Gradient fills, like the top sample are quick and
easy in vector programs. You also have the option to blend objects
as shown in the bottom graphic. Combine two or more shapes to create
dynamic effects with a few mouse clicks.

In the first part of our discussion about gradient fills, Color
Power with Gradient Fills, we looked only at raster programs.
This time, we are focusing on gradient fills in Adobe Illustrator
and Macromedia Freehand. In some ways, gradient fills are very similar
for vector and raster programs, but vectors offer more options to
achieve the gradient look. In most cases, you not only have the familiar
gradient fill for objects, but also the ability to blend two objects
together. We will not be able to look at all the possibilities for
blends, since that subject would fill an entire tutorial and then
some. However, I did want to introduce the concept of using blends
as we talked about gradients, since the effect is similar
The samples at the left show a standard gradient fill in the star,
and a blend from a blue circle to a yellow star in the lower sample.
If you have not used object blends, the possibilities should come
rushing at you. Any object can be blended with any other, or many
others. You can even choose which points on one object should blend
with another for total control.
Before you begin, if you have not already read the first part of
this series, please read the introduction to Color
Power with Gradient Fills.
In part one, we looked at solutions to banding, or lines of color
appearing where smooth transitions should be. Adding noise or applying
a blur filter can help when working in raster programs, but these
effects are not possible with vector graphics. You can rasterize the
object in the vector program, but the effects tools do not equal the
power of a raster program like Photoshop. If you have a problem with
banding, it is often most efficient to create your object in the vector
program and optimize it in a raster program. For many gradient fills
or blends, this will not be necessary, but it is an option when the
vector export controls do not deliver the quality you require for
Web graphics.
With that caution presented, let's see what your vector program can
do for you.
