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.....

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).
