5 To adjust the location of the starting or ending opacity, do one of the following:
Drag the corresponding opacity stop to the left or right.
•
Select the corresponding opacity stop, and enter a value for Location.
•
6 To adjust the location of the midpoint opacity (the point midway between the starting
and ending opacities), do one of the following:
Drag the diamond above the gradient bar to the left or right.
•
Select the diamond and enter a value for Location.
•
7 To delete the opacity stop you are editing, click Delete.
8 To add an intermediate opacity to the mask, click above the gradient bar to define a
new opacity stop. You can then adjust and move this opacity as you would for a starting or
ending opacity. To remove an intermediate opacity, drag its transparency stop up and off
the gradient bar.
9 To create a preset gradient, enter a name in the Name text box and click New. This
creates a new gradient preset with the transparency setting you specified.
Creating noise gradient fills
In addition to creating smooth gradients, the Gradient Editor dialog box lets you define a
new noise gradient. A noise gradient is a gradient that contains randomly distributed
colors within the range of colors that you specify.
Gradient with different Noise values:
A. 10% noise B. 50% noise C. 90% noise
To create a noise gradient:
1 Select the gradient tool
2 Click in the gradient sample in the options bar to display the Gradient Editor dialog box.
3 To base the new gradient on an existing gradient, select a gradient in the Presets
section of the dialog box.
4 Choose Noise from the Gradient Type pop-up menu.
5 To set the roughness for the entire gradient, enter a value in the Roughness text box,
or drag the Roughness pop-up slider.
6 To define the color model, choose a color model from the Color Model list.
7 To adjust the range of colors, drag the sliders. For each color component of the color
model you've selected, you can drag the sliders to define the range of acceptable values.
For example, if you choose the HSB model, you can restrict the gradient to blue-green
hues, high saturation, and medium brightness.
8 Set the options to restrict colors or to add transparency.
