> Pdf to image conversion not releasing memory after conversion
> -------------------------------------------------------------
>
> Key: PDFBOX-4144
> URL: https://issues.apache.org/jira/browse/PDFBOX-4144
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing, Rendering
> Affects Versions: 2.0.8
> Environment: Apache Tomcat/8.0.33, Linux, JDK 1.8
> Reporter: Sachin Mali
> Priority: Major
>
> I have written a program that accepts pdf and convert it to image. Please see
> the below code for your reference.
> {code:java}
> ByteArrayInputStream ipStream = new
> ByteArrayInputStream(document.getFile().getBytes());
> PDDocument documentUploaded =
> PDDocument.load(ipStream,MemoryUsageSetting.setupTempFileOnly());
>
> documentUploaded.setResourceCache(new MyResourceCache());
> //Disabled a resource cache
> PDFRenderer pdfRenderer = new PDFRenderer(documentUploaded);
> int pageCounter = 0;
> for (PDPage page : documentUploaded.getPages())
> {
> BufferedImage bim = pdfRenderer.renderImageWithDPI(pageCounter,
> 300, ImageType.RGB);
> pageCounter = pageCounter + 1;
>
> // Some code here
> bim.flush();
> bim = null;
> }
> documentUploaded.close();
>
> {code}
> After/Before conversion i printed heap size used by using
> Runtime.getRuntime().totalMemory() . Also I checked top command to see
> percentage of memory used.But in both cases the memory keeps increasing after
> each conversion and does not release used memory.After tomcat restart I get
> cleaned memory.
