104 Manipulating Images

The straight line segments are

actually bendable curves. When

you alter the contours of the

mesh and distort the initial

rectangular grid, the underlying

image deforms accordingly. To

change the mesh, you simply

move nodes, node attractor

handles, or connecting lines; add

or subtract nodes as needed;

and/or edit nodes to change the

curvature of adjoining lines.

To select a mesh node:

• Click it. (Shift-click or drag a marquee to select multiple nodes.)

One or more attractor handles appear on the selected node(s) and on any

adjacent nodes. The number of handles per node will vary depending on the

number of adjacent nodes.

To warp the mesh:

• Drag a mesh node to move it.

• Drag a line segment to reshape it.

• Drag a node's attractor handles.

To add a new node:

• Double-click on a line segment.

• Click on a line segment then select the Add Node button on the

displayed Context toolbar.

The new node appears, along with extra nodes where the new connecting lines

intersect existing lines. Adding a new node further subdivides the mesh.
