Summary0003237: 0001817: Access violation when using SetBitmapPixelFormat
DescriptionWhen changing BitMapPixelFormat from 32bit to 8bit an access violation occurs in function BitmapToMemoryStream.
This is because variable ImageSize is not adjusted to the new, smaller size of the Bitmap.
Additional InformationTo make here so:
        if SourceBitmapFormat = pfDevice then
          Result.Write(Bits^, ImageSize)
        if SourceBitmapFormat = pf32bit then
          Result.Write(Bits^, ImageSize div 4)
          Result.Write(Bits^, ImageSize div 3);

Or to alter for all bitmap formats
TagsNo tags attached.
