Which version of the PNG library is being used in 6.6.1?

I used libpng 1.4.4 in all tests. It is most probably caused by the extensive refactoring of png.c
since 6.6.2(?).

Regards, Axel.

Can you try with an older ImageMagick version?

I found a dramatic performance drop with PNG when going from 6.6.1 to 6.6.6,
see viewtopic.php?f=2&t=17799

time ImageMagick-6.6.7/bin/convert logo: -resize 1000% png32:/tmp/logo.png needs more than 3 minutes time ImageMagick-6.6.1-10/bin/convert logo: -resize 1000% png32:/tmp/logo.png runs in less than 10 seconds (same results for "png24" or "png") both IM versions are linked against ...

I used 6.6.7 from svn.
It still takes ages to create a large PNG with my benchmark.

Regards, Axel.

I hope this is a typo in your command

No. I didn't care about the actual file or the actual operation.
My point is that generating large PNGs is awfully slow compared to other image formats.

Using png24 or png32 doesn't help. It is still awfully slow: > ImageMagick-6.6.6-10/bin/convert logo: -resize 1000% -bench 5 tif:/tmp/logo.png Performance: 5i 0.427716ips 16.320u 0.19483333428867430359:11.690 > ImageMagick-6.6.6-10/bin/convert logo: -resize 1000% -bench 5 png24:/tmp/logo.png Perform...

Issue is resolved with 6.6.6-5

Thanks, Axel.

Thank you for your kind correction!

I'm using "identify -verbose" just for demonstration. The problem shows up with a different test easily: > 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-cli...

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 expa...

(edit) Perhaps this is not a library issue. I debugged further and found that in "property.c" 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 &...

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...
