virtual void imaging::GraphicsInterface::clear

(

)

[pure virtual]

Clears the graphics output. All groups are reset and all objects removed from the window.

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

virtual void imaging::GraphicsInterface::set_coordinates	(	const ublas::fixed_vector< float_t, 2 > &	lower_left,
		const ublas::fixed_vector< float_t, 2 > &	upper_right
	)			[pure virtual]

Initializes the coordinate system of the graphics output. The arguments lower_left and upper_right specify the sections of the x-axis and the y-axis which are displayed.

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

void imaging::GraphicsInterface::line_segment	(	const ublas::fixed_vector< float_t, 2 > &	v_0,
		const ublas::fixed_vector< float_t, 2 > &	v_1
	)

Draws the line segment determined by v_0 and v_1.

References polyline().

Referenced by arrow().

void imaging::GraphicsInterface::arrow	(	const ublas::fixed_vector< float_t, 2 > &	starting_point,
		const ublas::fixed_vector< float_t, 2 > &	direction
	)

Draws the vector direction at starting_point and adds an arrowhead.

References line_segment(), imaging::PI, and imaging::rotation_matrix().

void imaging::GraphicsInterface::quadrangle	(	const ublas::fixed_vector< float_t, 2 > &	v_0,
		const ublas::fixed_vector< float_t, 2 > &	v_1,
		const ublas::fixed_vector< float_t, 2 > &	v_2,
		const ublas::fixed_vector< float_t, 2 > &	v_3
	)

Draws the quadrangle determined by v_0, v_1, v_2 and v_3.

References polygon().

void imaging::GraphicsInterface::triangle	(	const ublas::fixed_vector< float_t, 2 > &	v_0,
		const ublas::fixed_vector< float_t, 2 > &	v_1,
		const ublas::fixed_vector< float_t, 2 > &	v_2
	)

Draws the triangle determined by v_0, v_1 and v_2.

References polygon().

virtual void imaging::GraphicsInterface::circle	(	const ublas::fixed_vector< float_t, 2 > &	center,
		float_t	radius
	)			[pure virtual]

Draws the circle determined by center and radius.

See also:

operator<<(gr & out, const Circle & circle)

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

Referenced by imaging::operator<<().

virtual void imaging::GraphicsInterface::polygon

(

const std::vector< ublas::fixed_vector< float_t, 2 > > &

vertices

)

[pure virtual]

Draws the polygon determined by vertices. The first and the last point in vertices will automatically be connected, i.e. there is no need for them to be the same.

See also:

polyline()

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

Referenced by imaging::operator<<(), quadrangle(), and triangle().

virtual void imaging::GraphicsInterface::fill_polygon

(

const std::vector< ublas::fixed_vector< float_t, 2 > > &

vertices

)

[pure virtual]

Fills the polygon determined by vertices with the current color.

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

virtual void imaging::GraphicsInterface::polyline

(

const std::vector< ublas::fixed_vector< float_t, 2 > > &

vertices

)

[pure virtual]

Draws the polyline determined by vertices. The first and the last point in vertices will not be connected.

See also:

polygon

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

Referenced by line_segment(), and imaging::operator<<().

virtual void imaging::GraphicsInterface::vertex

(

const ublas::fixed_vector< float_t, 2 > &

vertex

)

[pure virtual]

Draws vertex as point on the drawing plane.

See also:

operator<<(gr & out, const ublas::fixed_vector<float_t, 2> &)

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

Referenced by imaging::operator<<().

virtual void imaging::GraphicsInterface::image	(	const ColorImage2d &	image,
		const ublas::fixed_vector< float_t, 2 >	x_interval,
		const ublas::fixed_vector< float_t, 2 >	y_interval
	)			[pure virtual]

Rescales image such that it fits into the rectangle x_interval x y_interval and draws it.

See also:

operator<<(gr & out, const ColorImage2d &)

Implemented in imaging::DummyGraphics, and imaging::OpenGlViewer.

Referenced by imaging::operator<<().

virtual void imaging::GraphicsInterface::spline_curve

(

const Bspline< ublas::fixed_vector< float_t, 2 > > &

spline_curve

)

[pure virtual]

Draws the spline curve of order with knots and coefficient.

const StreamStatus &

status

)

[pure virtual]

• color,
• group,
• z_value,
• translation, and
• line width.
