Thanks for the reply. I totally had to do the nill check where you pointed
out. But that does not solve the problem either.
Here's the new code:
extern "C" __declspec(dllexport) int ToneMapping(int* intPtr, int size,
char* icc1, int len_icc1, char* icc2, int len_icc2)
{
char* icc_1 = NULL;
char* icc_2 = NULL;
icc_1 = (char*)malloc(sizeof(char)*len_icc1 +1);
icc_2 = (char*)malloc(sizeof(char)*len_icc2 +1);
if(icc_1 == NULL || icc_2 == NULL) return -1;
memcpy(icc_1, icc1, len_icc1);
memcpy(icc_2, icc2, len_icc2);
cmsHPROFILE hInProfile = NULL;
cmsHPROFILE hOutProfile = NULL;
cmsHTRANSFORM hTransform = NULL;
hInProfile = cmsOpenProfileFromFile(icc_2, "r");
hOutProfile = cmsOpenProfileFromFile(icc_1, "r");
if(hInProfile == NULL || hOutProfile == NULL) return -2;
hTransform = cmsCreateTransform(hInProfile,
TYPE_BGR_8,
hOutProfile,
TYPE_BGR_8,
INTENT_PERCEPTUAL, 0);
if(hTransform == NULL) return -3;
cmsDoTransform(hTransform, intPtr,
intPtr,
size);
free(icc_1);
free(icc_2);
free(hInProfile);
free(hOutProfile);
free(hTransform);
return 1;
}
it's first call returns 1 which means it works fine. But the next calls
return -2 which means "cmsOpenProfileFromFile" gives NULL. Do you know why
it happens?
