Public Methods

 CanvasImage (const PixelFormat &format=GrayChar)
 CanvasImage (int width, int height, const PixelFormat &format=GrayChar)
 CanvasImage (const Image &that)
void initialize ()
virtual ~CanvasImage ()
virtual void drawPoint (const Point &p, unsigned int color=0xFFFFFF)
virtual void drawSegment (const Point &a, const Point &b, unsigned int color=0xFFFFFF)
virtual void drawLine (float a, float b, float c, unsigned int color=0xFFFFFF)
 Draws the set ax + by + c = 0.

virtual void drawRay (const Point &p, float angle, unsigned int color=0xFFFFFF)
virtual void drawPolygon (const std::vector< Point > &points, unsigned int color=0xFFFFFF)
virtual void drawFilledRectangle (const Point &corner0, const Point &corner1, unsigned int colorFill=0xFFFFFF)
virtual void drawEllipse (const Point &center, const Matrix2x2< double > &shape, float radius=1, unsigned int color=0xFFFFFF, float startAngle=0, float endAngle=2 *PI, bool inverse=false)
 Draws the set ~x * !shape * x == radius^2. shape has same semantics as a covariance matrix. It transforms a circle into an ellipse. radius, startAngle and endAngle are relative to that circle before it is transformed.

virtual void setTranslation (float x, float y)
 Location of origin in this Canvas' coordinate system.

virtual void setScale (float x, float y)
 Multiply all coordinates by a factor. Scaling is done before translation.

virtual void setLineWidth (float width)
 Width of pen for stroking lines, in native units.

virtual void setPointSize (float radius)
 Set distance away from position of point that marker may extend.

Point trans (const Point &p)
void pen (const Point &p, unsigned int color)
