professor_rumsdiegeige Posted February 18, 2008 Report Share Posted February 18, 2008 Hello forum! I'm using Labview 8.2.1 and the Vision toolbox. I create an image display control on the frontpanel, und I would like to define more than one ROI using this image display control. Is this possible, and if so, how? Thank you in advance.

Is this possible, and if so, how? Draw the first ROI, then hold down the ctrl key while drawing subsequent ROIs. Quote Link to comment
professor_rumsdiegeige Posted February 19, 2008 Author Report Share Posted February 19, 2008 Thank you. And how can I query those ROIs from the code behind? Currently, I use a refernce to the image display control, use the property "ROI", but with that I only get the first one, right? Quote Link to comment

No, not right. You will get a cluster with two members: bounding rect and array of contours of all ROIs. Try it. best regards, Andrey Quote Link to comment
