Sorry for having this message to appear the 2nd time.  Somehow the clock on
my laptop was slewed over time that the 1st message was logged ahead of your
original message.   Same message below just in case.....

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.

Regards,
Kate

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.

I am using the edm/TwoDProfileMonitorClass for a real-time
image display. Has anyone implemented a point-and-click resizing
tool via the mouse for that class so that one can interactively crop
out a section of the real-time image ?

A simpler implementation would be to have an active cursor
being moved around the real-time image and have a text
message to display the current (x,y) pixel location of the cursor
for users to use it as a reference or an activation point
to define the location of the cropping. Is this already
implemented in the edm video widget ?  Please advise.

Regards,
Kate
