Member Function Documentation

void NewCanvas	(	double	width,
		double	height
	)			[virtual]

Create a new canvas to paint on with size width x height. OBDepict will always call NewCanvas before performing any drawing operations. Painters that are capable of drawing on a previously unspecified area don't need to implement this.

Implements OBPainter.

bool IsGood

(

)

const [virtual]

Before OBDepict performes any drawing operation, this method is called to check if the painter is ready to start drawing. If this method returns false, drawing is aborted.

Implements OBPainter.

void SetFontFamily

(

const std::string &

fontFamily

)

[inline, virtual]

Set the painter's font family.

Implements OBPainter.

void SetFontSize

(

int

pointSize

)

[virtual]

Set the painter's font point size.

Implements OBPainter.

Referenced by CairoPainter::NewCanvas().

void SetFillColor

(

const OBColor &

color

)

[virtual]

Set the painter's fill color.

Implements OBPainter.

void SetPenColor

(

const OBColor &

color

)

[virtual]

Set the painter's pen color.

Implements OBPainter.

Referenced by CairoPainter::NewCanvas().

void SetPenWidth

(

double

width

)

[virtual]

Set the painter's pen width.

Implements OBPainter.

void DrawLine	(	double	x1,
		double	y1,
		double	x2,
		double	y2
	)			[virtual]

Draw a line from x1, y1 to x2, y2. The line is drawn using the current pen color and width.

Implements OBPainter.

void DrawPolygon

(

const std::vector< std::pair< double, double > > &

points

)

[virtual]

Draw a polygon by connecting consecutive points. The last point will be connected to the first one. The lines are drawn using the current pen color and width. The area inside the polygon is filled with the current fill color.

Implements OBPainter.

void DrawCircle	(	double	x,
		double	y,
		double	r
	)			[virtual]

Implements OBPainter.

void DrawText	(	double	x,
		double	y,
		const std::string &	text
	)			[virtual]

Implements OBPainter.

Referenced by CairoPainter::NewCanvas().

OBFontMetrics GetFontMetrics

(

const std::string &

text

)

[virtual]

Implements OBPainter.
