-------------------------------------------------------------------
[~jahewson] Do you remember why you removed setAlternateColorSpace() and
setTintTransform() in PDDeviceN in PDFBOX-1893 / rev 1570086, but kept
setColorantNames() and setAttributes() in the trunk? It means we have two
"easier to understand" methods, but these are worthless if we don't have the
other two. To create a DeviceN colorspace, the user would have to pass a fully
initialized COSArray to the constructor, instead of constructing an empty
object and initialize it later (as is favoured e.g. in the spring framework).

[~jahewson] Do you remember why you removed setAlternateColorSpace() and

setAttributes() in the trunk? It means we have two "high level" methods, but

> 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
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Labels: DeviceN
>
> 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.
