Now i am in a vc++ project. I am developing UI module with rich ribbon controls. In ribbon control buttons we can provide 16/32bit bitmaps using a image collection.

I am creating 32x320 bitmap using resource editor which contains 10 button images. When i am using this image collection in ribbon buttons these images are not transparent like VC's defult bitmap(writelarge, writesmall) it appears with white square borders.

I dont know what's wrong if any one knows explain me...

Thanks in advance

Solution 1

The bitmap editor in VS does not create 32bit bitmaps hence there is no alpha channel which is kind of absurd. Anyhow a quick look at google should provide you with the means to do what you need.

Hi SnowHow, thanks for the information. Another solution to solve this problem is using PNG images instead of bitmaps

Thanks in advance
