final case class ScanImage(in: D, width: I, height: I, x: D = 0, y: D = 0, next: B = false, wrap: I = 0, rollOff: D = 0.86, kaiserBeta: D = 7.5, zeroCrossings: I = 0) extends SingleOut[Double] with Product with Serializable
A UGen that scans the pixels of an image using an x and y input signal.
It uses either a sinc-based band-limited resampling algorithm, or
bicubic interpolation, depending on the zeroCrossings parameter.
All window defining parameters (width, height)
are polled once per matrix. All scanning and filter parameters are polled one per
output pixel.
- in
the image to scan
- width
the width (number of columns) of the input matrix
- height
the height (number of rows) of the input matrix
- x
horizontal position of the dynamic scanning signal
- y
vertical position of the dynamic scanning signal
- next
a trigger that causes the UGen to read in a new image from
in.- wrap
if non-zero, wraps coordinates around the input images boundaries. TODO: currently
wrap = 0is broken if using sinc interpolation!- rollOff
the FIR anti-aliasing roll-off width. Between zero and one.
- kaiserBeta
the FIR windowing function's parameter
- zeroCrossings
the number of zero-crossings in the truncated and windowed sinc FIR. If zero (default), algorithm uses bicubic interpolation instead.
