Hi

I was wondering how to Restore Transparent Bitmaps.

The functions I have used (eg WinApi.StretchDIBits & WinApi.SetDIBitsToDevice)
do not seem to support transparency. HostBitmaps are 24 bit, and don't (I think)
support transparency.

I had a look on MSDN, and found a reference to AlphaBlend
(http://msdn.microsoft.com/en-us/library/ms532324(VS.85).aspx)
whick looks like it might be on the right track. But there is no interface
to AlphaBlend in the BlackBox WinApi interface.

I thought that it might be desirable to be able to draw LaTeX equations (etc)
with a transparent background.

Any suggestions would be welcome.

Thanks

Robert
