After the shapes are connected, the source shape appears with a light blue path, and
the target shape appears with a dark blue path, indicating that the connection has
been made. Purple connection lines appear between the source and target shapes to
show which parts of each shape are connected.
In the Parameters tab of the corresponding Warper or Morpher node, an additional
connection parameter appears for the connection you established. By default, each
new connection parameter that’s created is named “connection1Name,” with the
middle number incremented as each new connection is created. These names can be
changed to more easily identify each connection for individual manipulation later on.
To disconnect a source shape from a target shape:
m In the Parameters tab of the corresponding Warper or Morpher node, click the Delete
button of the connection parameter you want to break.
After disconnecting a source/target shape pair, both shapes become unassigned, and
turn yellow by default.
For more information about the parameters of the Warper node, see “ Parameters in the
Warper Node ” on page 846. For more information about the parameters of the Morpher
node, see “ Additional Controls and Parameters in the Morpher Node ” on page 855.
Modifying Connection Lines
Once you’ve connected a pair of source/target shapes, connection lines appear to show
the deformation path that pixels in the source shape will follow to conform to the
target shape. These connection lines can be moved to change the path and alter the
look of the warp or morph effect. You can also add more connection lines to increase
the amount of control you have over the warp or morph effect.
To move the start or end point of a connection line independently:
1 Click the Edit Connections button.
2 Drag a connection point to another location on the shape. The connection point’s
movement is restricted to the contour of the shape.
To move the entire connection line at once:
1 Click the Edit Connections button.
2 Drag a bounding box or Shift-click each point to select both the start and end points of
the connection line you want to move.
