Color Space Creation
For Adobe PDF Library v4.0 and higher, all of the color spaces may be created by the procedure
PDEColorSpaceCreate.
NOTE: A COS object is a document object, and cannot be shared between
documents. However, the PDEColorSpace created from a document-specific
COS Object is not a document object, and may be shared.
For example, to create a Calibrated Gray Scale color space, you would need the following code fragment:
Creating Calgray Color Space for Adobe PDF Library v4.0 and later
PDEColorSpace CIEGrey;
PDEGrayCalFlt CIEGreyDesc;
CIEGreyDesc.gamma = 0;
CIEGreyDesc.whitePoint.x = 0.9506;
CIEGreyDesc.whitePoint.y = 1.0;
CIEGreyDesc.whitePoint.z = 1.0890;
CIEGreyDEsc.blackPoint.x = 0.0;
CIEGreyDEsc.blackPoint.y = 0.0;
CIEGreyDesc.blakcPoint.z = 0.0;
CIEGrey = CreateColorSpace (AsAtomFromName (“CalGray”),
(PDEColorSpaceStruct *)&CIEGreyDesc);
