81
<span class="term">Circle Depth in Percent</span>

86
rectangle (0%) to circle (100%).
90
<span class="term">Offset Angle</span>
94
This option controles the angle the drawing will start from (0 - 359°), and so turns it
95
around the circle center.
99
<span class="term">Map Backwards</span>
103
When this option is checked, the drawing will start from the right instead of the left.
107
<span class="term">Map from Top</span>
111
If unchecked, the mapping will put the bottom row in the middle and the top row on the
112
outside. If checked, it will be the opposite.
116
<span class="term">To Polar</span>
120
If unchecked, the image will be circularly mapped into a rectangle (odd effect). If checked,
121
the image will be mapped into a circle.
