I have used GIMP before, but didn't know it supports 32 bit BMP files. When I find some more time I might give it a try. Interesting.

I have created transparent bitmaps with editor for use in my applications, but I have no use for 32-bit bmps as I now use the GDI+ library and it supports loading png files. However, if you want to create an example with loading just BMPs, you could create them with GIMP. http://www.gimp.org/windows/ @Marc

Maybe you can use another library to load PNG files? Maybe this one: http://www.codeguru.com/cpp/g-m/bitmap/otherformats/article.php/c4899/ ?

Could you possibly write another version that simply loads a BMP? I believe the latest version of BMP does support transparency. Thank you Hello

I have VC++ 6.0 which doesn’t seem to have the CImage class (atlimage.h).

Could you possibly write another version that simply loads a BMP?

I believe the latest version of BMP does support transparency.

Thank you

Did you try to get the HDC of the layered window? Maybe that HDC is a 32bit device context including the alpha channel…

Hi, Marc,
Is it possible the inverse operation, i.e. saving A channel in a (png) file given a layered window?

This is just a 32bit device context, so RGB and A channels. If you want to add PNG based buttons, load the PNGs (maybe using CImage class) and then render those PNGs at the right position in the hDC. Store the coordinates of your PNG buttons somewhere so you can use the coordinates in your WM_MOUSEMOVE and mouse button messages. Once everything is rendered to hDC, call UpdateLayeredWindow. I think this should give you what you want. In my example I have this device context called hDC which will be used in the call to UpdateLayeredWindow.

Could you maybe extend this example to show how to use UpdateLayeredWindow with UI Controls like buttons etc?:) I cant find any solution for this. What i exactly need is to know how i can Use my PNG with alpha channel as background and a set of other pngs as buttons/ui controlls Hi, thanks for that post.
