-----------------------------------------
1.8 displays the RGB file properly?!
> 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
> Priority: Major
> 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.
> The PDFs and expected results have been provided by Hans Bärfuss, PDF Tools AG. Thank you for contributing the samples.
