hide show arrows (Decorations)

[Barionics]

I would like to be able to create on-screen instructions with Arrows pointing to details in a photograph. I was hoping to use the arrows from the decorations pallet, but I am dissapointed to see that they do not exist as programmatic objects, and therefore cannot be controlled using property nodes.    Might I suggest making them into indicators, of a sort, so that they can be controlled by the programmer?

You can.  You'll need to know the order they were laid down, or you'll need to set tags so you can find a particular decoration later, but it's possible.

This is achievable with programmatic access to the decorations through VI Server, as described by jcarmody here: http://forums.ni.com/t5/LabVIEW-Idea-Exchange/hide-show-arrows-Decorations/idc-p/3188663#M32094
