Tilman Hausherr commented on PDFBOX-2734:
-----------------------------------------
Done. I haven't created a third constructor because the other colorspaces don't
have it either and I don't see this as a high priority.
What I also haven't done, but would like to get from a user, is a sample
program. Like what Floris did but with a real type 4 function, e.g. to convert
from Hexachrome to CMYK. (The example at
http://partners.adobe.com/public/developer/en/ps/sdk/TN5604.DeviceN_Color.pdf
didn't work, probably because only a subset of PS is supported)

> Key: PDFBOX-2734
> URL: https://issues.apache.org/jira/browse/PDFBOX-2734
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.8, 1.8.9, 2.0.0
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Labels: DeviceN
> Fix For: 1.8.10, 2.0.0
>
>
> Reported by Floris in the user mailing list. His PDF didn't have the
> attributes:
> {code}
> 6 0 obj
> <<
> /Cs1 /DeviceGray
> /Cs2 /DeviceN
> >>
> endobj
> {code}
> Reasons:
> - local array overwrites base array
> - getCOSObject returns name instead of array
> - setAttributes inflates the array too much (likely accidentally introduced
> in rev 1429524)
> PDF after the fix:
> {code}
> 6 0 obj
> <<
> /Cs1 /DeviceGray
> /Cs2 [/DeviceN [/Cyan /Magenta /Yellow /Black /Orange /Green]
> /DeviceCMYK 8 0 R 9 0 R]
> >>
> endobj
> {code}
> One of the bugs is also in the trunk, I will test this later.
