Extract one line of values out of a PAM image. More information: https://netpbm.sourceforge.net/doc/pamslice.html.

• Print the values of the pixels in the n'th row in a table:

pamslice -row n path/to/image.pam

• Print the values of the pixels in the n'th column in a table:

pamslice -column n path/to/image.pam

• Consider the m'th plane of the input image only:

pamslice -row n -plane m path/to/image.pam

• Produce output in a format suitable for input to an xmgr for visualisation:

pamslice -row n -xmgr path/to/image.pam
