Member Function Documentation

begin()

virtual void bpp::GraphicDevice::begin ( )

pure virtualinherited

Start the painting.

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.

comment()

virtual void bpp::GraphicDevice::comment ( const std::string &  comment )

pure virtualinherited

Add a comment in the output.

Parameters

comment

Comment text.

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.

drawCircle()

virtual void bpp::GraphicDevice::drawCircle ( double  x, double  y, double  radius, short  fill = FILL_EMPTY  )

pure virtualinherited

Draw a circle.

This method uses the current foreground color and the current line type for drawing the stroke of the circle, and the current background color for filling the circle.

Parameters

x	x coordinate of the center
y	y coordinate of the center
radius	The circle radius
fill	Filling type (one of FILL_EMPTY, FILL_FILLED or FILL_PATTERN).

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.

drawLine()

virtual void bpp::GraphicDevice::drawLine ( double  x1, double  y1, double  x2, double  y2  )

pure virtualinherited

Draw a line between two points.

This method uses the current foreground color and the current line type.

Parameters

x1	x coordinate 1
y1	y coordinate 1
x2	x coordinate 2
y2	y coordinate 2

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.

drawRect()

virtual void bpp::GraphicDevice::drawRect ( double  x, double  y, double  width, double  height, short  fill = FILL_EMPTY  )

pure virtualinherited

Draw a rectangle.

This method uses the current foreground color and the current line type for drawing the stroke of the rectangle, and the current background color for filling the rectangle.

Parameters

x	x coordinate
y	y coordinate
width	The rectangle width
height	The rectangle height
fill	Filling type (one of FILL_EMPTY, FILL_FILLED or FILL_PATTERN).

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.

drawText()

virtual void bpp::GraphicDevice::drawText ( double  x, double  y, const std::string &  text, short  hpos = TEXT_HORIZONTAL_LEFT, short  vpos = TEXT_VERTICAL_BOTTOM, double  angle = 0  )

pure virtualinherited

Draw some characters.

This method uses the current foreground color.

Parameters

x	x coordinate
y	y coordinate
text	The characters to draw
hpos	Horizontal adjustment, one of TEXT_HORIZONTAL_LEFT, TEXT_HORIZONTAL_CENTER or TEXT_HORIZONTAL_RIGHT.
vpos	Vertical adjustment, one of TEXT_VERTICAL_LEFT, TEXT_VERTICAL_CENTER or TEXT_VERTICAL_RIGHT.
angle	Angle i radian to rotate the text.

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.

end()

virtual void bpp::GraphicDevice::end ( )

pure virtualinherited

End the painting.

Depending on the implementation of the device, the call of this method might be required before the plotting commands become visible.

Implemented in bpp::XFigGraphicDevice, bpp::PgfGraphicDevice, and bpp::SvgGraphicDevice.
