[jira] [Created] (PDFBOX-2323) More flexible image caching

John Hewson created PDFBOX-2323:
-----------------------------------

             Summary: More flexible image caching
                 Key: PDFBOX-2323
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2323
             Project: PDFBox
          Issue Type: Improvement
          Components: PDModel, Rendering
    Affects Versions: 2.0.0
            Reporter: John Hewson
            Priority: Minor


Image caching in PDImageXObject can cause very high memory usage which has resulted in issues PDFBOX-2313, PDFBOX-2310, PDFBOX-2101. Images are just so large that the current "on size fits all" caching isn't working well.

Pushing responsibility for caching down to callers of PDImage#getImage() would allow for use-case specific caching strategies, for example PDFRenderer could cache small images for the duration of a document being rendered, rather than having to re-create the PDImageXObject again for every page on which it appears. Likewise caching of large images could be limited to a single page, or not at all.
