## NAME

xpmtoppm - convert an X11 pixmap into a PPM image

## SYNOPSIS

xpmtoppm [--alphaout={alpha-filename,-}] [-verbose] [xpmfile]

## DESCRIPTION

Reads an X11 pixmap (XPM version 1 or 3) as input. Produces a PPM file as output.

## OPTIONS

--alphaout=alpha-filename
  xpmtoppm creates a PBM file containing the transparency mask for the image. If the input image doesn't contain transparency information, the alpha-filename file contains all white (opaque) alpha values. If you don't specify --alphaout, xpmtoppm does not generate an alpha file, and if the input image has transparency information, xpmtoppm simply discards it.

  If you specify - as the filename, xpmtoppm writes the alpha output to Standard Output and discards the image.

  See pnmcomp for one way to use the alpha output file.

--verbose
  xpmtoppm prints information about its processing on Standard Error.

## LIMITATIONS

The support to XPM version 3 is limited. Comments can only be single lines and there must be for every pixel a default colorname for a color type visual.
