asciitopgm

Convert ASCII graphics into a PGM file. More information: https://netpbm.sourceforge.net/doc/asciitopgm.html.

• Read ASCII data as input and produce a PGM image with pixel values that are an approximation of the “brightness” of the ASCII characters:

asciitopgm path/to/input_file > path/to/output_file.pgm

• Display version:

asciitopgm -version
