Setting node opacity Directional Rectangular
When you edit rectangular or elliptical vector mask styles, add nodes to the horizontal vector that
joins the inner box (which represents the area of 100% opacity) to the object’s bounding box. When
you edit radial mask styles, you can add nodes to the circle, which represents the 360° sweep of the
mask.
Removing a vector mask
Removing a vector mask from an object removes the transparency effect produced by the mask.
1. Select the masked object.
2. Choose Object | SpriteLayers | Detach Mask. Canvas removes the vector mask from the
selected object.
When you detach a vector mask, the former mask appears in the document as a separate vector
object filled with a grayscale gradient.
Vector masks in paint edit mode
If a paint object has a vector mask, Canvas temporarily represents the vector mask as a channel mask
if you edit the paint object.
In paint edit mode, a temporary channel mask that represents the object’s vector mask appears in
the Channel Mask slot in the Channels palette. The temporary mask lets you see the effect of the
vector mask as you edit the paint object.
If you click in the Channel Mask slot to try to select the temporary channel mask for editing, Canvas
asks if you want to convert the vector mask to a channel mask.
