The Transparency Tool allows you to apply and edit transparency gradients to vector and text objects.
Gradient transparencies are represented by a path 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:
Context—for selected text frames only, the transparency can be applied to the frame Text or the Frame itself.
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 and Bitmap fills.
