Drawing Permanent Rectangular Area on a Picture

[Dushyant]

The main code is  “Rectangle_Delete_N”.

This code takes an entire image and based on our mouse drag, it can choose and display the area of interest. However, the red-dotted boundary that appears are temporary  and I could not figure out a way to make it permanently appear on the “picture” based on two options that I want to choose:

Temporary Boundary/Permanent Boundary

 Please let me know how it can done?

Regards,

DK

Easiest: Put the image terminal inside the TRUE case which is inside the "picture:mouse move" event, right after the "draw rect" icon. Now it won't update in the other events. Try it!

(Also your subVI "proper img display" has about 90% too much code (and currently does not do anything useful). What is it supposed to do? The subVI "DIsplay coor..." does not need any sequence structure.) 😉

Yes, I tried. It worked, but then I cant use the zooming and image stretch features etc.

Never mind, the code works now completely.

Thanks.
