Purpose
Draws a filled rectangle.
C Syntax
int gsfrec_ (x1, y1, x2, y2)
int *x1, *y1, *x2, *y2;
FORTRAN Syntax
INTEGER function gsfrec (x1, y1, x2, y2)
INTEGER x1, y1, x2, y2
Pascal Syntax
FUNCTION gsfrec_ (
VAR x1, y1, x2, y2: INTEGER
): INTEGER [PUBLIC|;
Description
The gsfrec subroutine fills the rectangular area defined
by the lower leftmost and upper rightmost coordinate
parameters, with the color determined by the last call to
the gsfatt subroutine.
The relevant attributes are:
o Color map
o Plane mask
o Fill color index
o Fill pattern index
o Logical operation.
Parameters
x1, y1 Define the lower left corner of the rectangular
area to fill.
x2, y2 Define the upper right corner of the rectan-
gular area to fill.
The edges of the rectangle are treated as part of the
area to be filled.
The fill pattern does not meet the border of the filled
area on printers and plotters.
Return Value
GS_SUCC Successful.
GS_CORD Invalid coordinate.
GS_INAC Virtual terminal inactive.
