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. - Bruce
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
