2.4 Graphics Protocols
2.4.1 Arguments
- All these generic functions take the same arguments as the non-generic spread function equivalents, except that the arguments that are keyword arguments in the non-generic functions are required arguments in the generic functions.
- The drawing-function-specific arguments are either x and y positions, or a sequence of x and y positions. Note that these positions will first be transformed by the medium's current transformation, and then transformed a second time by the medium's device transformation in order to produce the coordinates as they will actually appear on the screen.
- The ink, line style (or text style), and clipping regions arguments are optional, and default from the medium (medium-ink, medium-line-style (or medium-current-text-style), and medium-clipping-region, respectively).
