palmtopnm1

Usage

Overview

This program is part of Netpbm(1) .

palmtopnm reads a Palm Bitmap as input, from Standard Input or palmfile and produces a PPM image as output.

Alternatively (when you specify -transparent), palmtopnm writes the value of the transparent color in the Palm Bitmap to Standard Output.

Palmtopnm can convert Palm Bitmaps with the following features. This does not mean that it doesn't handle other features. These are just the ones we found worth mentioning.

Options

In addition to the options common to all programs based on libnetpbm (most notably -quiet, see
Common Options ⟨index.html#commonoptions⟩ ), palmtopnm recognizes the following command line options:

-verbose

Display various interesting information about the input file and process.

-transparent

If the Palm Bitmap has a transparent color set, palmtopnm writes the value for that color to Standard Output in the form #RRGGBB, where RR, GG, and BB are two-digit hexadecimal numbers indicating a value in the range 0 through 255. If no transparent color is set in the Bitmap, palmtopnm writes nothing. palmtopnm does not generate any output image when you specify -transparent.

-rendition N

Palm Bitmaps may contain several different renditions of the same image, with different depths. By default, palmtopnm operates on the first rendition (rendition number 1) in the image. This switch allows you to operate on a different rendition. The value must be between 1 and the number of renditions in the image, inclusive.

-showhist

This option causes palmtopnm to write a histogram of colors in the input file to Standard Error.

Limitations

You cannot generate a transparency mask if the Palm Bitmap has a transparent color. However, you can still do this with ppmcolormask with a Netpbm pipe similar to:

palmtopnm bitmap.palm | ppmcolormask `palmtopnm -transparent bitmap.palm`
