The Error #3000 "Invalid PCS" raises by calling
"cmsCreateMultiprofileTransform".
If I create same kind of transformations from RGB to CMYK or from
CMYK to CMYK, there raises no error.
Is this in v1.18 or later the same?
What I do wrong and what could be a solution?
I try to simplify the code, sorry.
// Creating proof tansform without InkLimit.
Proof1_CMYK_from_XYZ_TRANSFORM := cmsCreateProofingTransform(
Input_XYZ_PROFILE, TYPE_XYZ_16,
Output_CMYK_PROFILE, TYPE_CMYK_16,
cmsCreateXYZProfile,
Intent,
INTENT_ABSOLUTE_COLORIMETRIC, 0);
PROFILE_ary[0] := cmsTransform2DeviceLink
( Proof_CMYK_from_XYZ_TRANSFORM, 0);
PROFILE_ary[1] := cmsCreateInkLimitingDeviceLink( icSigCmykData,
Limit);
// Generate proof transform with InkLimit.
Proof2_CMYK_from_XYZ_TRANSFORM := cmsCreateMultiprofileTransform(
@PROFILE_ary, 2, TYPE_XYZ_16,
TYPE_CMYK_16, Intent, 0);
Regards,
Wolfgang

Hi,
That may be a bug, but it is hard to follow the code for me. May I
ask you
to try to reproduce the issue by using icclink? That would make
easier to
uncover the source of the mistake.
Thanks for reporting.
Regards
Marti.
