FillArc
To fill a wedge with any available bit pattern, use theFillArc
procedure.
PROCEDURE FillArc (r:\xDDRect; startAngle,arcAngle: Integer; pat: Pattern);
r
- The rectangle that defines an oval's boundaries.
startAngle
The angle indicating the start of the arc.arcAngle
- The angle indicating the arc's extent.
pat
- 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.
DESCRIPTION
Using thepatCopy
pattern mode and the pattern defined in thePattern
record that you specify in thepat
parameter, theFillArc
procedure draws a wedge of the oval bounded by the rectangle that you specify in ther
parameter. As in theFrameArc
procedure described on page 3-68 and as illustrated in Figure 3-21, use thestartAngle
andarcAngle
parameters to define the arc of the wedge.This procedure leaves the location of the graphics pen unchanged.
SPECIAL CONSIDERATIONS
TheFillArc
procedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.SEE ALSO
You can use theGetPattern
andGetIndPattern
routines, described on page 3-122 and page 3-123, respectively, to get a pattern stored in a resource. ThepatCopy
pattern mode is described in "Boolean Transfer Modes With 1-Bit Pixels" beginning on page 3-7. ThePattern
record is described on page 3-36.You can use the
PaintArc
procedure, 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 theFillCArc
procedure, which is described in the chapter "Color QuickDraw."
