Hi all,
Our TIFF mediafilter has stopped working. I have tif, tiff, TIF, and
TIFF extensions associated with the TIFF bitstream format in the
registry. In dspace.cfg, I have added TIFF to the list of formats
filtered by both the JPEGFilter and the BrandedPreviewJPEGFilter:
filter.org.dspace.app.mediafilter.JPEGFilter.inputFormats = BMP, GIF,
JPEG, image/png, TIFF
filter.org.dspace.app.mediafilter.BrandedPreviewJPEGFilter.inputFormats
= BMP, GIF, JPEG, image/png, TIFF
I have both the JAI Imaging API and JAI Image I/O Tools installed.
When I run the filter-media script I get the following exception - seems
to be choking on the getWidth(null) method call of the BufferedImage
object:

ERROR filtering, skipping bitstream:
We are running Sun Java 1.5.0_18 and a JAI installation from September
2008 on RHEL 5 AS.
Is there a size limit to what the media filter can handle? These images
are generally less than 1MB. Could it possibly be due to a (now)
outdated JAI installation? Or perhaps an incompatibility between current
java version and JAI version?
BTW, I've tested filtering a tif image that worked before (on the 4th
November 2008) and it failed. Anyone have any other ideas or has anyone
come across this problem with tiffs before?
Thanks a lot.
