NAME

Point, Line, MultiLine, S_MultiLine, SF_MultiLine - structured graphics classes for points, lines, and open polygons

SYNOPSIS

#include <Unidraw/Graphic/lines.h>

DESCRIPTION

Point and Line are subclasses of Graphic that draw a point and a line, respectively. MultiLine is a Vertices subclass that serves as an abstract base class for open polygons: S_MultiLine is a MultiLine subclass for stroked open polygons, while SF_MultiLine is a stroked-filled open polygon. Point, Line, and S_MultiLine store a PSBrush, while SF_MultiLine also stores a PSPattern.

POINT PUBLIC OPERATIONS

Point(Coord x, Cord y, Graphic* = nil): Construct a Point object, optionally supplying a graphic from which to obtain an initial set of graphics state.

void GetOriginal(Coord&, Coord&): Return the coordinates supplied in the constructor.

LINE PUBLIC OPERATIONS

Line(Coord x0, Cord y0, Coord x1, Coord y1, Graphic* = nil): Construct a Line object, optionally supplying a graphic from which to obtain an initial set of graphics state.

void GetOriginal(Coord& x0, Coord& y0, Coord& x1, Coord& y1): Return the line's endpoints as supplied in the constructor.

MULTILINE PROTECTED OPERATIONS

MultiLine(Coord* x, Coord* y, int count, Graphic* = nil): MultiLine's constructor is protected to prevent instantiation of the abstract base class. The parameters are passed directly to the Vertices constructor.

S_MULTILINE PUBLIC OPERATIONS

S_MultiLine(Coord* x, Coord* y, int count, Graphic* = nil): Construct an S_MultiLine object, optionally supplying a graphic from which to obtain an initial set of graphics state.

SF_MULTILINE PUBLIC OPERATIONS

SF_MultiLine(Coord* x, Coord* y, int count, Graphic* = nil): Construct an SF_MultiLine object, optionally supplying a graphic from which to obtain an initial set of graphics state.
