Member Function Documentation

void imaging::OpenGlViewer::init	(	int	argc,
		char **	argv,
		const ublas::fixed_vector< float_t, 2 > &	lower_left,
		const ublas::fixed_vector< float_t, 2 > &	upper_right,
		size_t	window_width = STD_WINDOW_SIZE,
		size_t	window_height = STD_WINDOW_SIZE
	)			[virtual]

Initializes graphics. The arguments lower_left and upper_right specify the sections of the x-axis and the y-axis which are displayed, window_width and window_height the size of the output window.

Reimplemented from imaging::DummyGraphics.

void imaging::OpenGlViewer::clear

(

)

[virtual]

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

Reimplemented from imaging::DummyGraphics.

void imaging::OpenGlViewer::set_coordinates	(	const ublas::fixed_vector< float_t, 2 > &	lower_left,
		const ublas::fixed_vector< float_t, 2 > &	upper_right
	)			[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.

Reimplemented from imaging::DummyGraphics.

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

Draws the circle determined by center and radius.

See also:

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

Reimplemented from imaging::DummyGraphics.

References polygon().

void imaging::OpenGlViewer::polygon

(

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

vertices

)

[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.

polyline()

Reimplemented from imaging::DummyGraphics.

Referenced by circle().

void imaging::OpenGlViewer::fill_polygon

(

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

vertices

)

[virtual]

Fills the polygon determined by vertices with the current color.

Reimplemented from imaging::DummyGraphics.

void imaging::OpenGlViewer::polyline

(

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

vertices

)

[virtual]

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

See also:

polygon

Reimplemented from imaging::DummyGraphics.

void imaging::OpenGlViewer::vertex

(

const ublas::fixed_vector< float_t, 2 > &

vertex

)

[virtual]

Draws vertex as point on the drawing plane.

See also:

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

Reimplemented from imaging::DummyGraphics.

void imaging::OpenGlViewer::image	(	const ColorImage2d &	image,
		const ublas::fixed_vector< float_t, 2 >	x_interval,
		const ublas::fixed_vector< float_t, 2 >	y_interval
	)			[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 &)

Reimplemented from imaging::DummyGraphics.

Referenced by operator<<().

void imaging::OpenGlViewer::spline_curve

(

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

spline_curve

)

[virtual]

Draws the spline curve of order with knots and coefficient.

See also:

operator<<(gr & out, const Bspline< ublas::fixed_vector<float_t, 2> > &), operator<<(gr & out, const PeriodicBspline< ublas::fixed_vector<float_t, 2> > &), operator<<(gr & out, const BsplineShape & spline_shape)

Reimplemented from imaging::DummyGraphics.

GraphicsInterface & imaging::OpenGlViewer::operator<<

(

const CommandInterface &

command

)

[virtual]

Pass the stream command command to the stream.

Reimplemented from imaging::DummyGraphics.

References imaging::GraphicsInterface::set_color::color(), imaging::GraphicsInterface::set_group::group_id(), image(), imaging::GraphicsInterface::set_line_width::line_width(), imaging::GraphicsInterface::offset_z_layer::offset(), and imaging::GraphicsInterface::translate::translation().

virtual const StreamStatus& imaging::OpenGlViewer::get_stream_status

(

)

[inline, virtual]

Get the current stream status. Use this function to backup the status and restore it later. The status of a stream is determined by its

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

Reimplemented from imaging::DummyGraphics.

virtual void imaging::OpenGlViewer::write_image	(	const std::string &	file_name,
		const int	image_format = IMAGE_FORMAT_DETERMINE
	)			[inline, virtual]

Write the content of the graphics output to an image file. The file format of the output image is determined by image_format. The size of the image will be the current size of the coordinate axes.

Reimplemented from imaging::DummyGraphics.

void imaging::OpenGlViewer::write_image	(	const std::string &	file_name,
		size_t	width,
		size_t	height,
		const int	image_format = IMAGE_FORMAT_DETERMINE
	)			[virtual]

Write the content of the graphics output to an image file. The file format of the output image is determined by image_format. The size of the image is determined by width and height.

Reimplemented from imaging::DummyGraphics.
