This idea is to have an option in the Image Indicator to change to Image Display.

Currently to get Image Display Developer needs to right click on the Front panel of Image Indicator -- Replace---Select Vision and the needs to select the kind of diplay needed.

If by default the right click option provides Display also as an option, then its easy to navigate in single selection.

Problem:

I need to acquire images from a camera and rotate them 90-degrees counter-clockwise on a cRIO-9034 target. Rotating the image on the camera sensor is not supported by the camera.

Current situation:

It is currently possible to rotate an image using “IMAQ Rotate.vi”. This VI has a floating point input angle which can be set to 90 degrees. It is however a bit slow (around 80 ms on a cRIO-9034 for a 3840x1200 image). It should be possible to implement a faster way of rotating an image when the angle is in increments of 90 degrees.

My suggestion:

Create a new IMAQ vi for rotating images in increments of 90 degrees. The VI could be similar to "IMAQ Symmetry.vi" which can be used to flip images horizontally and vertically.

When Vision Assistant steps are converted to LabVIEW VI, the overlay of result (i.e. edge detect, particle counts) is lost.

Adding overlay function on VI requires not only LabVIEW skills, but Vision knowledge due to image memory handling.

So it'd be nice to have an option to keep the overlay functionality on Vision Assistant even when converting to LabVIEW VI to have a smooth transition.

I have run into this problem with the Vision run time, Vision Acquisition run time since I began using Labview. The problem here is that every time I upgrade my development software for example Vision Development Module 2016 to 2017 then update my customers they need to actively re-license both the VD run time and VA run times. This seems to make no sense since both run times were already activated in the previous version. This is a real issue when you are updating software on customers machines that have no internet access. The Vision Development run times need to automatically transfer from version to version since the Vision run time keys are good indefinitely for updates. This would prevent customers from having to re-license yearly like they do now which in my opinion does not make sense. At the very least there could be a way to add a 20 character code problematically when updating versions so users don't have to work their way through NI's license manager. 

Similar to Draw Line/Draw Multiple Lines function available for Picture, it would be good to have line styles(as mentioned in the attached image) for IMAQ Overlay Line, IMAQ Overlay Multiple Lines 2.

This is probably not a simple thing for NI to implement but I always thought it would make sense to make the IMAQ image a native data type. When I first started using LabVIEW, it took me a while to get used to the image data type and understand that it is just a pointer to a named image in memory and the pointer is passed between image operators. I am used to it now but it still seems clunky to me. Why can't an image constant or control implicitly create an image and they can be implicitly destroyed at the end of a program. Branching a wire would create two copies of an image that could be operated on independently. At the moment my imaging code always looks quite messy because I often need to create temporary image buffers for intermediate operations.

I think this would make the imaging tools a more wholistic addition to labVIEW and make it feel less like something that was adapted from another language. Sure there would be some impact on performance, but isn't that why we use LabVIEW? Simpler programming at a higher level.
