## 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 ) | `[virtual]`

Set the painter's font family.

Implements OBPainter.

void SetFontSize | ( | int | pointSize ) | `[virtual]`

Set the painter's font point size.

Implements OBPainter.

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.

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.

OBFontMetrics GetFontMetrics | ( | const std::string & | text ) | `[virtual]`

Implements OBPainter.

void WriteImage | ( | const std::string & | filename ) |
