Assertion in jpc_dec_tiledecode

[j2043]

Hey folks,

I get:

Code: Select all

identify: jpc_dec.c:1072: jpc_dec_tiledecode: Assertion `dec->numcomps == 3' failed.

When I try and process the following image:

I'm processing the image with rmagick. The assertion causes ruby to exit violently.

Debian etch running image magick 6.5.8-2 with jasper 1.900.1

Curious. We have the same set up under Fedora your image displays without complaint. We're using Jasper 1.900.1-14 and ImageMagick 6.5.8-2.

Ok, from the Fedora RPM information I see this:

* Sun Jan 25 2009 Rex Dieter <rdieter@fedoraproject.org> 1.900.1-9
- patch for "jpc_dec_tiledecode: Assertion `dec->numcomps == 3' failed)
(#481284, #481291)


So it looks like Red Hat applies some patches to Jasper.

What is your recommendation for compiling jasper from source? Should I track down patches and apply them my self?

Do you happen to know if http://www.ece.uvic.ca/~mdadams/jasper/ is the right place to get it?

That is where we pick it up.
