gsfell
PURPOSE
Fills an ellipse.
C SYNTAX
int gsfell_ (cx, cy, ma, mi, ang)
int *cx, *cy, *ma, *mi, *ang;
FORTRAN SYNTAX
INTEGER function gsfell (cx, cy, ma, mi, ang)
INTEGER cx, cy, ma, mi, ang
PASCAL SYNTAX
FUNCTION gsfell_ (
VAR cx, cy, ma, mi, ang : INTEGER
): INTEGER [PUBLIC];
DESCRIPTION
The gsfell subroutine fills an ellipse of the specified axes and angle. The
axes are expressed in number of pixels.
The angle specifications are given in tenths of degrees, from 0 to 3600.
Values outside this range cause the gsfell subroutine to fail.
The relevant attributes are:
o Color map
o Plane mask
o Fill color index
o Fill pattern index
o Logical operation.
Parameters
cx, cy Define the coordinates of the center of the ellipse.
ma, mi Define half of the nonzero major and minor axes of the ellipse.

ang Defines the angle between the major axis and the x-axis. If it is 0,
the major axis is on the x-axis and the minor axis is on the y-axis.
The angle is defined in tenths of degrees, from 0 to 3600, specified
in a counterclockwise direction.
RETURN VALUE
GS_SUCC Successful.
GS_CORD Invalid coordinate.
GS_ELMM Invalid major or minor axis.
GS_INAC Virtual terminal inactive.
GS_ANGL Invalid angle.
GS_NMEM Insufficient resources.
