You can manipulate vertices and tangents during and after mask creation. Edit vertices and tangents gesturally when the edit
mode is set to Move or Break. Alternatively, edit them using the Vertices tab.
Vertices selected as a group can be transformed around a localized pivot. The angle and length of tangent handles can also
be manipulated as a group.
Selecting Vertices and Tangents
You can select vertices and tangent handles when Move is selected in the Edit Mode box.
- To select an individual vertex or tangent handle, click the vertex or tangent handle.
- To select multiple vertices, Ctrl-drag a selection box over a series of vertices.
- To select multiple vertices using the pen, press the pen button and drag a selection box over a series of vertices.
- To add more vertices to an existing selection, press Shift+Ctrl and drag a selection box over the additional vertices.
- To deselect all vertices, click anywhere outside the mask.
Moving Vertices and Tangents
You can move vertices and tangents using the Move option of the Edit Mode box:
- To move a vertex or tangent in any direction, select Move. Click the vertex or tangent and drag.
- To move selected vertices in any direction, select Move. Click one of the selected vertices and drag.
- To ensure better continuity on a garbage mask, automatically adjust tangents as you move vertices or scale the mask. Enable
Auto Adjust and drag a vertex. To toggle temporarily enable or disable Auto Adjust, press and hold G and then drag a vertex. Auto Tangents must be enabled to use the Auto Adjust feature.
- To keep tangent handles an equal length, Ctrl+Alt-drag one vertex handle to automatically change the length of the other tangent handle at the same time.
You can use the Vertices tab to move vertex and tangent positions.
The Selection fields display the current position of the vertex. If multiple vertices are selected, the position displayed
is of the vertex that is closest to the initial vertex created in the mask.
Depending on the Transformation and Pivot Type options, you can move sets of selected vertices by editing the Translate, Scale,
Shear and Rotation fields. You can also move tangent handles independently.
