Class: CrosshairsTool
CrosshairsTool is a tool that provides reference lines between different viewports of a toolGroup. Using crosshairs, you can jump to a specific location in one viewport and the rest of the viewports in the toolGroup will be aligned to that location. Crosshairs have grababble handles that can be used to rotate and translate the reference lines. They can also be used to set the slab thickness of the viewports by modifying the slab thickness handles.

doneEditMemo()
doneEditMemo():
void
This clears and edit memo storage to allow for further history functions to be called. Calls the complete function if present, and pushes the memo to the history memo stack.
This should be called when a tool has finished making a change which should be separated from future/other changes in terms of the history. Usually that means on endCallback (mouse up), but some tools also make changes on the initial creation of an object or have alternate flows and the doneEditMemo has to be called on mouse down or other initiation events to ensure that new changes are correctly recorded.
If the tool has no end callback, then the doneEditMemo is called from the pre mouse down callback. See ZoomTool for an example of this usage.
Returns

createAnnotationMemo()
staticcreateAnnotationMemo(element,annotation,options?):object
Creates an annotation memo storing the current data state on the given annotation object. This will store/recover handles data, text box and contour data, and if the options are set for deletion, will apply that correctly.

that the annotation is shown on.
• annotation: Annotation
to store a memo for the current state.
• options?
whether the annotation is being created (newAnnotation) or
is in the process of being deleted (deleting)
- Note the naming on deleting is to indicate the deletion is in progress, as the createAnnotationMemo needs to be called BEFORE the annotation is actually deleted.
- deleting with a value of false is the same as newAnnotation=true, as it is simply the opposite direction. Use undefined for both newAnnotation and deleting for non-create/delete operations.
