settings increase transparency.
Shape
Choose an option—First Edge Only, Leading Edges, or All Edges—to demarcate the object’s original shape.
Angle
Rotates the frame of reference for the feathering effect such that, as long as you don’t enter a multiple of 90 degrees, the feathering edges are
skewed rather than parallel to the object.
Gradient Feather
Use the Gradient Feather effect to soften the areas of an object by fading them to transparent.
Gradient Stops
Create one gradient stop for each gradation in transparency that you want for your object.
To create a gradient stop, click below the Gradient Slider (drag a gradient stop away from the slider to remove a stop).
To adjust the position of a stop, drag it left or right, or select it and then drag the Location slider.
To adjust the mid-point between two opacity stops, drag a diamond above the Gradient Slider. Where the diamond is located determines
how abrupt or gradual the transition between stops is.
Reverse Gradient
Click to reverse the direction of the gradations. This box is located to the right of the Gradient Slider.
Opacity
Specifies the transparency between gradient points. Select a point and drag the Opacity slider.
Location
Adjusts the position of a gradient stop. Select a gradient stop before dragging the slider or entering a measurement.
Type
Linear shades from the starting gradient point to the ending gradient point in a straight line; Radial shades from the starting point to the ending
point in a circular pattern.
Angle
For linear gradients, establishes the angle of the gradation lines. At 90 degrees, for example, the lines run horizontally; at 180 degrees, the lines
run vertically.
Use Global Light
You can apply a uniform lighting angle to transparency effects in which shading is a factor: Drop Shadow, Inner Shadow, and Bevel and Emboss.
When you choose Use Global Light with these effects, lighting is determined by the global setting in the Global Light dialog box.
1. Do any of the following to open the Global Light dialog box:
Choose Global Light from the Effects panel menu.
Choose Object > Effects > Global Light.
2. Enter a value or drag the angle radius to set the Angle and Altitude, and click OK.
Set the opacity of an object
You can apply transparency to a single object or selected objects (including graphics and text frames), but not to individual text characters or
