Here are a couple of ideas:

- I've got an ImageJ plugin that displays EPICS waveform images from the areaDetector module.  It is quite flexible for zooming, line profiles, etc.  It uses the native Java implementation of CA.

- If your cameras are supported by areaDetector, then it comes with a very flexible region-of-interest plugin that lets you select regions of the image, reverse axes, bin, etc.  The ImageJ viewer responds immediately to such changes in the selected area of the image.

Subject: Re: edm : TwoDProfileMonitorClass : cropping/resizing image

We've had similar requests here at SLAC.   We use TwoDProfileMonitorClass
with EDM for our cameras, and are looking for an easier way to select
the region of interest.   We looked briefly into doing a Python/QT camera
viewer with this feature, but haven't had time to get serious about it.

If anyone has a solution for this, we'd be interested in hearing about it.
