---------------------------------------
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

javax.imageio.stream.ImageInputStreamImpl.readBits(ImageInputStreamImpl.java:687)

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.
