[Manifold-l] Image visibility (version 7.latest)

[Springfield Harrison]

Hello:

         I've just successfully imported and Georeferenced a BMP RGBa map 
image.  Only the graticule seems to be visible initially.  Unticking 
"alpha" in the layer pane seems to make the whole image visible (?).

         Now I've imported it into another project, added it to a map but 
can only see the graticule.  Monkeying with the "alpha" attribute makes no 
difference.  What is "alpha"?  Should I use a different kind of image?

         Can anyone suggest what might be going on here and how I can 
actually see the image?  Top or bottom and opacity have no effect.

         Also, where should our questions be directed?  I see this list is 
falling out of favour but notice that there are several fora in use.  Which 
is the one?  I only use Manifold intermittently so don't always get the 
latest hints.

                 Thanks very much . . . . .
