Resource Editor: Media Annotation (MVP)

[tomcrane]

Also known as a Painting Annotation.

This uses another resource editor component - #94 It wraps it in additional editing, because the media resource is just the body; this editing UI also allows you to set the target.

For MVP this is JUST IMAGES.

The body of the annotation is edited with #94. The target is either the whole canvas, or a part of the canvas. If the canvas editing surface (#98) is visible, changing target values in the form elements moves/resizes the box on the canvas. If the user drags or resizes the box on the canvas, the target properties change.

If you created a Canvas with the New Canvas dialog, #52, then came back to look at that image in the UI, you'd see it in this component.

Fields

Note that type Annotation and motivation painting are fixed and not editable; these annos are, by definition, painting annos.

property	editable here	has further editor
label	#67	no
summary	#67	no
behavior	#109	no
body	yes - inline widget?	#94
target	MVP: x,y,w,h inline	no

The target for MVP is something like:

[ ] whole canvas x: y: width: height:

If "whole canvas" is checked, the xywh are blanked and disabled. These update by themselves if visible and the user drags the annotation on the canvas.

We'll need to accommodate time-based targets later but not MVP.

Question: is this widget available independently? Or do we always wrap it in a Media Annotation Page editor?

[tomcrane]

Here's the "mini" mode:

The body launches #94 but the Target just shows #115 inline.

For painting annotations we condense all the available painting annos in all the pages under canvas.items into a single anno page, and hide the fact that this page is present in the UI.
