Tilman Hausherr commented on PDFBOX-2340:
-----------------------------------------
I'd like to have a segment on rendering in the cookbook. Here's an example that
I hope is good for beginners:
{code}
String filename = "YOURFILENAMEHERE.pdf";
// open the document
PDDocument doc = PDDocument.loadNonSeq(new File(filename), null);
// old parser
// PDDocument doc = PDDocument.load(new File(filename));
// if (doc.isEncrypted())
// {
// // some files are encrypted with the empty password
// StandardDecryptionMaterial sdm = new
StandardDecryptionMaterial("");
// doc.openProtection(sdm);
// }
boolean b;
List<PDPage> pages = doc.getDocumentCatalog().getAllPages();
for (int p = 0; p < pages.size(); ++p)
{
// RGB image with 300 dpi
BufferedImage bim =
pages.get(p).convertToImage(BufferedImage.TYPE_INT_RGB, 300);
// save as PNG with default metadata
b = ImageIO.write(bim, "png", new File("rgbpage" + (p+1) + ".png"));
if (!b)
{
// error handling
}
// B/W image with 300 dpi
bim = pages.get(p).convertToImage(BufferedImage.TYPE_BYTE_BINARY,
300);
// save as TIF with dpi in the metadata
// PDFBox will choose the best compression for you - here: CCITT G4
// you need to add jai_imageio.jar to your classpath for this to
work
b = ImageIOUtil.writeImage(bim, "bwpage-" + (p+1) + ".tif", 300);
if (!b)
{
// error handling
}
}
doc.close();
{code}
