PellipseMode
processingModifies the location from which ellipses are drawn by changing the way in which parameters given to Pellipse
are intepreted.
The default mode is ellipseMode(CENTER), which interprets the first two parameters of Pellipse
as the shape's center point, while the third and fourth parameters are its width and height.
ellipseMode(RADIUS) also uses the first two parameters of Pellipse
as the shape's center point, but uses the third and fourth parameters to specify half of the shapes's width and height.
ellipseMode(CORNER) interprets the first two parameters of Pellipse
as the upper-left corner of the shape, while the third and fourth parameters are its width and height.
ellipseMode(CORNERS) interprets the first two parameters of Pellipse
as the location of one corner of the ellipse's bounding box, and the third and fourth parameters as the location of the opposite corner.
