Detailed Description

The GouraudTriangle structure.

Member Function Documentation

Point LibBoard::GouraudTriangle::center ( ) const

virtual

Returns the center of the shape.

Returns: The center of the shape, i.e. the center of its bounding box.

Reimplemented from LibBoard::Polyline.

References LibBoard::Path::center().

Referenced by rotate().

GouraudTriangle * LibBoard::GouraudTriangle::clone ( ) const

virtual

Return a copy of the shape.

Returns: A copy of the shape.

Reimplemented from LibBoard::Polyline.

void LibBoard::GouraudTriangle::flushFIG	(	std::ostream &	stream,
		const TransformFIG &	transform,
		std::map< Color, int > &	colormap
	)		const

virtual

Sends the Triangle to a FIG file format stream.

Warning! Because shading would generally require more colors in the colormap than allowed by the FIG file format, rendering a Gouraud triangle in an XFig file is the same as rendering a simple triangle whose filling color is the average of the vertex colors.

Parameters

stream
transform
Color
colormap

Reimplemented from LibBoard::Polyline.

References LibBoard::Polyline::flushFIG().

void LibBoard::GouraudTriangle::flushPostscript	(	std::ostream &	stream,
		const TransformEPS &	transform
	)		const

virtual

Sends the triangle to a Postscript document.

Parameters

stream
transform

Reimplemented from LibBoard::Polyline.

References LibBoard::Shape::_depth, LibBoard::Polyline::flushPostscript(), flushPostscript(), LibBoard::Point::x, and LibBoard::Point::y.

Referenced by flushPostscript().

void LibBoard::GouraudTriangle::flushSVG	(	std::ostream &	stream,
		const TransformSVG &	transform
	)		const

virtual

Write the SVG code of the shape in a stream according to a transform.

Parameters

stream	The output stream.
transform	A 2D transform to be applied.

Reimplemented from LibBoard::Polyline.

References LibBoard::Shape::_depth, LibBoard::Polyline::flushSVG(), flushSVG(), LibBoard::Point::x, and LibBoard::Point::y.

Referenced by flushSVG().

void LibBoard::GouraudTriangle::flushTikZ	(	std::ostream &	stream,
		const TransformTikZ &	transform
	)		const

virtual

Write the TikZ code of the shape in a stream according to a transform.

Parameters

stream	The output stream.
transform	A 2D transform to be applied.

Reimplemented from LibBoard::Polyline.

const std::string & LibBoard::GouraudTriangle::name ( ) const

virtual

Returns the generic name of the shape (e.g., Circle, Rectangle, etc.)

Returns

Reimplemented from LibBoard::Polyline.

GouraudTriangle & LibBoard::GouraudTriangle::rotate	(	double	angle,
		const Point &	center
	)

virtual

Referenced by rotate().

GouraudTriangle & LibBoard::GouraudTriangle::rotate ( double angle )

virtual

Rotate the shape around its center.

Parameters

angle The rotation angle in radian.

Returns: A reference to the shape itself.

Reimplemented from LibBoard::Polyline.

References center(), and rotate().

void LibBoard::GouraudTriangle::scaleAll ( double s )

virtual

Scales all the values (positions, dimensions, etc.) associated with the shape.

Parameters

s	The scaling factor.

GouraudTriangle LibBoard::GouraudTriangle::scaled ( double s ) const

Returns a scaled copy of the triangle.

Parameters

s	The scaling factor.

Returns: A scaled copy of the tiangle.

References LibBoard::Polyline::scale().

GouraudTriangle LibBoard::GouraudTriangle::translated	(	double	dx,
		double	dy
	)		const

Returns a translated copy of the triangle.

Parameters
