Hello,
can anyone tell me how to draw a rotated oval overlay over an image, without having to rotate the image twice (as in https://forums.ni.com/t5/Machine-Vision/How-do-I-draw-an-ellipse-in-IMAQ/td-p/1666796 )? Rectangles are no problem, but I have not found a way to draw a rotated oval. Using Labview 2018SP1 with Vision.
Thank you.

This is a problem for me too. Frustrating that setting the angle on an oval is not a thing.

OK, I brute Forced a solution. Here is a snippet. The output of this VI feeds into "IMAQ overlay points". If you are using Imaq particle analysis to generate the minor / major axis, you will probably want to divide both by half. Let me know what you think.
