------------------------------------
Summary: 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
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.
