Hi,
In analyzing an image, I would like to display it using iTools and
draw several rectangular ROI's in it.
I would then like to query the IImage for the location and dimension
of the ROIs. Any clues on how to do that?
Thanks,
Mirko

Hey Mirko,
I know that some may consider it funny to talk to myself, but for
future reference here is a somewhat unsatisfactory way of extracting
ROI vertices from an iImage:
oSys = _IDLitSys_GetSystem()
oVertices = oSys -> GetByIdentifier('/DATA MANAGER/VERTICES')
fSuccess = oVertices -> GetData(mVertices)
The problem with this method is that if there are multiple VERTICES
objects in the Data Manager, it retrieves only the first one. I could
not figure out how to get the other ones. But this method will have
to do for now.
bye
Mirko
