Remarks

If a bitmap is embedded as a resource, and its BitmapImageType is Bmp, then the Bitmap object is read-only, and attempts to modify it will throw an exception. You must make a copy of it using Bitmap.DrawImage, and modify the copy, as shown in the following code:

Bitmap bmpMyBitmap = Resources.GetBitmap(Resources.BitmapResources.MyBitmap);
        Bitmap bmpCopy = new Bitmap(bmpMyBitmap.Width, bmpMyBitmap.Height);
        // copy the bitmap
        bmpCopy.DrawImage(0, 0, bmpMyBitmap, 0, 0, bmpMyBitmap.Width, bmpMyBitmap.Height);
        // now you may modify the copy using any Bitmap method
        bmpCopy.MakeTransparent(Microsoft.SPOT.Presentation.Media.Color.White);
