An affine transformation UGen for image rotation, scaling, translation, shearing.
It uses either a sinc-based band-limited resampling algorithm, or
bicubic interpolation, depending on the zeroCrossings parameter.
All window defining parameters (widthIn, heightIn, widthOut, heightOut)
are polled once per matrix. All matrix and filter parameters are polled one per
output pixel.
- Value parameters:
- heightIn
the height (number of rows) of the input matrix
- heightOut
the height (number of rows) of the output matrix. the special value zero (default) means it is the same as
heightIn.- in
the signal to resample
- kaiserBeta
the FIR windowing function's parameter
- m00
coefficient of the first column of the first row (scale-x)
- m01
coefficient of the second column of the first row (shear-x)
- m02
coefficient of the third column of the first row (translate-x)
- m10
coefficient of the first column of the second row (shear-y)
- m11
coefficient of the second column of the second row (scale-y)
- m12
coefficient of the third column of the second row (translate-y)
- rollOff
the FIR anti-aliasing roll-off width. Between zero and one.
- widthIn
the width (number of columns) of the input matrix
- widthOut
the width (number of columns) of the output matrix. the special value zero (default) means it is the same as
widthIn.- wrap
if non-zero, wraps coordinates around the input images boundaries. TODO: currently
wrap = 0is broken if using sinc interpolation!- zeroCrossings
the number of zero-crossings in the truncated and windowed sinc FIR. If zero, algorithm uses bicubic interpolation instead.
