Hi Kate,

I have developed an intensity graph widget for BOY at SNS, which has the capability to display 2D image based on its colormap. I'm planning to add the functions you asked: Cropping, Rubberband zoom, cursor position and value tip, profiling.

Thanks,
Xihui

Subject: edm : TwoDProfileMonitorClass : cropping/resizing image

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
