PaintArc

Fill a wedge with current pen pattern and mode

#include <Quickdraw.h> Quickdraw

void PaintArc( theRect, startAngle, arcAngle );

Rect *theRect ; rectangle defining position and size

short startAngle ; position where arc begins

short arcAngle ; extent of the arc

PaintArc draws and fills a wedge of an oval whose size is defined by a

rectangle. The figure is filled with the current pen pattern and transfer mode.

theRect is the address of an 8-byte Rect structure, defined in local

coordinates. It defines the size and position of the oval, of which the

arc is a subset.

startAngle specifies the starting position and . . .

arcAngle specifies the distance along the arc to be painted. See FrameArc

for a description of Quickdraw "rectangular degrees" and related

information and examples.

Notes: A wedge-shaped area is filled. Note that the "wedge" is actually any subset

of an oval:

Although Quickdraw does not provide a tool for drawing the outline of a

wedge, you can do so by painting (or filling) the wedge black, in setting

theRect , and then painting the smaller wedge white:

Rect theRect;

SetRect( & theRect, 100,100, 200,200 );

FillArc( & theRect, 0,45, black ); /* paint black */

InsetRect( & theRect, 10,10 ); /* make smaller oval */

FillArc( & theRect, 0,45, white ); /* interior is white */

PaintArc doesn't change the pen position.

As with all Quickdraw drawing, the output is clipped to the intersection of

the current GrafPort's BitMap boundary rectangle, the port rectangle,

clipping region, and visible region.
