This function allows you to set the radius of the arc of any
raster shape which has rounded corners. These will then be equal no
matter what the size of the frame. To use it, click the number field,
use the [Esc] key to clear the field, set the desired radius, and
press the [Return] key. The unit of measure is selected as described
in Set units of measurement
. A value of 0.00
means that
the radii will be proportional to the frame size. Set radius works
with dynamic linking, as described above.
