Geometry
Polar
A move into polar coordinates: rows become rings.
Controls
- mode
- To-polar rolls the rectangle into a circle — a column becomes a ray, a row a ring. From-polar unrolls it back
- center X
- A number from 0 to 1, 0.5 by default.
- center Y
- A number from 0 to 1, 0.5 by default.
- rotation
- Turns the picture around the centre. Positive goes clockwise, with zero pointing up
- repeat
- How many times the picture goes round the circle. Whole numbers only, or the seam at the full turn would not meet
- zoom
- Radius of the circle against the frame. At one it fits inside; higher pushes it past the corners, lower pulls it into a rosette
