High CPU load an memory usage, when converting PDF to Image
Hello!
We are running a business web application, that is using pdfbox to convert pdf-files to images, using PDPage.convertToImage().
When we try to convert the attached pdf, the CPU load of tomcat is raising and it seems, that the process hangs. The tomcat process is no more responsive and after a long while, we get an memory overflow. Also the server load is very high meanwhile.
We have seen this on pdfbox 1.8.8, 1.8.9 and 1.8.11-SNAPSHOT
Do you have an idea, how to prevent this?
Our code looks like this:
private void convertPDF2JPG(File inFile, String outFile) throws Exception {
PDDocument pdf = PDDocument.load(inFile);
List<PDPage> allPages = (List<PDPage>)pdf.getDocumentCatalog().getAllPages();
for (PDPage pdPage : allPages ) {
int resolution = 220;
BufferedImage bufferedImage = pdPage.convertToImage(BufferedImage.TYPE_INT_RGB, resolution);
Graphics2D bufImageGraphics = bufferedImage.createGraphics();
bufImageGraphics.drawImage(bufferedImage, 0, 0, null);
bufImageGraphics.dispose();
convertAnyImage2JPG(bufferedImage, new File(outFile));
}
}
Thank you very much and best regards,
Frank

Great. Thank you for your help!
For us, it would be enough to identify such a file, before calling convertToImage(), to avoid the high server load.
Do you think, there is a way to get this information out of the pdf?

Thanks. According to virustotal.com, one (Dr.Web) of 51 programs claims
that it is a virus (SCRIPT.Virus). I've send it to them for analysis. In
the meantime, I'm also trying to display that file with 2.0 and nothing
happens except my CPU heating the room. Either we have a new bug, or the
file is really very complex.
Reminds me that I have the same problem with this file:
