Drawing a Straight Line
To draw a straight line:
1 Click the location in the image where you want the line to begin.
2 Press Shift and click the location in the image where you want the line
to end.
The line is drawn between the two points.
Painting the Alpha
You can retouch mattes with the paint tool.
A new internal layer has an empty, black layer matte. An external layer's alpha
contains the matte information of the incoming image.
Painting on the alpha of an internal layer is accomplished in one of two ways:
implicitly or explicitly. Implicit alpha strokes are added when you paint on
the layer front. For every stroke added to the layer front, a corresponding
stroke is added to the layer alpha. Explicit alpha strokes are added when
painting directly on the layer alpha.
Painting on the alpha of an external layer can only be accomplished explicitly.
When you add strokes to the layer front, corresponding strokes are not added
to the alpha.Strokes added explicitly to the layer alpha will be visible on the
layer front (nor in its proxy) in composition view when you commit the
stroke(s).
Pen to be removed from image shown in the alpha and the comp.
