Hi,


we are trying to convert the first and only page if this PDF to an image, but Aspose gets stuck in an infinite loop.

With the following code:

final PdfConverter converter = new PdfConverter();
converter.bindPdf(new ByteArrayInputStream(bytes));
converter.setStartPage(1);
converter.setEndPage(1);
converter.doConvert();

final ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
converter.getNextImage(outputStream);

Any advice? getNextImage() never seems to return, at least not within 20-30 minutes.

We have now been forced to perform all image conversions in separate worker threads, that we attempt to stop() (Thread#stop()) if Aspose doesn’t return within a specified timeout. But this is an enormous hack.


It’s of course accetable that Aspose can’t convert all PDFs, but to get stuck in an infinite loop is not.
