Do you use ImageJ for real-time image display instead of edm : 
TwoDProfileMonitorClass ?
What I need is to use the format 7 (scalable image) of any IIDC cameras 
and crop
out a ROI for DAQ during the "real-time display" of the image.  so far, 
I only
used ImageJ for offline data display (e.g. reading image data from a 
FITS file
instead of DAQ from a camera).

Kate
