             Summary: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
                 Key: PDFBOX-3573
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3573
             Project: PDFBox
          Issue Type: Bug
          Components: Parsing, Utilities
    Affects Versions: 2.0.3
         Environment: Ubuntu 15.10
            Reporter: Dmitri Russu


I try to get Images from an PDF file, file pages are images, total size of PDF file is about 1MB

Code I run is next

	public static void testExtractImages() throws Exception {

		File resource = new File("test/t1_edited.pdf");

		PDDocument document = PDDocument.load(resource);
		int page = 1;
		for (final PDPage pdPage : document.getPages())
		{
			final int currentPage = page;
			PDFGraphicsStreamEngine pdfGraphicsStreamEngine = new PDFGraphicsStreamEngine(pdPage)
			{
				int index = 0;

				@Override
				public void drawImage(PDImage pdImage) throws IOException
				{
					if (pdImage instanceof PDImageXObject)
					{
						PDImageXObject image = (PDImageXObject)pdImage;
						File file = new File("test/", String.format("10948-new-engine-%s-%s.%s", currentPage, index, image.getSuffix()));
						ImageIOUtil.writeImage(image.getImage(), image.getSuffix(), new FileOutputStream(file));
						index++;
					}
				}

				@Override
				public void appendRectangle(Point2D p0, Point2D p1, Point2D p2, Point2D p3) throws IOException { }

				@Override
				public void clip(int windingRule) throws IOException { }

				@Override
				public void moveTo(float x, float y) throws IOException {  }

				@Override
				public void lineTo(float x, float y) throws IOException { }

				@Override
				public void curveTo(float x1, float y1, float x2, float y2, float x3, float y3) throws IOException {  }

				@Override
				public Point2D getCurrentPoint() throws IOException { return null; }

				@Override
				public void closePath() throws IOException { }

				@Override
				public void endPath() throws IOException { }

				@Override
				public void strokePath() throws IOException { }

				@Override
				public void fillPath(int windingRule) throws IOException { }

				@Override
				public void fillAndStrokePath(int windingRule) throws IOException { }

				@Override
				public void shadingFill(COSName shadingName) throws IOException { }
			};
			pdfGraphicsStreamEngine.processPage(pdPage);
			page++;
		}
	}
