void GrArcAngle ( GR_DRAW_ID id, GR_GC_ID gc, GR_COORD x, GR_COORD y, GR_SIZE rx, GR_SIZE ry, GR_COORD angle1, GR_COORD angle2, int type );
The ID of the window or other drawable area.
The graphics context to use when drawing the arc.
The center of the arc relative to the drawable area.
The radii of the arc.
The starting and ending angles of the arc specified in 64ths of a degree. For example, to specify 25.5 degrees, you would use 1632 (25.5 x 64).
The method of drawing the arc. The type parameter has the following acceptable values:
The GrArcAngle function draws an arc with its center at (x, y) and horizontal radius of rx and a vertical radius of ry. The function drawing the arc from angle1 to angle2.
Note: You must have a platform with a floating point processor to use the GrArcAngle function. If you do not have a floating point processor, Use the GrArc function instead.
