Re: GPU vs CPU on command line benchmark

i was guessing if the underlying lying library is built with OpenCL, no matter if we access through API or command line, i should be able to access GPU with correct env variable.

Re: Caught exception clCreateContext failed while running multiple executions on GPU

I have not tried ImageMagick 7 as the version of imagemagick we have in production is ImageMagick 6. Was there any patch in ImageMagick 7?

Re: get anti-color image when convert to format webp

Hi,

Was this patch applied? I have imagemagick version 6.8.6-6 configured with webp version 0.4.2 and we are seeing the anti-color kind of thing. Here is an example : http://i1.ebayimg.com/images/g/szsAAMXQ ... s-l500.jpg
