Tilman Hausherr updated PDFBOX-4326:
------------------------------------
Description:
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 JPEG2000 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.
