ABSTRACT:
A graphics device includes first and second endpoint memories where coordinates of a line can be stored. State logic within the graphics device calculates line parameters from the first and second endpoints. The calculated line parameters include a line error term which can be stored in an error term memory. The error term memory is writeable from a source external to the graphics device, such as the CPU of a computer system, so that the external source can modify the contents of the error term register.
