ImageMagick 7 installation error
Trying to install imagemagick and I got an error. ImageMagick Version: 7.0.6-0. /usr/bin/ld: /usr/local/lib/libjbig.a(jbig.o): relocation R_X86_64_32S against `.text' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libjbig.a: error adding symbols: Bad value collect2:...

Re: memory leak
You are seeing overhead associated with setting up the OpenMP parallel environment. We can't control that, its part of the libgomp library, not ImageMagick. Or perhaps libgomp has a destructor we can call, but we are not aware of an destructor API call. You can build ImageMagick without OpenMP enab...

Re: memory leak
Thanks @magick, In my system it shows error, is it because of IM version? It sows weird error. I couldn't able to understood it.

Re: What hardware works best?
@snigbo, you are right. I tested with higher resolution image and IM used 70% to 80% of RAM.
It works fine with smaller images.

Re: What hardware works best?
@snibgo, could you give a recommendation about hardware? As I have a similar configuration except RAM. I've only 512 MB RAM. I'm using wand C API. I have tested just with normal resize operation on image. And when I perform multiple HTTP request continuously, my CPU usage goes to 100% and if I fired...

Performance Improvement
I have been writing few custom image effects using MagickWand C, and later on use that effects. Some effects are slow as they contains so many operations. I have written Clone and Destroy wands on many places so I guess it might affect on speed. There is a memory pool but I think it might be very di...

Re: Help me to find high saturation and brightness colors.
I checked the output. It gives me the perfect output. Could you notice, there is a HDRI in features. So as @snibgo said, I think the HDRI might causes the differences. And I have installed ImageMagick from source for Linux. Version: ImageMagick 7.0.5-9 Q16 x86_64 2017-06-01 http://www.imagemagick.or...

Re: Help me to find high saturation and brightness colors.
Check below code, you will get the sparse colours from it. This is the first part, double sparse_args hold all sparse colours, now you just need to pass sparse_args to second part. Check my previous post for second part. Let me know if you still not get the expected output. MagickWand * wand, * wand...
