PrectMode
processing
Modifies the location from which rectangles are drawn by changing the way in which parameters given to Prect are intepreted.
The default mode is CORNER, which interprets the first two parameters of Prect as the upper-left corner of the shape, while the third and fourth parameters are its width and height.
CORNERS interprets the first two parameters of Prect as the location of one corner, and the third and fourth parameters as the location of the opposite corner.
CENTER interprets the first two parameters of Prect as the shape's center point, while the third and fourth parameters are its width and height.
RADIUS also uses the first two parameters of Prect as the shape's center point, but uses the third and fourth parameters to specify half of the shape's width and height.
The parameter must be written in ALL CAPS because Processing is a case-sensitive language.
