Hi, I've been using the following link to try and convert images from CMYK to RGB to be shown in a web browser but am having problems with images being too bright. http://www.aurigma.com/d...ththeColorManagement.htmThe code we've written is as follows: Code:
'Choose LittleCMS color management engine
img.ColorManagement.ColorManagementEngine = Aurigma.GraphicsMill.Transforms.ColorManagementEngine.LittleCms
'Assign output RGB profile for conversion
img.ColorManagement.RgbColorProfile = Aurigma.GraphicsMill.ColorProfile.FromSrgb
img.colormanagement.TransformationIntent = ColorTransformationIntent.Perceptual
'Convert to RGB
img.ColorManagement.ConvertToContinuous(Aurigma.GraphicsMill.ColorSpace.Rgb, False, img.IsExtended)
Yet when the image is saved the colours are much too bright. The attached file shows the original on the left and the converted image on the right. Any ideas on what we're doing wrong? I've tried several different TransformationIntent options but the result is the same. Thanks JamesL attached the following image(s):

James, Your image doesn't contain an embedded color profile. So, actually color management is not applied while color conversion is being made and you get wrong colors. Prior to calling img.ColorManagement.ConvertToContinuous you should do the following: Code:
if (img.ColorProfile == null)
img.ColorProfile = new ColorProfile(pathToCmykProfile);
pathToCmykProfile - file path to a predefined CMYK profile. Edited by user Thursday, May 16, 2013 8:46:18 AM(UTC)
