mt created XGC-134:
----------------------
Summary: Some PNGs are rendered incorrectly (Regression 2.7 -> 2.8)
Key: XGC-134
URL: https://issues.apache.org/jira/browse/XGC-134
Project: XMLGraphicsCommons
Issue Type: Bug
Components: general
Affects Versions: 2.8
Environment: Java 17.0.5 (Adoptium Temurin) on Windows x64.
Reporter: mt
Attachments: xgc_2.7_correct-1.png, xgc_2.8_wrong-1.png
After upgrading our application from FOP 2.7 to FOP 2.8 we noticed that some
PNG files are not rendered correctly in the PDF. While I initially thought this
was a problem in FOP, I can reproduce this with FOP 2.7 + XGC 2.8, so I guess
it must be an issue in XGC 2.8 .
Unfortunately I can't share the exact PNG file because it contains the logo of
one our customers. When I try to modify the PNG in any way, I can't reproduce
it anymore. I also couldn't find another PNG to reproduce this with.
Basically the PNG is rendered 3 times horizontally and a black bar appears
below the 3 images. I attached a comparison between XGC 2.7 and XGC 2.8 . These
are (obviously modified) screenshots of the PDF generated by FOP.
There were hardly any changes between XGC 2.7 and 2.8. Looks like this may be
related to XGC-132 ?
This is with Java 17.0.5 (Adoptium Temurin) on Windows x64.
