Hi, to make image lighter i apply following Levels transform, which is good with RGB , but failing if image is CMYK {Format32bppCmyk} Code:
using (var image = new Aurigma.GraphicsMill.Bitmap(in_file))
{
image.ColorAdjustment.Levels(0, 1, 0, (float) 1.2, 1, HistogramMode.Sum);
}
Code:Aurigma.GraphicsMill.UnsupportedPixelFormatException was unhandled
HResult=-2146233088
InnerSource=Levels: 3
Message=The specified pixel format is not supported.
Source=Aurigma.GraphicsMill
