How to get regions to plot as graphics
3
$begingroup$
I want to put an anulus in my graphics object. How can I format a region difference into a graphics primitive?
a=1;b=5;
Region[RegionDifference[Disk[{0,0},b],Disk[{0,0},a]]] (*works*)
Graphics[{Rectangle[{5,5}], Blue,Rectangle[{-5,-5}],RegionDifference[Disk[{0,0},b],Disk[{0,0},a]]}](*doesn't work*)
Head[RegionDifference[Disk[{0,0},b],Disk[{0,0},a]]] (* wrong object type *)
Head[Disk]
graphics regions
