Abstract
Line draw circuitry receives parameters defining first and second endpoints of a line and calculates line parameters based on the first and second endpoints. The line parameters are then stored in a memory. A "calculate-only" control signals determines whether a line is drawn immediately after calculation (and storing) of the end parameters or whether the line is drawn responsive to a subsequent "start" signal. If the line is to be drawn responsive to the start signal, the line parameters may be modified prior to drawing the line.
