Graffle
Defined in:

Overview

(The following is much more obvious if you look at a sample document.)

The sheet contains one or more rivulets of Graffle::ShapedGraphic objects connected with Graffle::LineGraphic objects. All together, they’re supposed to represent a user workflow. (The gap between one rivulet and the next typically means that the user has gone away from the app, then returned.)

graphics produces a concatenated array of the rivulets (both the Graffle::ShapedGraphic and Graffle::LineGraphic objects).

Suppose there’s more than one rivulet on the Graffle::Sheet. graphics produces all the elements of the first, followed by all the elements of the second, etc. The first rivulet is the one headed by the highest object on the page. After all of its elements have been placed in the graphics array, the next rivulet is headed by the highest remaining element on the Graffle::Sheet.

Within a single rivulet, location is irrelevant. All that matters is where lines start and end.

Notice that the head of the second rivulet may be higher than some element of the first.

A rivulet may have a single element.
