PDF to Image
Hi,
when I convert some PDF documents to an image (png) I get an empty image
back. Only thing I can see is this warning:
WARN org.apache.pdfbox.util.operator.pagedrawer.Invoke.process(77);
getRGBImage returned NULL
Looking into the source (1.5.0), I see this:
PDXObjectImage image = (PDXObjectImage)xobject;
try
{
image.setGraphicsState(drawer.getGraphicsState());
BufferedImage awtImage = image.getRGBImage();
if (awtImage == null)
{
log.warn("getRGBImage returned NULL");
return;//TODO PKOCH
}
...
Bug?
Not ready?
Thank you

OK, now I got it.
jai_imageio.jar must before jai_code.jar in the classpath otherwise one gets
the "getRGBImage returned NULL" message. Seems that both jars contain the
same classes but different impl?

Thanks for the feedback.

Sorry, this was nonsense, I had a typo in my classpath.
Snapshot 1.6.0 does the job now since no need for imageio any more.
Thank you

We don't have a strict roadmap. If nothing unforseen happens, it will be out
next month.

Yes, that would be the best choice. But you have to wait a couple of weeks for
the next release.

Hmmm, it worked in other cases, however the best idea is to wait for the next
release.

Hm, my app uses already jai_core.jar, jai_codec.jar and jai_imageio.jar...

The PDF works well using the current trunk. Prior versions <= 1.5.0 have to use
an additional ImageIO plugin to handle the CCITTFax-encoded image. See [1] for
further details.

I have attached the pdf. It is a TIFF wrapped by a PDF (generated by iText
1.4.1).

This is what I traced when I call convertToImage on this pdf. I used V 1.3.1
now, because I had another project where this already worked:

Without having a hand on the pdf this will be only a guess. It sounds like an
issue which should be resolved in the current trunk. Did you ever try the most
recent dev-version?
