Convert a Windows ICO file to a PAM file. More information: https://netpbm.sourceforge.net/doc/winicontopam.html.
- Read an ICO file and convert the best quality image contained therein to the PAM format:
winicontopam path/to/input_file.ico > path/to/output.pam
- Convert all images in the input file to PAM:
winicontopam -allimages path/to/input_file.ico > path/to/output.pam
- Convert the n'th image in the input file to PAM:
winicontopam -image n path/to/input_file.ico > path/to/output.pam
- If the image(s) to be extracted contain graded transparency data and an AND mask, write the AND mask into the fifth channel of the output PAM file:
winicontopam -andmasks path/to/input_file.ico > path/to/output.pam
