-----------------------------------------
There is a log output:

Info [TilingPaint] width: 6857.7163, height: -3946.014
Info [TilingPaint] XStep: 4913.0, YStep: 2827.0

Info [TilingPaint] concatenated matrix:

Try setting the pdfbox.rendering.tilingpaint.maxedge property to 7000 and it
works. However you'll need more memory. There is a huge image in that file used
for this pattern of which only a small part is actually used.

> Hi Team,
> We are using PDF to Image conversion to generate images of PDF pages and
> recently we saw an issue wherein the converted image has a different
> background image as compared to what actually exists in the PDF. This issue
> is reproducible locally and we are unable to figure out the root cause. I
> have attached the original PDF as well as the generated image to this ticket.
> Can you please help with this?
> Locally we are able to reproduce using:
> {code:java}
> java -jar pdfbox-app-2.0.29.jar PDFToImage -imageType jpg -page 8
> wrong_image_conversion.pdf {code}
