Opps that didn't work (convert to 1 bit) which resulted in an error when I
attempted to save as a TIFF file (TIFF save cannot handle indexed images with
alpha channel.)
I should I guess explain what I am trying to do. I am creating photo realistic
scenery for use withing Flight Simulator X.
What I have to do is create a 'water mask' which is done by creating a layer and
then using that layer to 'paint out' all the water areas using a BRUSH which is
of  color BLACK (0,0,0). This I have already done. I select that layer and then
convert it to 1 bit and then attempt to EXPORT it as a TIFF image with NO
COMPRESSION. That is when I get the error. Is there a way around that.
