To knock out (or visually hide) the source object and display only the gradient glow on the knockout image, select Knockout.
Specify a gradient color for the glow. A gradient contains two or more colors that fade or blend into one another. The color you select for
the beginning of the gradient is referred to as the alpha color.
To change a color in the gradient, select one of the color pointers below the gradient definition bar and click the color space that appears
directly below the gradient bar to display the Color Picker. Sliding these pointers adjusts the level and position of that color in the
gradient.
To add a pointer to the gradient, click on or below the gradient definition bar. To create a gradient with up to 15 color transitions, add up
to 15 color pointers. To reposition a pointer on the gradient, drag the pointer along the gradient definition bar. To remove a pointer, drag
it down and off the gradient definition bar.
Select the quality level for the gradient glow. High is approximate to that of a Gaussian blur. Low maximizes playback performance.
Apply a gradient bevel
Applying a gradient bevel produces a raised look that makes an object appear to be raised above the background, with a gradient color across the
surface of the bevel. The gradient bevel requires one color in the middle of the gradient with an alpha value of 0.
1. Select an object to apply a gradient bevel to.
2. In the Filters section of the Property inspector, click the button, and select Gradient Bevel.
3. Edit the filter settings on the Filter tab:
Select the type of bevel to apply to the object from the Type pop-up menu.
To set the width and height of the bevel, set the Blur X and Y values.
To affect the smoothness of the bevel without affecting its width, enter a value for Strength.
To set the angle of the light source, enter a value for Angle.
To knock out (or visually hide) the source object and display only the gradient bevel on the knockout image, select Knockout.
Specify a gradient color for the bevel. A gradient contains two or more colors that fade or blend into one another. The middle pointer
controls the alpha color of the gradient. You can change the color of the alpha pointer, but you cannot reposition this color in the
gradient.
To change a color in the gradient, select one of the color pointers below the gradient definition bar, and click the color space that
appears directly below the gradient bar to display the Color Picker. To adjust the level and position of that color in the gradient, slide
these pointers.
To add a pointer to the gradient, click on or below the gradient definition bar. To create a gradient with up to 15 color transitions, add up
to 15 color pointers. To reposition a pointer on the gradient, drag the pointer along the gradient definition bar. To remove a pointer, drag
it down and off the gradient definition bar.
Apply the Adjust Color filter
The Adjust Color filter allows you to finely control the color attributes of the selected object, including contrast, brightness, saturation, and hue.
1. Select an object to adjust the color for.
2. In the Filters section of the Property inspector, click the button, and select Adjust Color.
