Tilman Hausherr updated PDFBOX-1206:
------------------------------------
Attachment: converttoimage.pdf-1.png
Here's what I get, although I used RGB and not ARGB. Are you still having the
problem?
> PdfToImage no longer works as expected with jdk/java 7; image quality problem
> -----------------------------------------------------------------------------
>
> Key: PDFBOX-1206
> URL: https://issues.apache.org/jira/browse/PDFBOX-1206
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 1.6.0, 1.7.0
> Environment: All (tested on OS X and Solaris but believe it affects
> all platforms), tested java 7 update 1 & update 2
> Reporter: Armando Singer
> Labels: convertToImage, image
> Attachments: converttoimage.pdf-1.png

>
> I've done a extensive testing of pdfbox under the new Java 7, update 1 &
> update 2 releases, 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.
> This is with jdk 1.7 update 1 & 2 (for solaris x64, running headless, and OS
> X running Java 7 preview update 2 with default with no addition vm args to
> the default java command). 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:
> import java.awt.image.BufferedImage;
> import java.io.File;
> import java.io.IOException;
> import javax.imageio.ImageIO;
> import org.apache.pdfbox.pdmodel.PDDocument;
> import org.apache.pdfbox.pdmodel.PDPage;
> public final class PdfToImageTest {
> public static BufferedImage toBufferedImage(final String pdfFile, final int
> resolution)
> throws IOException {
> PDDocument document = null;
> try {
> document = PDDocument.load(pdfFile);
> 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();
> }
> }
> }
> public static void main (String[] args) throws IOException {
> ImageIO.write(toBufferedImage(args[0], 108), "png", new File(args[1]));
> }
> }
