--------------------------------------
Summary: DeviceN/NChannel Seperation fails for rgb
Key: PDFBOX-5370
URL: https://issues.apache.org/jira/browse/PDFBOX-5370
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 2.0.25, 2.0.26, 3.0.0 PDFBox
Reporter: Maruan Sahyoun
Attachments: NChannel-Pantone-1.BMP, NChannel-Pantone-1.PNG,
NChannel-Pantone.bmp, NChannel-Pantone.pdf, NChannel-cmyk-1.BMP,
NChannel-cmyk-1.PNG, NChannel-cmyk.bmp, NChannel-cmyk.pdf, NChannel-rgb-1.BMP,
NChannel-rgb-1.PNG, NChannel-rgb.bmp, NChannel-rgb.pdf
The files NChannel-xx.pdf use different color modes for separation which is
described in chapter 10.8.3 of the PDF spec. The matching .bmp files show the
expected results. The -1.BMP and -1.PNG files show the results generated by
PDFBox trunk (2.0 is the same result).
As can be seen the results for cmyk and Pantone are fine/close with the rgb
rendering failing.
