[jira] [Created] (PDFBOX-2313) ExtractImages finds never-rendered images

John Hewson created PDFBOX-2313:
-----------------------------------

             Summary: ExtractImages finds never-rendered images
                 Key: PDFBOX-2313
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2313
             Project: PDFBox
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 2.0.0
            Reporter: John Hewson


The file from PDFBOX-2101 is still causing unexpectedly high memory use with ExtractImages when compared to PDFToImage. Given that PDFToImage uses the same caching strategy, it's not really a caching issue, though we might still want to think about that.

The PDF contains 55 images on the first page which are never rendered and ExtractImages runs out of memory trying to extract them all. Given that PDFs often contain junk like this, I suggest that ExtractImages only extract images which are actually drawn to the page at some point.
