I've done a bit if testing of pdfbox under the new Java 7, update 1 release, and am noticing severe image quality issues when converting a pdf to an image. Attached is the same pdf turned converted to an image under Java 6, then again with Java 7 with the same code. The Java 7 version looks pretty bad. Anyone notice an issue like this? This is with jdk 1.7 update 1 (for solaris x64, running headless). I've also tested against the latest code in svn (the images below are from the most current version). The good image below is from a recent version of the jdk 1.6 (and it has always looked good on at least jdk1.5+). To test, I used code like this: public static BufferedImage toBufferedImage(final byte[] pdfBytes, final int resolution) throws IOException { PDDocument document = null; try { document = PDDocument.load(new ByteArrayInputStream(pdfBytes)); final PDPage page = (PDPage) document.getDocumentCatalog().getAllPages().get(0); final BufferedImage result = page.convertToImage(BufferedImage.TYPE_INT_ARGB, resolution); return result; } finally { if (document != null) { document.close(); } } } And this is exported to png24 with: ImageIO.write(bufferedImage, "png", outputStream); I can create more text code and a sample pdf, but this should be reproducible on any pdf. The problem seems universal. Thanks so much, Armando   |
