Dynamic gradients

You can control transparency gradients in the same manner as color gradients. Both

types of gradient can be used together. With a transparency gradient, the direction

and degree of an object’s fill color changes from opaque to transparent (in a regular

gradient, the fill changes from one color to another, but the degree of transparency

remains the same).

If you have assigned transparency to an object with a color fill, you can control the

transparency by clicking on the Transparency icon . To define a transparent

gradient, select an object, choose a transparency fill from the Line and Filling

toolbar, The transparency icon is now active. When you click on this icon, a dashed

line connecting two squares appears on the object. Move the two squares to modify

the gradient. You can define the direction of the gradient (vertical, horizontal, or at

any angle) and the spot at which the transparency begins.

A regular color gradient can be defined in the same manner. Select an object, choose

a gradient fill from the Line and Filling toolbar. The Gradient icon is now

active. When you click on the gradient icon, a dashed line connecting two squares

appears on the object, just as it does for a transparency gradient.

In both cases, click outside the object to set the gradient.

Note

If the transparency and gradient icons are not visible, you can display

them using View > Toolbars > Mode.

Moving the squares will have different effects, depending on the type of

gradient. For example, for a linear gradient, the start and end squares of

the gradient will always be situated to either side of the center point of

the object.

The three examples in Figure 104 demonstrate how the type and degree of

transparency can be controlled.
