mask.

Editing values in the Transparency palette
Change values in the Transparency palette to make precise changes to a vector mask. When you
change the mask settings, Canvas updates the mask handles to match the current position values.
To edit a vector mask via the Transparency palette:
1. Select the masked object and click Edit in the Transparency palette.
2. Change the following values to modify the effect of the vector mask.
Transparency Start: The transparency percentage at the edge of the vector effect. If
this value is 100%, the object appears completely transparent beyond this point. When
you first apply a mask in rectangular or elliptical style, this point is represented by the
handle at the edge of the object.
Transparency End: The transparency percentage at the end of the vector effect. If this
value is 0%, for example, the object is not transparent at this point. When you first apply
a mask in the rectangular or elliptical style, this percentage corresponds to the area
enclosed near the center of the object, which is 0% transparent. For radial style, the start
point is the handle on the perimeter of the circle. The end is at an opposite point on the
circle.
Left: The distance of the first handle from the left edge of the object, measured as a
percentage of the object’s width.
Top: The distance of the first handle from the top edge of the object, measured as a
percentage of the object’s height.
Width: The horizontal distance to the second handle from the first handle, measured as
a percentage of the object’s width.
Height: The vertical distance to the mask’s second handle from the first handle,
measured as a percentage of the object’s height.
