For example, a linear vector gradient blends colors along a straight axis. A directional vector mask fades from opaque to transparent along a linear axis. For linear vector gradients and directional vector masks, you can specify the length and angle of the axis. The relationship between vector gradients and vector transparency masks can be seen if you detach a vector transparency mask. With a masked object selected, choose Object > SpriteLayers > Detach Mask. Canvas removes the vector mask and places it in the document as a separate vector object. If you examine this object, you see that it has a vector gradient. The gradient style is similar to the vector mask style. The vector gradient fades from black to white in the same way that the vector mask caused the masked object to fade from transpar- ent to opaque. The relationship between vector masks and vector gradients also works in reverse: You use a vector gradient-filled object as a vector mask; see “Masking with a vector object” on page 20.371. Applying vector masks You can apply a vector mask using the Vector Transparency tools. When an object is selected, you can drag one of these tools near or over the object to apply a transparency effect. The Vector Transparency tools provide the easiest way to create transparency effects such as vignettes (image that appear in ovals and other shapes) as well as linear, radial, or rectangular fades. A vector mask is related to a vector gradient If you detach a vector mask, you get an object with a gradient. The grays in the gradient correspond to transparency levels in a masked object.
