Graphics::Grid::Grob::Segments - Line segments grob

VERSION

version 0.0001

SYNOPSIS

    use Graphics::Grid::Grob::Segments;
    use Graphics::Grid::GPar;
    my $lines = Graphics::Grid::Grob::Segments->new(
            x0 => 0, y0 => 0,
            x1 => 1, y1 => 1,
            gp => Graphics::Grid::GPar->new()
    );

    # or use the function interface
    use Graphics::Grid::Functions qw(:all);
    my $lines = segments_grob(%params);

DESCRIPTION

This class represents a "line segments" graphical object. It's a little bit similar to Graphics::Grid::Grob::Polyline in that a segments grob can also be implemented by a ployline grob.

ATTRIBUTES

x0

A Graphics::Grid::Unit object specifying the starting x-values of the line segments.

y0

A Graphics::Grid::Unit object specifying the starting y-values of the line segments.

x1

A Graphics::Grid::Unit object specifying the stopping x-values of the line segments.

y1

A Graphics::Grid::Unit object specifying the stopping y-values of the line segments.

gp

An object of Graphics::Grid::GPar. Default is an empty gpar object.

vp

A viewport object. When drawing a grob, if the grob has this attribute, the viewport would be temporily pushed onto the global viewport stack before drawing takes place, and be poped after drawing. If the grob does not have this attribute set, it would be drawn on the existing current viewport in the global viewport stack.

elems

Get number of sub-elements in the grob.

Grob classes shall implement a _build_elems() method to support this attribute.

For this module elems always returns 1.
