Hi , I combine 2 image The small image I rotated it , made it transparent and combine it with large image But the small image can't transparent If i change the transparent to yellow => it ok but not with transparent Code:rotate.BackgroundColor = Aurigma.GraphicsMill.RgbColor.Transparent;
Please help me Thanks Code:private void AvandceCombine()
{
//Load background image
Aurigma.GraphicsMill.Bitmap bitmap =
new Aurigma.GraphicsMill.Bitmap(@"D:\Program Files\Aurigma\Graphics Mill 3.5 for .NET 1.1\Web Demos Source Code\GraphicsMillWebCS\cooler.png".Replace(@"\","/"));
//Load small image (foreground image)
Aurigma.GraphicsMill.Bitmap smallBitmap =
new Aurigma.GraphicsMill.Bitmap(@"D:\Program Files\Aurigma\Graphics Mill 3.5 for .NET 1.1\Web Demos Source Code\GraphicsMillWebCS\500off.png".Replace(@"\","/"));
PixelFormatConverter pixelFormatConverter = new PixelFormatConverter();
pixelFormatConverter.DestinationPixelFormat = PixelFormat.Format24bppRgb;
pixelFormatConverter.ApplyTransform(smallBitmap);
//Rotate at 5 degrees with medium quality
Aurigma.GraphicsMill.Transforms.Rotate rotate =
new Aurigma.GraphicsMill.Transforms.Rotate();
rotate.Angle = 30;
[b]rotate.BackgroundColor = Aurigma.GraphicsMill.RgbColor.Transparent;[/b]
rotate.InterpolationMode = Aurigma.GraphicsMill.Transforms.InterpolationMode.MediumQuality;
if (rotate.IsPixelFormatSupported(PixelFormat.Format24bppRgb))
[b]rotate.ApplyTransform(smallBitmap);[/b]
//Draw foreground image on background with transparency
smallBitmap.Draw(bitmap, 10, 110,
smallBitmap.Width, smallBitmap.Height,
Aurigma.GraphicsMill.Transforms.CombineMode.Alpha, 1f,
Aurigma.GraphicsMill.Transforms.InterpolationMode.LowQuality);
bitmap.Save(@"C:/background.png");
}

hi,
I found solution
We must use "PixelFormat.Format32bppArgb" instead PixelFormat.Format24bppArgb
pixelFormatConverter.DestinationPixelFormat = PixelFormat.Format32bppArgb;
This's great tool
Thanks
