Hi!
I am trying to draw something into an Image with a prior call to
gc.setAlpha(). It doesn't matter to what value I set the parameter, the
image stays empty. The same method painting with a "direct" gc has no
problems with the alpha blending.
Has anyone an idea? Is this not supported (yet)? I am using WindowsXP
with SWT 3.128 (i.e. M6).
Thanks,
Michael

Hello Michael,
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet10.java?rev=HEAD
uses the setalpha and it works there. Although I have run into a similar
thing as you have wher the setalpha does not work but by setting the
imagedatas transparentPixel = 1 I have managed to set the transparency.
Hopefully we are using the api incorrectly and someone here will help us
fix it.
