rawtopgm
Convert a raw greyscale image to a PGM image.
TLDR
Convert a raw greyscale image to a PGM image
$ rawtopgm [width] [height] [path/to/image.raw] > [path/to/output.pgm]
Convert a raw greyscale image to a PGM image, assume the image to be a square
$ rawtopgm [path/to/image.raw] > [path/to/output.pgm]
Convert a raw greyscale image in which the pixels come bottom-first instead of top-first to a PGM image
$ rawtopgm [width] [height] -bottomfirst [path/to/image.raw] > [path/to/output.pgm]
Ignore the first n bytes of the specified file
$ rawtopgm [width] [height] -headerskip [n] [path/to/image.raw] > [path/to/output.pgm]
Ignore the last m bytes of each row in the specified file
$ rawtopgm [width] [height] -rowskip [m] [path/to/image.raw] > [path/to/output.pgm]
Specify the maxval for the grey values in the input to be equal to N
$ rawtopgm [width] [height] -maxval [N] [path/to/image.raw] > [path/to/output.pgm]
Specify the number of bytes that represent each sample in the input and that the byte-sequence is to be interpreted as little-endian
$ rawtopgm [width] [height] -bpp [1|2] -littleendian [path/to/image.raw] > [path/to/output.pgm]
