ROI Scaling [message #55048] Tue, 31 July 2007 06:13

Hi folks,

I run into a small problem when scaling a IDLgrROI object. I want the
ROI to stretch out so that it's slightly bigger. I'm using the SCALE
function to achieve this:

oRoi->Scale, [1.5,1.5]

The scale function does what it promised; the ROI grows bigger.
Unfortunately the position of the ROI gets messed up and the ROI moves
upwards or even out of screen. Does someone know what causes this? I
can't find more info or parameters in IDL's helpfile ;-)

Regards,
Erik
