Radar
Source plugin to simulate a radar sweep. Useful as a key mask.

PARAMETERS

  1. Speed
    auto-rotation rate: 0 = none, 1 = max
  2. Decay
    sweep width: 0 = min, .5 = fit to frame, 1 = max
  3. Radius
    sweep radius: 0 = min, 1 = max
  4. Color
    selects sweep color: white, R, G, B, C, M, Y
  5. Origin X
    sweep origin X: 0 = left, 1 = right
  6. Origin Y
    sweep origin Y: 0 = top, 1 = bottom
  7. Angle
    angle: 0 = 0 degrees, 1 = 360 degrees
  8. Scale
    radius scaling: 0 = none, 1 = max
  9. Reverse
    if non-zero, reverse sweep direction

Assembler optimized. Supports 32-bit color only.
The Angle parameter is more useful with auto-rotate off (Speed = 0).
The Scale parameter is useful for ensuring that the sweep fills the
entire frame, e.g. if the frame has an unusual aspect ratio, or the
origin is moved to a corner of the frame. The fit to frame behavior
(Radius = .5) assumes Scale = 0.
