covert to Image is very slow

[Antonio González]

Hi

When i convert a PDF file a Image is very slow 4 o 5 secs.

my code is


String fichero = "C:\\guiaalfresco.pdf";
PDDocument pdfDocument= null;
try {
File file = new File(fichero);
pdfDocument = PDDocument.load(file);
List pages = pdfDocument.getDocumentCatalog().getAllPages();
if (pages.size()>0){
// Captura la primera página del PDF
PDPage page = (PDPage) pages.get(0);
// Convierta la página PDF a Image
BufferedImage image = page.convertToImage(BufferedImage.TYPE_INT_BGR,200 );
pdfDocument.close();
 File outputfile = new File("c:\\saved.png");
  BufferedImage imagen=resizeImage(image, 200);
  ImageIO.write(imagen, "png", outputfile);
}
} catch (IOException e) {
e.printStackTrace();
}
