CImage::Draw - Image format?

[Jaran Nilsen]

Hi. I am trying to use the CImage class from ATL to handle images in my GDI game. I manage to make it draw the images, or at least some formats. It says in the documentation that the CImage::Draw function is supposed to support both transparency and alpha channel. But I can't seem to make that work. I was wondering if it's just the format that I save my images in that is wrong? I have tried different PNG formats and GIF, but none work correctly. As far as I understand the documentation I am supposed to be able to create a PNG containing transparent color and alpha channel and the Draw function will take care of the rest when I call it... Is that the case? Does anyone know what format I have to save my images in to make them work properly? I tried to save the image with transparency and alpha channel as PNG-24 (from Photoshop), but the transparent color is just semi-transparent when I render it in my game. Anyone know what's wrong? Thanks.
