PPM image to DEC sixel format. More information: https://netpbm.sourceforge.net/doc/ppmtosixel.html.

• Convert a PPM image to DEC sixel format:

ppmtosixel path/to/file.ppm > path/to/file.sixel

• Produce an uncompressed SIXEL file that is much slower to print:

ppmtosixel -raw path/to/file.ppm > path/to/file.sixel

• Add a left margin of 1.5 inches:

ppmtosixel -margin path/to/file.ppm > path/to/file.sixel

• Encode control codes in a more portable (although less space-efficient) way:

ppmtosixel -7bit path/to/file.ppm > path/to/file.sixel
