Tilman Hausherr resolved PDFBOX-4733.
-------------------------------------
Resolution: Not A Bug
Closing this because it is not a bug. Big result images will need more memory,
as are PDFs with big images inside. The link I provided indicates some
workarounds. I was able to get it to work with {{-Xmx3g}}. Another idea
({{BigBufferedImage}}) is shown in PDFBOX-4726.

> Hi team,
>
> I'm using PDFRenderer to create image for each page of my PDF files.
> But I'm getting OutOfMemory error on some of my pdfs at some page.
>
> *I summarize my code as following:*
>
>
> {code:java}
> File pdfFile = new File(filePath);
> try(PDDocument document = PDDocument.load(pdfFile)) {
> PDFRenderer renderer = new PDFRenderer(document);
> for(int i = 0; i < document.getNumberOfPages(); i++){
> System.out.println("Rendering " + i + " th page");
> BufferedImage bufferedImage = renderer.renderImageWithDPI(i, 300);
> }
> }
> {code}
>
>
> *Attached pdf file*
> My PDf file exceeds 60MB, so I have it shared on Dropbox.
