Hi Andreas,

When GetClipboard() grabs a clipbord image as a brush, it does not retain the alpha-channel of the copied image. Can this be changed in a future version?

Thanks,

I tried to implement this but I couldn't find an app which would paste alpha channel data to the clipboard. What application did you use? Another problem is that there are two ways of embedding an alpha channel inside a clipboard image (either by using a separate IFF chunk or by creating a 32-bit planar image). This is pretty complicated stuff so I decided to leave it out because I can't test it here.

In OS4, any icon information window will allow you to copy and paste images with alpha-channel data---using either hotkeys (Amiga+C and Amiga+V) or going through the menu (under Icon Image).

Also, Multiview will copy images with the alpha-channel data to the clipboard (though you cannot paste with Multiview).

Ok, good to know. Then I can try and see how OS4 is doing this and should be able to get alpha support in.
