Tengo una pequena problema...
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.
