Re: openCL slows down complex command

Update: I compiled with debug on.

Once I compile for "release" the result is that OpenCL does not get used in the above command. Any way to have imagemagick get used to speed it up?

openCL slows down complex command

Hello - I clearly am in over my head. Before I invest in multi core CPU's to address my needs, I want to make sure I there is no way to speed up the following command (for processing images to fax format): convert <filename> -auto-orient -background "#FFFFFF" -resize 1728x2200 -gravity center -exten...

Re: Fax image processing (needs to be fast)

What are your thoughts about true cores vs hyperthreaded cores? Your cpu only has 4 real cores. The hyperthreading I've read on average can speed up threaded applications roughly 10-15%. Is there a way to perform the benchmark with hyperthreading turned off or to account for which logical core being...

Re: Fax image processing (needs to be fast)

The monochrome operation is indeed fantastic. Do you know offhand if this is the kind of operation where throwing more cores at it would result in a faster running time? Is it threaded? Thanks in advance.

Fax image processing (needs to be fast)

Hello! Thank you for the great information. There are some posts on the non-php side of things about processing photos for faxes. However they are in CLI format and also seems to be very resource intensive. As of now I have gone down two paths: quantizeImage(2, Imagick::COLORSPACE_GRAY, 2, TRUE, FAL...
