"Smeared lines" in the pictures?

[dguldstrand]

I've just installed Gallery 3 and uploaded some photos, (with ImageMagick).
Immediately noticed that some images have a smeared "stretch / line" to the right.

How can this be?
(See attached image.)

What version of IM? What platform? What is your IM command?

What version of IM? What platform? What is your IM command?

OS: Debian
ImageMagick version: 6.6.0-4

Command: Not sure.. i´m using Gallery 3

Without further information about your IM commands, all I can suggest is that you upgrade IM. It is over 200 releases behind and may have had a bug. The other suggestion is to try other image formats and see if the result is the same. Also perhaps post your input image(s).

At this point we have no idea what processing you and Gallery are doing! Perhaps you need to contact Gallery

Bellow is the original image.


EDIT: I tried with the same file, but in GIF and PNG-format, and i can't see any smeared lines on thoose images.
So it seems, that theare a some issues with jpeg-images.

It is then likely to be due to your libjpeg. You may need to upgrade that.

I do not have any problem converting your jpg input to another jpg using IM 6.8.3.7 Q16 Mac OSX Snow Leopard.

Type convert -list format and look at the version it shows:


JPEG* JPEG rw- Joint Photographic Experts Group JFIF format (80)
JPG* JPEG rw- Joint Photographic Experts Group JFIF format (80)


This is version 8 and you may have version 6 or 7 or perhaps it is not correctly installed.

Yes, it seems that i have old versions installed.
JPEG* JPEG rw- Joint Photographic Experts Group JFIF format (62)
JPG* JPEG rw- Joint Photographic Experts Group JFIF format (62)

Not sure if there are newer versions for Debian, thoo.

check to see if you have more than one version of libjpg. there could be a conflict.

find /usr | grep "libjpeg"
find /opt | grep "libjpeg"

Yes, it seems that i have both version 6 and 8 installed.
I tried to removed them both, and then i installed libjpeg8, but the old version is still there.

root@jupiter:~# find /usr | grep "libjpeg"
/usr/lib/libjpeg.so.8
/usr/lib/libjpeg.so.8.0.2
/usr/lib/libjpeg.so.62

"convert -list format" says that i´m still using the old version instead of version 8.
How to fix that?

I would think you need to clean out all of the 62 version, be sure you have clean version of 80 that is properly installed and reinstall IM

Well, i have allready tried to uninstall/remove the old version, but it seems it's "bundled" with lots of other applications.
So i can't just remove it, right?

Yes that may be true. Sorry, I am not sure how to recompile IM and tell it which version of libjpeg to use. Check the config options at http://www.imagemagick.org/script/advan ... lation.php
