Polar Coordinates
Edit workspace
The Polar Coordinates effect changes pixels by mapping them from
Cartesian to polar coordinates, or from polar to Cartesian coordinates.
You can access the Polar Coordinates dialog box by choosing Effects
Distortion Effects Polar Coordinates.
The Polar Coordinates dialog box contains the following controls:
• Rectangular to polar — maps pixels from Cartesian to polar
coordinates
• Polar to rectangular — maps pixels from polar to Cartesian
coordinates
• Wrap — makes the image appear as though it were a tile
repeating in each direction
• Repeat — finds the edge pixel of each side and repeats it outward
infinitely
• Color — lets you choose a color to represent out-of-bounds pixels.
You can click the color box to access the Color dialog box, or right-
click the color box to access the Recent Colors dialog box.
• Transparent — makes out-of-bounds pixels transparent.
