Hi Roger, I'm not a c# expert, but your code seems fine. I guess the problem is elsewhere...

I need to convert 400 RGB values to Lab using a monitor profile. I use the following C# code : string Source = "Monitor.icm"; IntPtr hSource = cmsOpenProfileFromFile(Source, "r"); xform = cmsCreateTransform(hSource, TYPE_RGB_DBL, hLab2, TYPE_Lab_DBL, INTENT_ABSOLUTE_COLORIMETRIC, 0); for (int i = 0; i < 400; i++) { input[0] = R[i]; input[1] = G[i]; input[2] = B[i]; cmsDoTransform(xform, input, output, 1); L = output[0]; a = output[1]; b = output[2]; } First time through the loop I get valid Lab results. But subsequent passage through the loop always return the same Lab values? The input[] values do change as expected. When I use this code outside of a loop, it works perfect. / Roger Breton ---------------------------------------------------------------------------- -- What NetFlow Analyzer can do for you?
