              Could you give me a little more information on how you are using ICEpdf in your applications. Fore example does each request have an instance of ICEpdf's Document class or do you have some type of Document pool?

              Are you using 5.0 or 5.0.3?

              We use the version 5.0.2 and the code is :

              public static byte[][] convertPDFtoPNG(File src, float scale, int start, int end) throws Exception {

              if (!isPDF(src))

              { throw new Exception("El fichero de origen debe ser un *.pdf"); }

              Document document = new Document();

              document.setFile(src.getAbsolutePath());
              if (end == -1 || end > document.getNumberOfPages())

              { end = document.getNumberOfPages(); }

              ByteArrayOutputStream baous = null;
              BufferedImage image = null;
              byte[][] data = new byte[end - start + 1][];
              try {
              int index = 0;
              for (int i = start - 1; i < end; i++)

              { baous = new ByteArrayOutputStream(); image = (BufferedImage) document.getPageImage( i, GraphicsRenderingHints.PRINT, Page.BOUNDARY_CROPBOX, 0, scale); ImageIO.write(image, "png", baous); data[index] = baous.toByteArray(); index++; image.flush(); image = null; baous.flush(); baous.close(); }

              } finally

              { document.dispose(); }

              return data;

              }

              Closing, lack of sample file and not contact for over a year.
