156310 - YCCK-encoded jpeg images will not render

Status: VERIFIED DUPLICATE of bug 44781

(Core :: Graphics: ImageLib, defect)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020605
BuildID:    2002060511

The url says it all, the picture does not render and the following text is
displayed:

The image “http://patrick.spacesurfer.com/mozbug.jpg” cannot be displayed,
because it contains errors.

This jpeg renders fine in ImageMagick and the gimp, but appears to render with
the wrong colours in konqueror. Could be something to do with the CMYK colour
encoding.

Reproducible: Always

This bug was erroneously marked as a duplicate of 121084. My mozilla build is
not affected by 121084 and this bug is not cache related. If I save the jpeg as
a gif it renders fine. This bug appears to be a problem decoding certain jpegs.

Why do you think that this is not cache releated ?

Does it work if you do this :
Edit\preferences\advanced\cache\comapare...\[x] Every time I view the page
and clear the disk cache..

[Patrick Xia]

not a dupe; not cache related. first visit = incorrect rendering.

Comment 5

[Matthias Versen [:Matti]]

yes, i see it now.

IE5.5 shows a broken Image and NS4.7x can't render it correct.

invalid ?

It loads fine in Paint Shop Pro.

Comment 7

[patrick]

The image is valid, renders fine in ImageMagick and gimp, however it comes up
with the wrong colours in Konqueror. In think the image is CMYK encoded instead
of themore popular RGD

It's actually in the YCCK format which is some Adobe weirdness. Not
surprising since the comments say Photoshop wrote it. The image is
correct but I don't think mozilla should waste it's time tring to decode
obscurities like this. Since Photoshop wrote it Photoshow can just as
easily re-write it in a common format.

I think the only mozilla bug here is that mozilla doesn't say why it's 
unhappy with the image.

Comment 9

[Aaron Kaluszka]

I disagree.
Does Mozilla support CMYK images?  If so, there should be a simple conversion
from YCCK to CMYK (as there is YCC to RGB).  If we don't support CMYK, YCC, or
YCCK, I'll change the summary again to cover all three.
