The performance improvement to NDPluginTransform is first present in ADCore R2-1.
The performance improvement between R2-0 and R2-1 ranges from a factor of 13 to 85 depending on the transformation, and is documented here.

Hi Mike,
What version of areaDetector are you using? In areaDetector 1-NN this plugin performed rather unimpressively. However in areaDetector 2 (ADCore); Chris Roehrig did an “Extensive re-write” (May 2014) which increased performance e19490e<https://github.com/areaDetector/ADCore/commit/e19490e260bd427ddc981c00ced3a0b9ba8f82e2>.
Cheers,
Ulrik

Subject: NDTransform Image Delay
I am using the NDTransform plugin for AreaDetector, so I am able to rotate images acquired by a camera. This works completely fine, unless the acquire time of the camera is 0.1 or smaller (reading in images at 10Hz or faster).
At these rates, there is a delay applied to the camera, i.e, if the camera sees something different, the image the AreaDetector software returns won’t show the change for around 5 seconds. I assumed that the rotation was just taking a long time to process, but the overlays I apply after the transformation have no delay at all. I have also noticed that when this delay occurs, the ‘DroppedArrays’ PV for the NDTransform plugin increases.
Is there a way to stop this delay from happening?
Thanks,
Mike
