150 Painting and Drawing
Each tool's supporting context toolbar lets you create the line on
a shape layer, as a path or directly as a filled bitmap. Additionally, combination
buttons let you add the line to its own layer (or path), and can also be used to
control how the new line interacts with existing shapes on the layer.
Besides being useful with QuickShapes, the Node Edit and Shape Edit tools
really come into their own when editing lines.
To edit a line:
1. Click its layer name to select the layer.
2. To move, resize, scale, skew, or rotate the line, choose the Shape Edit
Tool. This deform tool works by manipulation of the bounding box around
the line—drag on a corner or edge. (For details on its use, see Deforming on
p. 108.)
3. To reshape the line, choose the Node Edit Tool. The line consists of
line segments and nodes (points where the line segments meet). You can
drag one or more individual nodes, or click and drag directly on a line
segment.
When you select a node, control handles for the adjacent line segments appear;
each segment in the line has a control handle at either end. The selected node is
drawn with a red center, with the control handle(s) attached to the nodes by blue
lines.
Any node can be one of several node types: sharp, smooth, or symmetric.
Depending on node type, the node's control handles behave a bit differently, as
you can tell with a bit of experimentation. Essentially, the node type determines
the slope and curvature of each adjoining segment, and can be chosen from the
Context toolbar, i.e.
