The Transparency Tool allows you to apply and edit transparency gradients to vector and text objects.
Gradient transparencies are represented by a path that shifts from solid to grayscale coloring, connected by grayscale stops. The grayscale value of the stop represents the opacity/transparency value.
Black represents fully opaque (100% opacity/0% transparency).
White represents fully transparent (0% opacity/100% transparency).
The following settings can be adjusted from the context toolbar:
Type—converts the object's transparency type to None, Linear, Elliptical, Radial, or Conical.
Select, pick, and modify the object's gradient transparency—click the swatch to display a pop-up panel. See the Gradient editing topic for more information on the settings available.
Rotate gradient—rotates the applied gradient by 90°.
Reverse gradient—the end stops swap places. (All intermediate stops are also repositioned accordingly.)
Maintain fill aspect ratio—if this option is off (default), the end stops can be resized separately which changes aspect ratio. When selected, the end stops are locked to keep the aspect ratio (i.e. changing one will automatically update the other). This setting affects only Elliptical fills.
