64 Manipulating Images<br />
To select a mesh node:<br />
• Click it. (Shift-click or drag a marquee to select multiple nodes.)<br />
One or more attractor handles appear on the selected node(s) and on any adjacent<br />
nodes. The number of handles per node will vary depending on the number of<br />
adjacent nodes.<br />
To warp the mesh:<br />
• Drag a mesh node to move it.<br />
OR<br />
• Drag a line segment to reshape it.<br />
OR<br />
• Drag a node's attractor handles.<br />
Unless you're working in Setup mode, the image responds immediately as the<br />
mesh is warped. The bendability of line segments depends on the type of nodes at<br />
either end. (Both Setup mode and node types are detailed below.)<br />
The Deform Mesh option makes it easy to move, scale, skew, or rotate a portion of<br />
the mesh about a fixed point. It works just like the standard Deform tool<br />
(described above) on multiple nodes.<br />
To deform the mesh systematically:<br />
1. Shift-click or drag a marquee to select multiple nodes.<br />
2. Click the Deform Mesh button on the Mesh Warp Tool's Context<br />
toolbar. A selection rectangle appears around the designated nodes (you may<br />
need to zoom out to see this), with a fixed point in the centre and handles at its<br />
corners, sides, and centre.<br />
3. Click to use the Deform Mesh Tool to move, scale, or rotate a portion of the<br />
region (as defined by nodes) about a fixed point.<br />
• To deform the mesh region, drag from any corner or midpoint handle.<br />
• To rotate the mesh region, drag from just outside any corner handle.
