    Resource files and GIF files

    Noticed when creating a resource file, only a bmp option is available... Problem with BMP is they always have a background (or enclosing rectangle)... With gifs you can have them with transparent Background.. Thing is i would like to animate an image with a specific shape (ball/aircraft, etc) on a client window... But now the BMP has this white block around it! How do i create a transparent background resource file?

    The animated example demonstrates how to eliminate the above problem.

    Maybe am dumb, can't read anywhere the author talks about making the ball background transparent... Perhaps all he did was to have the background white, which wont show on a white window anyway.... Please indicate if i skipped some statements there... sometimes i read too fast missing important fine lines

    You can add, of course, GIF or any format in resource
    (read MSDN...)

    Unfortunately, the author discusses this subject in generalities and really doesn't get into the details. Download the complete anim_one package and review the CreateBitmapMask function.

    CreateBitmapMask is discussed elsewhere: Graphics Device Interface - Transparent Bitmaps.

    But, when it comes to GIFs, just include it into your resorce script.

    128 GIF DISCARDABLE MyPicture.gif

    and use it like this:

    hRsrc = FindResource (hInstance, MAKEINTRESOURCE(128), TEXT("GIF"));
