Inside Macintosh: Imaging With QuickDraw /
Chapter 3 - QuickDraw Drawing / QuickDraw Drawing Reference
Routines / Drawing Ovals


To fill an oval with any available bit pattern, use the FillOval procedure.

PROCEDURE FillOval (r:\xDDRect; pat: Pattern);
The rectangle that defines the oval's boundaries.
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.
Using the patCopy pattern mode and the bit pattern defined in the Pattern record that you specify in the pat parameter, the FillOval procedure draws the interior of an oval just inside the bounding rectangle that you specify in the r parameter. The pen location does not change.

The FillOval procedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.

You can use the GetPattern and GetIndPattern routines, described on page 3-122 and page 3-123, respecively, to get a pattern stored in a resource. The patCopy pattern mode is described in "Boolean Transfer Modes With 1-Bit Pixels" beginning on page 3-7. The Pattern record is described on page 3-36.

You can use the PaintOval procedure, described in the previous section, to draw the interior of an oval with the pen pattern for the current graphics port. To fill an oval with a pixel pattern, use the FillCOval procedure, which is described in the chapter "Color QuickDraw."
