convert outputs the following message every time when resizing images.
Code: Select all
convert: clCreateBuffer failed. . @ warning/accelerate.c/ComputeResizeImage/2823.
works fine, but when resizing like
convert -resize 100x test.jpg test-100.jpg the message shown above appears. The action itself (e.g. resizing) works properly: The image gets resized. convert just returns said error message in addition.
Additional info
Steps to reproduce
- install imagemagick 6.8.7-7
- perform convert -geometry 100x test.jpg test-100.jpg

I downloaded ImageMagick-6.8.7-9.tar.bz2, configured and built the software, but I am still getting the error:
lt-convert: clCreateBuffer failed. . @ warning/accelerate.c/ComputeResizeImage/2816.

It means your GPU does not have enough memory so it reverts to the host CPU. You should get correct results despite the warning. We're looking toward making the warning silent if the GPU does not have enough memory.

Is the warning new to version 6.8.7?
We had previously build 6.8.6-9 and see no warning - now I wonder if the GPU is actually being used.

Expanded GPU support is a recent contribution, just a few weeks old. It works well but does require a few tweaks.

We noticed another bug in detecting the device that will be used. We will have a patch in ImageMagick 6.8.7-9 Beta available by sometime tomorrow.
