Centre:
Centre of the spin effect.
Diameter:
Maximum distance from the centre for the

will not
be affected.
Enable Wave Period:
If enabled, the image is rotated with variable angular distance. The
distance varies in a sine wave pattern.
Wave Period:
Number of periods in the distance
wave.
Background Colour:
Specifies the colour used when the transform goes beyond the
image data.
Quality:
Specifies the quality of transformed image. In
low Quality mode no interpolation is used. When medium, bi-linear interpolation is used and for best quality mode bi-cubic
interpolation is used. Processing time also increases as the quality of
transform is increased. |
