Hi,
I'm in the process of migrating from ImageMagick to GraphicsMagick and am
looking at using colour conversions using profiles and LCMS2
If I convert a CMYK embedded image to Lab I actually get a corrupted RGB image.
image.RenderingIntent=1 //absolute
image.iccColorProfile = new GMBlobMBS(lp.SaveProfileToString)
#if DebugBuild
dim ProfileBlob as GMBlobMBS = Image.iccColorProfile
dim ProfileData as string = ProfileBlob.CopyString
dim cm as LCMS2ProfileMBS =
LCMS2ProfileMBS.OpenProfileFromString(ProfileData)
dim name as string = cm.Name
image.write(SpecialFolder.Desktop.Child("calculate_preview_lab.tif"))
#endifLABColorspace
If I convert directly to RGB from CMYK I get an acceptable (but not colour
accurate enough) result.
In the readme I see that:
LABColorspace = 14 (LAB colorspace not supported yet other than via lcms)
What does this mean?
