Hello. I get an OutOfMemoryError when running the following command:
java -Xmx2g -jar pdfbox-app-2.0.11.jar PDFToImage -dpi 300 pattern_issue_oom.pdf (Windows 10, java version "1.8.0_112") The file is available here: http://www.filedropper.com/patternissueoom It is a simplification of a real life pdf and it contains nested patterns. It is really small: 4429 bytes. Is this the expected memory usage for this pdf? Can I expect some improvements in pdfbox? Can I somehow detect this kind of pdfs and avoid rendering (i.e.: with the PDFBOX api)?
