Drawing

Tags:

This is a simple drawing editor that supports drawing in a style similar to that found in MS PowerPoint? and MS Word. Various shaped figures can be placed in the drawing and text annotations joined to them.

A drawing can also have a "map" which makes figures in the drawing sensitive to the mouse cursor. A map is automatically added to an image when a URL is attached to any of the figures.

How you edit a drawing depends on whether the drawing has a map and the setting of the "EDIT_BUTTON" option. A drawing with no map can be edited simply by clicking on the drawing. A drawing with a map can be edited by clicking the edit button or, failing that, on the boundary of the image.

Syntax Rules

• Write the command %DRAWING{name}% anywhere in a topic. You can name the drawing anything you like, allowed characters are A-Z a-z 0-9 _ - . . If you have only one drawing in the topic you can simply write %DRAWING% .

Tools

The tools on the left create or manipulate figures.

	selects, moves or resizes a figure; the shift-key toggles the selection. Dragging the selection tool in the background selects the figures within the dragged rectangle.
	creates a new or edits an existing text figure
	creates a new text figure and attaches it to the clicked figure. Once a text figure is attached it remains connected to the figure.
	creates a rectangle figure
	creates a round rectangle figure
	creates an ellipse figure
	creates a line figure
	creates or adjusts connections between figures. A connection is split into segments by dragging a point on the connection. To join two segments click the end point of a segment
	creates an elbow connection and offers the same features as the ordinary connection tool
	creates a scribble figure; dragging the mouse creates a smooth line while successive clicks yields a polyline figure. A two-button click terminates the figure.
	creates a polygon figure; dragging the mouse creates a smooth border while successive clicks yields a polyline border. A two-button click or the ESCAPE key terminates the figure.
	decorates the clicked figure with a border
	adds a sensitive area to the figure that will redirect to a URL. If an image contains any sensitive areas it can only be selected for edit by clicking on the boundary or (if enabled) the attached Edit button. You can use wikiwords and web.topic wiki link expressions as well as full URLs.
