I’m working with multiple annotations in the same scene, all of them are AnnotationRuler and I want them all to have same properties. But the only way I’ve found to edit the properties is by clicking on the icon below (in the image) and changing the annotation properties one by one.
Annotations are being replaced by the much more powerful Markups module (in Slicer-4.11). Markups allows you to set display properties (color and visibility) of all markups in a folder at once.
Go to Markups or Data module, create a folder, drag-and-drop markups (lines, angles, fiducial lists, planes, curves, etc.) into that folder, and right-click on the folder’s eye icon to enable “Apply color to all children” to apply folder’s color and visibility options to all markups in that folder.
