The issues you have found earlier (filed as PDFJAVA-41255) have been fixed in Aspose.PDF for Java 23.5.

I downloaded aspose-pdf-23.5 and tried the same source and sample PDF that I provided to you when I opened the issue. The issue is not resolved. The program uses 5 GB of memory and 100% cpu and never completes. At least it has not completed so far and it has been running two hours.

Why was this issue closed?

We have optimized the process and now 2.5 GB (-Xmx2560M) of RAM is enough for the successful execution of the code.

In addition, you need to enable swap: MemoryExtender.setSwapEnabled(true);

MemoryExtender.setSwapEnabled(true);
Document pdfDocument = new Document(dataDir + "QwuA2vRdX9.pdf");
for (Page page : pdfDocument.getPages()) {
 int number = page.getNumber();
 java.io.OutputStream imageStream = new java.io.FileOutputStream(dataDir + "Converted_Image_"+page.getNumber()+".png");
 com.aspose.pdf.devices.Resolution resolution = new com.aspose.pdf.devices.Resolution(100);
 com.aspose.pdf.devices.PngDevice pngDevice = new com.aspose.pdf.devices.PngDevice(resolution);
 pngDevice.process(page, imageStream);
 imageStream.close();
}
