Ramp Effect; Scribble Effect; Controls For The Scribble Effect - Adobe AFTER EFFECTS 7.0 Manual

Ramp effect

The Ramp effect creates a color gradient, blending it with the original image contents. Create linear or radial ramps,
and vary the position and colors of the ramp over time. Use the Start Of Ramp and End Of Ramp controls to specify
the start and end positions. Use the Ramp Scatter control to disperse the ramp colors and eliminate banding.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.

Note: Ramps often do not broadcast well; serious banding occurs because the broadcast chrominance signal does not
contain sufficient resolution to reproduce the ramp smoothly. The Ramp Scatter control disperses the ramp colors, elimi-
nating the banding apparent to the human eye.

Scribble effect

The Scribble effect creates the appearance of hand-drawn artwork by replacing a closed mask shape with strokes.
For example, Scribble can simulate fills that look like marker, cross-hatching, or textiles. Scribble replaces a mask
shape with a single zigzagging line that criss-crosses the path. Some paths, because of their geometry, cannot be filled
with a single line. Scribble breaks these paths into several simpler paths, each of which it then fills with a zigzagged
stroke.
This effect works with 8-bpc color.

Controls for the Scribble effect

Specifies the mask you want to use for the Scribble effect. Single Mask scribbles a specified mask on the
Scribble
layer; All Masks scribbles all masks on the layer; All Masks Using Modes combines the masks using their modes and
then scribbles the resulting shape.
Specifies the mask to use for the effect. It is enabled if Scribble is set to Single Mask.
Mask
Controls whether the fill is drawn inside the path or creates a scribble along the path. Left Edge draws the
Fill Type
fill along the path's left edge; Right Edge draws the fill along the path's right edge. The left and right edges of a path
are determined by the direction in which the path is drawn. From start to end of the path, the left edge is on the left,
and the right edge is on the right. When using the Left Edge or Right Edge fill types on masks that have tight curves,
you get best results by making the Edge Width less than the radius of the curve.
Specifies the options for the edge of the scribble. It is enabled if Fill Type is set to an edge.
