Subject [jira] [Created] (PDFBOX-4326) PDF with JPEG2000 image can't be rendered
Date Sat, 29 Sep 2018 11:44:00 GMT
Tilman Hausherr created PDFBOX-4326:
---------------------------------------

             Summary: PDF with JPEG2000 image can't be rendered
                 Key: PDFBOX-4326
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4326
             Project: PDFBox
          Issue Type: Bug
          Components: Rendering
    Affects Versions: 2.0.11
            Reporter: Tilman Hausherr
            Assignee: Tilman Hausherr
             Fix For: 2.0.13, 3.0.0 PDFBox
         Attachments: PDFJS-10026.jp2, PDFJS-10026.pdf

There is an EOF exception:
{noformat}
    java.io.EOFException
    at javax.imageio.stream.ImageInputStreamImpl.readBits(ImageInputStreamImpl.java:687)
    at org.apache.pdfbox.pdmodel.graphics.image.SampledImageReader.fromAny(SampledImageReader.java:523)
    at org.apache.pdfbox.pdmodel.graphics.image.SampledImageReader.getRGBImage(SampledImageReader.java:217)
    at org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject.getImage(PDImageXObject.java:418)
    at org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject.getImage(PDImageXObject.java:400)
    at org.apache.pdfbox.rendering.PageDrawer.drawImage(PageDrawer.java:1021) 
{noformat}
The EOF exception is because SampledImageReader expects a stream that is 3x longer than actually
appears, because the colorspace is said to have 3 colors instead of 1. This is because the
plugin returns an image with IndexColorModel which references three colors.

There are two ways to solve this and both worked: the slower is to convert to RGB which requires
another change when reading the raster (because the raster is now made if intergers), the
faster is to force a gray colorspace. I use the later but keep the change I made in passing
the raster, we may need it some day.

I'm making the change only for the trunk for now, and to the 2.0 branch after release of 2.0.12.
