OutOfMemory when optimizing images

[GuiPATRY]

Hello
using the "standard" code to optimize images

Code: Select all

      PdfPageCollection pages = document.getPages();
      for (int i = 0; i < pages.getCount(); i++) {
         PdfPageBase page = pages.get(i);
         if (page != null) {
            PdfImageInfo[] infos = page.getImagesInfo();
            if (infos != null) {
               for (PdfImageInfo pdfImageInfo : infos) {
                  page.tryCompressImage(pdfImageInfo.getIndex());
               }
            }
         }
      }


I get an OutOfMemory exception when using some files with a lot of images.
The runtime also increase in a clearly non-linear fashion...

Thanks in advance

Hello Guillaume,

Thanks for your inquiry.

Parsing and processing images will take a lot of resources. I suggest that you first try to increase the maximum memory limit of the JVM so that the program has more resources to use and thus reduce the situation of insufficient memory. If the issue still exists, could you please provide us with some test pdfs to help us better investigate and optimize this issue? Thanks in advance for your assistance.
