You may abbreviate any option to its shortest unique prefix. You may use two hyphens instead of one to delimit an option. You may separate an option from its value with whitespace instead of =.
This program is part of Netpbm.
pamtouil reads a PNM or PAM image as input and produces a Motif UIL icon file as output. If the input is PAM, it may be either a regular grayscale or color image or grayscale+transparency or color+transparency. Where the transparency channel is present, pamtouil renders pixels that are more than half transparent as transparent in the output.
In the UIL's colormap, pamtouil uses the color names from the RGB database -- the same one ppmmake uses. Where a color in the input does not exactly match one of the colors named in the RGB database, pamtouil uses the closest color named in the RGB database.
In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options), pamtouil recognizes the following command line option:
Before May 2002, pamtouil was called ppmtouil and had no way to specify transparency.
