Tilman,
Thanks that was a big help.
Here is a short Groovy Script the "before" and "after" appear to show that only
the appropriate Named Separations are modified.
String inFile = "e:/testPDFs/_VarnishDiecutCrease.pdf"
Path fileLocation = Paths.get(inFile);
List<String> SeparationList = ["VARNISH", "Crease"]
byte[] pdfHandle = Files.readAllBytes(fileLocation)
PDPage pdPage = getPDPage(pdfHandle, 0)
PDResources pdResources= getPageResources(pdPage)
COSDictionary pdResDict = pdResources.getCOSObject()
COSDictionary ColorSpace = pdResDict.getItem(COSName.COLORSPACE)
ColorSpace.keySet().forEach({
This works but there's an easier way in 2.0, from the resources you can
get the colorspace names, and from the name you can get the colorspace.
But your general strategy works only on the first level (this is OK if
you created these images yourself). Colorspaces can also be in images,
in the resources of form XObjects, tiling patterns and smasks.
In theory they could also be in the form xobjects of widget annotations
but I've never seen this.

PDColor color = pdPage.getResources().getColorSpace(it).getInitialColor()
PDSeparation SeparationSpace = color.getColorSpace()
if (SeparationList.contains(SeparationSpace.getColorantName())) {
COSArray cs = SeparationSpace.getCOSObject()
cs.set(1, COSName.getPDFName("XXXX"))
}
} )

AFAIK the name isn't used, so you could do something like
sepCS.getCOSObject().set(1, COSName.getPDFName("TANZONE 12345 ABC"));

Hello,
Does any one have sample code of how to change the name of separation in a PDF? For example I have
"VARNISH" and "LAK" separations in some of my PDFs and I'd like to change them to, say,
"Varnish".
I was able to enumerate all of the Separations in my test PDF using code from
here. While that example also shows how to use a Spot/Separation Colour in a
drawing operation, I just need to rename the separation and then save the PDF
with the modified colourspace. I don't want, or need, to modify the (CMYK)
values of the separation.
Any ideas before I start digging around at the COS Level?
Thanks in advance.

Does PDFBox Support Spot Colors and Separations?
I am interested in using PDFBox for a project that requires being able to
specify spot colors and color separati... | |
