Polygon Spiral
What is it ? : This transform draw a spiral of arbitrary regular polygons. The polygon are rotated of a definite angle at each iteration and are sized such as the vertices of each lie on the sides of the previous one (ie they are in a way "tangent" to each other). The Parameters : Mode :
Order : The number of side of the regular polygon. Angle step : The angle the polygon will be rotated at each iteration. Mapping Center/Rotation/Magnification : To specify which part of the underlying image will be mappped on the polygons. Color Number : The number of colors used in the "Color" mode (see above). Outside : How the outside of the first polygon will look like. "Standard"
diplay the underlying image and "Solid" assign solid color to outside points.
"Old" is kept for backward compatibility.
