Setting thread limit = 1 programmatically in Magick++

Post by vigri » 2015-07-15T12:13:34-07:00

Hello,

when I want to "disable" OpenMP while using the convert command I simply use

Code: Select all

convert -limit thread 1 in.png out.jpg
Now I've a C++ program where I'm using the Magick++ API.

My question: Is there a way to limit the maximum thread amount programmatically?

I know about setting MAGICK_THREAD_LIMIT=1 in /etc/Environment - but I would like to set the limit in my code.

Best regards.

If you have a new version of ImageMagick you can do this with the ResourceLimits class.
.NET + ImageMagick = Magick.NET https://github.com/dlemstra/Magick.NET, @MagickNET, Donate
