             Summary: Out Of Memory exception during converting PDF to PNG
                 Key: PDFBOX-3236
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3236
             Project: PDFBox
          Issue Type: Bug
          Components: Rendering
    Affects Versions: 2.0.0
            Reporter: Ilya Scherbakov
            Priority: Critical
             Fix For: 2.0.0


I use PDFBox 2.0.0 RC3 from TestComplete 10.60. My task is converting of multi-page PDF to PNG images. During code execution on the 18th page I receive error: java:lang.OutOfMemoryError: Java heap space.

Error appeared in the string:
 JavaClasses.javax_imageio.ImageIO.write_3(pdfRenderer.renderImageWithDPI_2(i, 300.0), "png", outputStream);   // error

My code is the following:

function convertPDFToImages(pdfPath, folderForImagesPath)
{
    // Opening PDF
    f = JavaClasses.java_io.File.newInstance(pdfPath);
    docObj = JavaClasses.org_apache_pdfbox_pdmodel.PDDocument.load_2(f);
    var pdfRenderer = JavaClasses.org_apache_pdfbox_rendering.PDFRenderer.newInstance(docObj);
    
    var pageObj;
    var fileToWrite;
    var numberOfPages = getNumberOfPDFPages(pdfPath);
    var outputStream;
        
    for (var i = 1; i < numberOfPages; i++)
    {        
        // Get the desired page
        pageObj = getPage(docObj, i);
        fileName = folderForImagesPath + "\\etalon_page_" + (i + 1) + ".png";
        fileToWrite = JavaClasses.java_io.File.newInstance(fileName);
        outputStream = JavaClasses.javax_imageio.ImageIO.createImageOutputStream(fileToWrite);
        JavaClasses.javax_imageio.ImageIO.write_3(pdfRenderer.renderImageWithDPI_2(i, 300.0), "png", outputStream);   // error
        outputStream.close();
    
                    
    }
    docObj.close();   // Closing PDF Document
    Log.Message("Converting of file \"" + pdfPath + "\" was finished successfully. See files like etalon_page_NNN.png in the folder \"" + folderForImagesPath + "\".");
}
