The question now becomes which mis-matched items are preventing processing.
> 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
> Priority: Critical
> Attachments: broken.txt, fixed.txt, 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.
