Editing envelopes

After you've applied an envelope to an object, you can edit the envelope in a variety of ways — you can change its editing mode, apply a new mapping mode, convert envelope segments from lines to curves and vice versa, and edit an envelope's node. You can add, remove, move, or change the shape of envelope nodes.

The editing modes control the shape of the envelope itself. Three of these modes — Straight Line, Single Arc, and Double Arc — let you drag a node or control point horizontally or vertically to change the shape of one side of the envelope. The fourth mode, Unconstrained, lets you drag a node in any direction to make more dramatic changes. In addition, the Unconstrained mode has control points for each node, which let you make precise adjustments to get the exact envelope shape you want.

By applying a new mapping mode, you change how CorelDRAW fits the object to the envelope, not the shape of the envelope itself. There are four mapping modes: Horizontal, Original, Putty, and Vertical. A fifth mode, Text, appears if you're using the envelope to reshape Paragraph text.

As with object segments, envelope segments can be converted from curves to straight lines or from straight lines to curves. By changing the segment's type, you change the way the envelope reacts when it's edited.

When you add nodes to an envelope, you can make minute adjustments to give the envelope a more complex shape. You can simplify the envelope's shape by removing nodes.

The most basic method of editing an envelope is to move its nodes. For example, you can move adjacent nodes an equal distance in the same direction.

You can change a node's type, which changes the way the envelope segments on either side pass through the node. Changing the node type changes the shape of the envelope, which in turn changes the effect the envelope has on the object.
