Detailed Description

A triangle with shaded filling according to colors given for each vertex.

The GouraudTriangle structure.

Member Function Documentation

◆ clone()

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

overridevirtual

Return a copy of the shape.

Returns: A copy of the shape.

Reimplemented from LibBoard::Polyline.

◆ flushFIG()

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

overridevirtual

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
colormap

Reimplemented from LibBoard::Polyline.

References LibBoard::Polyline::flushFIG().

◆ flushPostscript()

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

overridevirtual

Sends the triangle to a Postscript document.

Parameters

stream
transform

Reimplemented from LibBoard::Polyline.

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

Referenced by flushPostscript().

◆ flushSVG()

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

overridevirtual

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

Referenced by flushSVG().

◆ flushTikZ()

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

overridevirtual

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.

◆ name()

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

overridevirtual

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

Returns

Reimplemented from LibBoard::Polyline.

◆ resized()

GouraudTriangle LibBoard::GouraudTriangle::resized	(	double	w,
		double	h,
		LineWidthFlag	lineWidthFlag
	)		const

Returns a resized copy of the triangle.

Parameters

w	Width of the new triangle.
h	Height of the new triangle.
lineWidthFlag	Should the line width be considered when computing bounding boxes.

Returns: A resized copy of the triangle.

◆ rotate() [1/2]

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

overridevirtual

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 LibBoard::Shape::center(), and rotate().

◆ rotate() [2/2]

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

overridevirtual

Rotate the shape around a given center of rotation.

Parameters

angle	The rotation angle in radian.
center	The center of rotation.

Returns: A reference to the shape itself.

Reimplemented from LibBoard::Polyline.

References LibBoard::Shape::center(), and rotate().

◆ scaleAll()

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

overridevirtual

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

Parameters

s	The scaling factor.

Reimplemented from LibBoard::Polyline.

◆ scaled() [1/2]

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().

◆ scaled() [2/2]

GouraudTriangle LibBoard::GouraudTriangle::scaled	(	double	sx,
		double	sy
	)		const

Returns a scaled copy of the triangle.

Parameters

sx	Scaling factor along the x axis.
sy	scaling factor along the y axis.

	)		const

Returns a translated copy of the triangle.

Parameters

dx	The shift along the x axis.
dy	The shift along the y axis.

Returns: A translated copy of the triangle.
