FillArcTo fill a wedge with any available bit pattern, use the
PROCEDURE FillArc (r:ÝRect; startAngle,arcAngle: Integer; pat: Pattern);
- The rectangle that defines an oval's boundaries.
The angle indicating the start of the arc.
- The angle indicating the arc's extent.
- The bit pattern to use for the fill. Figure 3-3 on page 3-6 illustrates the default fill patterns and the constants you can use to represent them.
patCopypattern mode and the pattern defined in the
Patternrecord that you specify in the
FillArcprocedure draws a wedge of the oval bounded by the rectangle that you specify in the
rparameter. As in the
FrameArcprocedure described on page 3-68 and as illustrated in Figure 3-21, use the
arcAngleparameters to define the arc of the wedge.
This procedure leaves the location of the graphics pen unchanged.
FillArcprocedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.
SEE ALSOYou can use the
GetIndPatternroutines, described on page 3-122 and page 3-123, respectively, to get a pattern stored in a resource. The
patCopypattern mode is described in "Boolean Transfer Modes With 1-Bit Pixels" beginning on page 3-7. The
Patternrecord is described on page 3-36.
You can use the
PaintArcprocedure, described in the previous section, to draw a wedge with the pen pattern for the current graphics port. To fill a wedge with a pixel pattern, use the
FillCArcprocedure, which is described in the chapter "Color QuickDraw."
