pamtotiff
Convert a PAM image to a TIFF file.
TLDR
Convert a PAM image to a TIFF image
$ pamtotiff [path/to/input_file.pam] > [path/to/output_file.tiff]
Explicitly specify a compression method for the output file
$ pamtotiff -[none|packbits|lzw|g3|g4|flate|adobeflate] [path/to/input_file.pam] > [path/to/output_file.tiff]
Always produce a color TIFF image, even if the input image is greyscale
$ pamtotiff -color [path/to/input_file.pam] > [path/to/output_file.tiff]
