When I convert jpg file with quality 70 use the library, the quality of the jpg file is 34. As while, when I set quality to 88, the jpg file隆炉s real quality change to 70. But, I use the gm command to do the same things, the qualities are all right.

This issue seems likely to be due to "ImageMagick bindings for Go" so 
I suggest that you persue an issue there first.

It sounds like some other parameter besides 'quality' is being passed 
as the quality.  This could be a binary interfacing issue.

Did you compile this binding yourself or did you find it precompiled?
