rawtopgm

Convert a raw greyscale image to a PGM image. More information: https://netpbm.sourceforge.net/doc/rawtopgm.html.

• 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
