    Resolution: Duplicate

Duplicate of PDFBOX-1752. I've improved the documentation at 
https://github.com/apache/pdfbox-docs/blob/master/content/2.0/dependencies.md
but this will take effect only with the next website update.

> Hi team,
> We noticed a logo image appeared weirdly after performing a PDF to image conversion. The API we used is something like: 
> {code:java}
> PDFDocument document = PDDocument.load(xxx); 
> PDFRenderer renderer = new PDFRenderer(document);  
> renderer.renderImageWithDPI(0, dpi, ImageType.RGB); {code}
> The original pdf and the processed output image is attached to the ticket.
> The pdfbox version we are using is 2.0.27
> The original logo in the pdf:
> !image-2023-08-10-22-50-55-900.png|width=213,height=124!
> After processing:
> !image-2023-08-10-22-51-25-859.png|width=212,height=151!
