krilla: PDF/A ledgers state DeviceN and the print output intent
Patch 06 records that DeviceN fails export under PDF/A-1 to -3 (its tint transform is PostScript) and is written under PDF/A-4; patch 08 records the second output intent and the caller's CMYK destination profile.

- krilla only uses RGB for output intents. 🟢
|
||||
- krilla writes one output intent, or with `SerializeSettings::output_intent` two
|
||||
(`GTS_PDFA1` and `GTS_PDFX`) that name the same destination profile object. 🟢
|
||||
- krilla uses the sRGB display profile for the output intent, or the CMYK profile given in
|
||||
`SerializeSettings::output_intent`. 🟢
|
||||
- krilla checks only that a profile given in `SerializeSettings::output_intent` has four
|
||||
components; that it is an output (`prtr`) profile is up to the caller. 🟣
|

|
||||
### 6.2.4 Colour spaces
|
||||
- krilla only uses device-independent colors in this export mode. 🟢
|
||||
- krilla uses compatible ICC profiles. 🟢
|
||||
- krilla fails export if overprint mode 1 is combined with fill or stroke overprint, since
|
||||
all CMYK is ICCBased in this mode. 🟢
|
||||
- krilla never uses CMYK profiles as the destination profile. 🟢
|
||||
- krilla uses a CMYK profile as the destination profile only when
|
||||
`SerializeSettings::output_intent` gives one. 🟢
|
||||
- krilla does not use device color spaces in this mode. 🟢
|
||||
- krilla ensures the Alternate space in Separation color spaces obeys the restrictions
|
||||
in the applicable clauses 🟢
|
||||
- krilla does not support DeviceN color spaces. 🔵
|
||||
- krilla writes DeviceN color spaces with the CMYK ICC profile as their alternate in this
|
||||
mode. Each spot colorant is also listed under `/Colorants` as a Separation space with the
|
||||
same alternate, and a space mixing spot and process colorants is `/Subtype /NChannel`.
|
||||
The tint transform is a PostScript calculator function, which PDF/A-4 allows. 🟢
|
||||
- krilla fails export if a Separation colorant is associated with multiple different
|
||||
fallback color spaces 🟢
|
||||
fallback color spaces, a DeviceN spot colorant's alternate included 🟢
|
||||
- krilla manages the `tintTransform` function and will always write the same function for
|
||||
the same color space 🟢
