Hello,
A PowerPoint slide show file (PPSX) has caused the PDF rendering code hang for a few hours and subsequently crashed.
Conversion code:
//Load the custom font directory fonts
FontsLoader.loadExternalFonts(fontDir);
logger.debug(“fonts loaded.”);
Integer detectedFormat = PresentationFactory.getInstance().getPresentationInfo(fileName).getLoadFormat();
logger.debug("detected PPT file format: " + detectedFormat);
com.aspose.slides.LoadOptions lo = new com.aspose.slides.LoadOptions();
lo.setLoadFormat(detectedFormat);
Presentation pres = new Presentation(contentStream, lo);
logger.debug("New pres object created.");
pres.save(targetFileName, SaveFormat.Pdf, pptPdfSaveOptions);
Execution log (note the time stamps). Each step takes huge amount of time:
*Font loading - 7 minutes
*format detection - 5 minutes
*loading presentation object - 24 minutes
*saving presentation object to PDF - several hours, with subsequent crash.
Please investigate. The source file attached.
Thanks,
Dmitry

Our product team has investigated the issue on their end. We have not find any performance problems related issue directly linked to Aspose.Slides for Java. The performance is reduced on your end, because you have used Virtual Machine and also obtained Head Dump and GC settings are not optimal. All this together seriously reduces performance in general.
