ICC profiles are available in different versions. Which profile versions are allowed to use depends
on the output PDF version:
PDF Version
ICC Specification Version
ICC Profile Version Number
PDF 1.3
3.3 or earlier
PDF 1.4
ICC.1:1998-09 and its addendum
PDF 1.5
PDF 1.6
PDF 1.7
Please note that neither PDF/A-1 nor PDF/X-1 and PDF/X-3 support ICC profile major versions
higher than 2. The functions CreateICCBasedColorSpace() and AddRenderingIntent() check the
profile version only if the output version was set to a PDF/A or PDF/X compatible version (see
ICC profiles are available for different input color spaces such as DeviceGray, DeviceRGB,
DeviceCMYK, or Lab. Color values must be defined in the very same as for the corresponding
device color spaces.
Non-device color spaces cannot be used for interactive objects such as annotations or form fields.
The active color space must always be changed to a device color space before creating interactive
objects; see SetColorSpace(). Note also that annotations support DeviceRGB only. Form fields
support DeviceGray, DeviceRGB, and DeviceCMYK.
Use the function SetExtColorSpace() to activate the color space in the graphics state. To set a color of
an ICC-based color space convert the color value to a 32 bit integer in the very same way as for
DeviceGray, DeviceRGB, or DeviceCMYK depending on the base color space and pass the resulting
color value to SetFillColor(), SetStrokeColor(), or SetColors().
Return values:
If the function succeeds the return value is the color space handle, a value greater or equal zero. If
the function fails the return value is a negative error code.
