Michael Klink commented on PDFBOX-4627:
---------------------------------------
Please no qick-fix, though - PDFBox is not only used for rendering but also for
validation, and in such use cases the invalid instructions *must not be
dropped*!
> 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
> Priority: Major
> 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.
