Converting a PDF into multiple JPGs with iText or other

I have the need to convert any multipage PDF file into a set of JPGs.

Since the PDF files are supposed to come from a scanner, we can assume each page just contains a graphic object to extract, but I cannot be 100% sure of that.

So, I need to convert any renderable content from each page into a single JPEG file.

How can I do this with iText?

If I can't do this with iText, what Java library can achieve this?

Thanks.

With Apache PDFBox you could do the following:

PDDocument document = PDDocument.load(pdffile);
List<PDPage> pages = document.getDocumentCatalog().getAllPages();
for (int i = 0; i < pages.size(); i++) {
  PDPage page = pages.get(i);
  BufferedImage image = page.convertToImage(BufferedImage.TYPE_INT_RGB, 72);
  ImageIO.write(image, "jpg", new File(pdffile.getAbsolutePath() + "_" + i + ".jpg"));
}

Ghostscript (available for Windows, Linux, MacOS X, Solaris, AIX,...) can convert...

  • ...from input formats: PDF, PostScript, EPS and AI
  • ...into output formats: JPEG, TIFF, PNG, PNM, PPM, BMP, (and more).

(The ImageMagick mentioned above doesn't do the conversion on its own -- it uses Ghostscript under the hood, as do many other tools.)

You can also use Sun's PDF-Renderer and JPedal does PDF to image (low and high res.

ICEpdf - http://www.icepdf.org/ - has an open source entry version which should do what you need.

I believe the primary difference between the open source version and the pay-for version is that the pay-for has much better font support.
