Hi,
I have some profiles, with a bit wobbly gamma...
I'd like to write a simple program which read a source profile
then smoothes all three gamma curves, and then writes the
complete resulting profile to a destination file.
I've already fiddled a bit with some code:
#include "lcms.h"
int main(void)
{
cmsHPROFILE hProfile;
hProfile = cmsOpenProfileFromFile("test.icc", "r");
LPGAMMATABLE lpRedGamma;
LPGAMMATABLE lpGreenGamma;
LPGAMMATABLE lpBlueGamma;
lpRedGamma = cmsReadICCGamma(hProfile, icSigRedTRCTag);
lpGreenGamma = cmsReadICCGamma(hProfile, icSigGreenTRCTag);
lpBlueGamma = cmsReadICCGamma(hProfile, icSigBlueTRCTag);
cmsSmoothGamma(lpRedGamma, 10);
cmsSmoothGamma(lpGreenGamma, 10);
cmsSmoothGamma(lpBlueGamma, 10);
cmsCloseProfile(hProfile);
cmsFreeGamma(lpRedGamma);
cmsFreeGamma(lpGreenGamma);
cmsFreeGamma(lpBlueGamma);
return 0;
}
Please note I'm not an experienced C programmer. As you might see
from the above code, I have managed to load an ICC Profile, and extracted
all three gamma curves from it, and then smoothed them.
But, how do I reintegrate these gamma curves back into the profile, and
write the profile back to disk?

Pascal de Bruijn
