I am trying to display a raster in IV.  The format for an image in the
raster class is a TIFF file.  The original image I had was in GIF
format.  I converted it to TIFF only to realize how enormous color TIFF
format files were (since color TIFF supports 24 bit color).  A file of
the size that resulted from the TIFF format conversion is very
undesirable.  Is there any other format image that can be displayed in
IV?  How have people in the past who have wanted to display color TIFF
images in IV dealt with this problem?  The resolution I am going to be
displaying my image at is only 8 bit color so it would be desirable to
find a way to store the image in other than the color TIFF format and
still display.  Any information or experience would be greatly
appreciated.

Thanks,
Jason
