PSOutputDev/pdftops: add more options to control color handling during rasterization
This merge request consists of three commits:
- The first commit is the main contribution. It adds the
-processcolorformat
and-processcolorprofile
options topdftops
. The former sets the splash bitmap type during rasterization, whereas the latter sets the corresponding ICC profile. -
The second commit just introduces theWas introduced in !576 (merged)-rasterize
flag topdftops
, which makes testing these changes a lot easier and is probably of independent use. - The last commit activates
-overprint
by default if the splash bitmap type is CMYK8 and the language level is greater or equal to 2. This behavior is consistent with the assumption that CMYK printing devices probably respect the overprint operators and that PSOutputDev would emit the overprint operators for level>=2.
Thx for reviewering
