ScanImage

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 = 0 is 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.
