StdPoly

The default Quickdraw polygon-drawing routine

#include <Quickdraw.h> Quickdraw

void StdPoly(gVerb, thePoly );

GrafVerb gVerb ; frame, paint, erase, invert, or fill
PolyHandle thePoly ; handle leading to Polygon to draw

This is Quickdraw's default low-level routine for drawing polygons. The

polygon is framed, painted, erased, inverted, or filled, depending upon the

grafVerb.

gVerb is a GrafVerb enumerated-integer data type specifying the operation

to perform; it must be one of:

frame 0 draw the outline using current pen parameters

paint 1 fill with thePort->pnPat

erase 2 fill with thePort->bkPat

invert 3 toggle all bits enclosed by the object

fill 4 fill with thePort->fillPat

thePoly is a handle leading to a variable-length Polygon structure,

expressed in local coordinates, which defines the vertices of the

polygon to draw. See FramePoly for illustrations and related

information.

Notes: Use StdPoly only if your application intercepts the Quickdraw bottleneck

routines (see SetStdProcs).

All grafVerbs are performed using values taken from the current grafPort.

Output is clipped to portBits.bounds, portRect, visRgn, and clipRgn. This

function does not affect the pen position.

If a region is currently open and being formed (see OpenRgn), and

gVerb=frame, the polygon's interior is added to the region's structure. If

you're recording a picture (see OpenPicture), StdPoly incorporates the

polygon into its definition.
