Jiri Kunhart commented on PDFBOX-4627:
--------------------------------------
[~tilman] This pdf file was created by Amyuni PDF Converter and originally
contains many objects, I deleted all personal data and left only the
problematic pattern object.
It is not only about Adobe Reader, but I tried also Foxit Reader and it shows
it also well, without any error. Also preflight in Adobe Pro doesn't report any
error If I do syntax check. I read PDF Reference fifth edition and I didn't
find exactly the sentence mentioned by [~mkl], there is only written this: "The
pattern’s content stream does not explicitly specify
any colors; it can paint an image mask (see “Stencil Masking” on page 320) but
no other kind of image. " And this sounds not so strictly to me.
> 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.
