> Wrong color of uncolored tiling pattern
> ---------------------------------------
>
> Key: PDFBOX-4627
> URL: https://issues.apache.org/jira/browse/PDFBOX-4627
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.16
> Reporter: Jiri Kunhart
> Assignee: Tilman Hausherr
> Priority: Major
> Labels: tilingpattern
> Fix For: 2.0.33, 3.0.4 PDFBox, 4.0.0
>
> Attachments: after_fix.png, before_fix.png, uncolored_tiling_pattern.patch, uncolored_tiling_pattern.pdf
>
>
> The attached pdf file with uncolored tiling pattern is rendered wrongly (see "before_fix.png"). The problem is that pattern stream contains
> /DevGrayCS cs
> which overwrites PDPattern color space stored in PDGraphicsState#nonStrokingColor. I did a small fix which ignores all settings of color space inside of uncolored tiling pattern stream and the result seems to be good (see "after_fix.png").
> Note: the pattern in the png file looks diferently than in the original pdf file, but this should be handled probably in the other issue.
