Details

Using JPEG as compression inside a TIFF container is broken. As far as I can tell this was introduced with libjpeg-8.

I guess this is most probably an upstream bug but I'm still reporting it here fist because:

a) I'd like to know if other users are affected, too. I only know of few other persons who have seen this but the majority remains silent.

b) I don't know if this is a bug in libtiff, libjpeg or in any of the programs using those libraries.

c) I'm on i686 but I don't know if this applies to x86_64, too.

Package versions:

libtiff 3.9.2-2
libjpeg 8-2
imagemagick 6.5.9.5-1
xsane 0.997-2
sane 1.0.20-5
gimp 2.6.8-3

Steps to reproduce:

There's various ways to reproduce this. Most simple one:

$ scrot bla.jpg
$ convert bla.jpg bla.tiff

Backtrace from xsane (scanning and saving the image as TIFF with JPEG compression -- which is the default if you choose TIFF) is attached.

You could also try to save an image as TIFF with JPEG compression in GIMP. An old test program from the libtiff bugtracker also fails when it comes to JPEG compression:

FTR: Yes, I wrote the post on imagemagick.org forums. Now, I know the problem isn't with imagemagick but with libjpeg.

I have sent an email describing this issue to the author of libjpeg.

Alright, thank you! :)

The bug is known and the fix is on the way with v8a. The author expects the release to appear on 28-Feb.
