ReadImg
DESCRIPTION
This module reads an image file and converts it into an Explorer lattice.
The ImageVision library is used for all image manipulation, so the file
formats supported are those that ImageVision supports. These formats
currently include SGI (.rgb format), FIT (SGI tiled format), GIF, TIFF,
and PhotoCD. Support for additional formats can be added with the
appropriate shared object loaded into /usr/lib/ImageVision/filefmt.
Images of char, short, int, long, float, and double, and of any number
of channels are supported.

Constraints: 2..3-D.
uniform.
This is the output image.
PROBLEMS
Bit images are not supported.
Colormap images are not properly supported. The result will be a monochrome
image with the map values. The colormap is lost in the conversion to a lattice.
The file browser widget does not correctly browse files on
remote machines. The remote filename can be entered in the selection
box, but the option menu is inoperable.
