which libs for clipping path recognition

Hello all,
I have one installation where "identify -verbose with-clip.jpg" doesn't show any
clipping path whereas another installation shows such a path on the same test image.
The working installation is from MacPorts and uses libexpat and has no librsvg.
The failing installation is using libxml2.
Which libraries are essential to recognize the clipping path?
Thanks, Axel.

(edit)
Perhaps this is not a library issue.
I debugged further and found that in "property.c"
Code: Select all
profile=GetImageProfile(image,"8bim");
doesn't return any profile.
Does anybody have an idea why this particular "8bim" profile doesn't seem to be extractable?
After building "make check" doesn't report any error.
How could I continue debugging?
Regards, Axel

After reading a few other threads in this forum which mention issues with 'iptc' and '8bim'
profiles I retried with an older versions, using the same build script as before.
6.6.3-10 works fine
6.6.6-3 doesn't work
There is no need to have librsvg or xml support.
I suggest the test routines are expanded to reveal this problem earlier.
Regards, Axel.

Can you post a URL to with-clip.jpg? We'll need to reproduce the problem and we'll follow up with a patch in the next few days. Thanks.

Of course grep will not show any lines between the start and end SVG lines. Thye don't contain the text 'svg'.
Try this..
Code: Select all
ImageMagick-6.6.6-3/bin/identify -verbose with-clip.jpg | sed -n '/<svg/,$p /<\/svg/q'

I'm using "identify -verbose" just for demonstration. The problem shows up with a different test easily:
Code: Select all
> ImageMagick-6.6.6-3/bin/identify -verbose with-clip.jpg | grep -i clip
Image: /Users/ar/work/censhare-projects/rewe/with-clip.jpg
> ImageMagick-6.6.3-10/bin/identify -verbose with-clip.jpg | grep -i clip
Image: /Users/ar/work/censhare-projects/rewe/with-clip.jpg
Clipping path:
Your command returns with an "sed" error message
Code: Select all
> ImageMagick-6.6.3-10/bin/identify -verbose with-clip.jpg | sed -n '/<svg/,$p /<\/svg/q'
sed: 1: "/<svg/,$p /<\/svg/q": extra characters at the end of p command
It would be nice if there were some explicit command to extract the clipping path from any image as SVG.
Regards, Axel.

applogies put a ';' after the 'p'
Code: Select all
... | sed -n '/<svg/,$p; /<\/svg/q'
