I'm in the process of trying to determine the color space (Section 4.5
of the PDF 1.4 reference) requirements for PDFax for the first draft. I
was considering the following color spaces requirements:
Pattern -- Prohibited.
Separation -- Prohibited.
DeviceN -- Prohibited.
DeviceGray -- Required.
DeviceRGB -- Required.
DeviceCMYK -- Required.
Indexed -- Required.
CalGray -- Optional.
CalRGB -- Optional.
Lab -- Optional.
ICCBased -- Optional.
I was thinking that in the interest of keeping the number of options to
a minimum, we would limit the combinations of the optional color spaces
to just all, none, and maybe one other combination (ICCBased by itself).
Does anyone have any comments on this issue?
