How to get multiple ROI

[JoshMonkey]

I've read from previous posts that to get multiple ROI, one way is to generate array of ROI. After getting the array of ROI, what do I do with it?

My aim is to extract rect (or any shape) regions from the original image to a dest image. Is there any example on how I can achieve this? Thanks

Hello.

I have attached a little example mockup of taking an ROI and using it to extract a piece of an image to a second image. Basically, (using LV 7.0 or later), you can get the ROI property from the image display, then use the ROI to Rectangle function to convert it to a bounding rectangle, then you feed that information into an IMAQ Extract VI, which takes a portion of an image and copies it into a destination image.

This should get you on your way.
