TYPE: COP
TITLE: Ramp COP

This COP generates a variety of linear and radial ramps, which are fully
keyframable. This COP is easily manipulated using the viewport (see prompts).

Parameters:
Ramp
    Ramp                    - The type of ramp to generate.
	Horizontal - Ramp is linear with points horizontally.
	Vertical   - Ramp is linear with points vertically.
	Radial     - Ramp is circular with points extending radially.
	Concentric - Ramp is circular with points at varying distances
                     from the center.
    Global Interpolation     - The interpolation between ramp point which
			       is used by default. Individual points may
			       override this interpolation.
	Step             - The segment is constant valued.
	Linear           - The segment is linearly interpolated between
			   the two point colors.
	Ease In          - The segment drops off quickly from the first
			   value and eases into the second.
	Ease Out         - The segment eases out of the first value
			   and drops quickly to the second.
	Ease In Ease Out - The segment eases into both values.

    Number of Cycles         - The number of cycles to repeat the ramp for.
    Phase                    - The phase (0-1) to offset the ramp.
    Rotation                 - Rotates the ramp.
    Center                   - Specifies the center of the ramp for radial
			       and concentric ramps.
    Wrap First To Last       - If on, an implicit segment is created 
			       between the last and first points. 
			       Otherwise, the value of the first and last
			       ramp points is held before or after the ramp
			       point range.
    Repeat Ramp              - For a concentric ramp, this will repeat the
			       ramp continually if on. Otherwise, only 1
			       cycle is used.
Points
    Point N                  - If on, this point is included in the ramp at
			       the U coordinate specified.
    Color                    - The color of the ramp point. Values may be
			       less than zero or greater than 1.
    Segement N Interpolation - By default, the global interpolation is
			       used. This can override the interpolation to
			       give a segement a specific interpolation.
Image & Sequence
    Overview - See extra help (Middle click on the dialog '?' help).

Local Variables:
    L   - Sequence length
    S   - Start of sequence

    W,H - Width and height of image
    I   - Image index (0 at start frame)
    IT  - Image time (0 at start frame)
    AI  - Current plane array index
    PI  - Current plane index
    PC  - Num of channels in current plane
