The maximum page size is 14400x14400. This is a PDF implementation limit. ----- Original Message ----- From: "Alex Greif" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, August 03, 2005 8:47 AM Subject: [iText-questions] large image problem
Hi, my problem is the following: I have a picture in 72 dpi (width=2560px height=1920px) and want to create a scaled result that is larger than the original image and uses interpollation. the original image has a width/height ratio of 4/3, and the PDF document should have the same size as the resulting image I use the following code: // this will be the resulting size float width = 20670f; float height = width * 3/4; Rectangle pageSize = new Rectangle(width, height); Document document = new Document(pageSize); document.setMargins(0, 0, 0, 0); PdfWriter.getInstance(document, response.getOutputStream()); document.open(); byte[] origContent = IOUtil.getBytesFromFile(pictureFile); com.lowagie.text.Image image = Image.getInstance(origContent); image.setInterpolation(true); float ratio = width/image.width(); image.scaleAbsolute(width, image.height()*ratio); document.add(image); ... the scaling works fine for small images that will have a width of 5000px or 13000px but fails in this case with 21000px. the java code finishes without throwing any exceptions but the pdf page is completely blank. I know, scaling from 2560px to 21000px is not easy but in a further process the pdf will be used to print a 300 dpi image. is this a bug or some sort of overflow problem in the scaling algorithm? Any help is appreciated. Thanks, Alex. ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
