int gsline_ (x1, y1, x2, y2)
int *x1, *y1, *x2, *y2;
FORTRAN Syntax
INTEGER function gsline (x1, y1, x2, y2)
INTEGER x1, y1, x2, y2
Pascal Syntax
FUNCTION gsline_ (
VAR x1, y1, x2, y2: INTEGER
): INTEGER [PUBLIC|;
Description
The gsline subroutine draws a line, as defined by the
current relevant attributes, from the first point to the
second point defined by the parameters.
The relevant attributes are:
o Color map
o Plane mask
o Line color index
o Line style
o Logical operation.
Parameters
x1, y1 Defines the coordinates of one end
point of the line drawn by gsline.
x2, y2 Defines the coordinates of the second
point of the line drawn by gsline.
Return Value
GS_SUCC Successful.
GS_CORD Invalid coordinate.
GS_INAC Virtual terminal inactive.
