A friend of mine suggested that I ought to announce the new version of
xloadimage on this forum as well as the others I currently follow, so
here we go.
Xloadimage version 2.0 is now available by anonymous ftp from
expo.lcs.mit.edu in /contrib/xloadimage.2.0.tar.Z. It will show up on
comp.sources.x in the near future. If you don't have access to either
of these sources, I can email a copy to you but beware that it's a
375k distribution in 9 shar files.
If you are unfamiliar with xloadimage, it is a utility designed to
display a wide range of image formats on a wide range of X11 displays,
doing whatever processing is necessary to display the image
automatically. A number of image processing functions such as
zooming, gamma equalization, and smoothing are also available.
The following help listing shows most of the capabilities:
Usage: xloadimage [global options] {[image options] image_name ...}
