Hello, I've used the attached profile with Graphics Mill. Image should render with almost no color - warm black. Works fine in Photoshop with perceptual intent. I can't find any reference to bitmap.Data.ColorManagement.Intent in help files. My goal is to simulate Photoshops Proof setup preview. Advice? thanks, bv

Try these DLLs: http://www.aurigma.com/Download...aphicsMill20DllsOnly.zipIt is based on Little CMS color management engine rather than on Microsoft ICM (which works incorrectly). As for Intent property, it represents the same color transformation intents as in Photoshop. It takes the following constants: RenderingIntentMatch = 8, RenderingIntentGraphic = 1, RenderingIntentProof = 2, RenderingIntentProofBPC = 16, (proof + black point compensation option) RenderingIntentPicture = 4

Before installing new dlls, the following code displayed a difference in previews of an image. With the new dlls, I see no difference in the way the image displays. Is there another way to display the image with a profile? Code: var bmp = Server.CreateObject("GraphicsMill.Bitmap");
bmp.LoadFromFile(Server.MapPath('image.jpg'));
bmp.Data.ColorManagement.IsEnabled = true;
bmp.Data.ColorManagement.DataProfile = Server.MapPath('a1998.icc');
bmp.Data.ColorManagement.RgbProfile = Server.MapPath('a1998.icc');
bmp.Data.ColorManagement.TargetProfile = Server.MapPath('myprofile.icc');
bmp.Data.ColorManagement.Intent = 4; //perceptual
bmp.Data.ConvertTo24bppRgb();
bmp.Data.SaveToStream(Response);

This is a correct behavior. Your input color profile (DataProfile) is the same as your output profile (RgbProfile). That's why transformation occurs between the same color spaces and the image is not changed anyhow. You can compare it with Photoshop. To set input profile follow these steps: - Open an image.
- Go to Image -> Mode -> Assign Profile
- Choose the color profile from drop down list. If you do not see your profile in this list, put it to C:\WINDOWS\system32\spool\drivers\color\
To set output profile follow these steps: - Go to Edit -> Color Settings
- Choose the RGB profile (or whatever color space you need) in the Working Spaces groupbox.
- In Conversion Options groupbox you can play with intent.
