◆ DrawLine() [1/2]

void DrawLine ( View< A > &  canvas,
ptrdiff_t  x1,
ptrdiff_t  y1,
ptrdiff_t  x2,
ptrdiff_t  y2,
const Color &  color,
size_t  width = 1 
)

Draws a line at the image.

Parameters
[out]canvas- a canvas (image where we draw line).
[in]x1- X coordinate of the first point of the line.
[in]y1- Y coordinate of the first point of the line.
[in]x2- X coordinate of the second point of the line.
[in]y2- Y coordinate of the second point of the line.
[in]color- a color of the line.
[in]width- a width of the line. By default it is equal to 1.

◆ DrawLine() [2/2]

void DrawLine ( View< A > &  canvas,
const Point< ptrdiff_t > &  p1,
const Point< ptrdiff_t > &  p2,
const Color &  color,
size_t  width = 1 
)

Draws a line at the image.

Parameters
[out]canvas- a canvas (image where we draw line).
[in]p1- the first point of the line.
[in]p2- the second point of the line.
[in]color- a color of the line.
[in]width- a width of the line. By default it is equal to 1.

◆ DrawRectangle()

void DrawRectangle ( View< A > &  canvas,
const Rectangle< ptrdiff_t > &  rect,
const Color &  color,
size_t  width = 1 
)

Parameters
[out]canvas- a canvas (image where we draw rectangle).
[in]rect- a rectangle.
[in]color- a color of the rectangle frame.
[in]width- a width of the rectangle frame. By default it is equal to 1.

◆ DrawFilledRectangle()

void DrawFilledRectangle ( View< A > &  canvas,
Rectangle< ptrdiff_t >  rect,
const Color &  color 
)

Parameters
[out]canvas- a canvas (image where we draw filled rectangle).
[in]rect- a rectangle to fill.
[in]color- a color of the filled rectangle.

◆ DrawPolygon()

void DrawPolygon ( View< A > &  canvas,
const std::vector< Simd::Point< ptrdiff_t >> &  polygon,
const Color &  color,
size_t  width = 1 
)

Draws a polygon at the image.

Parameters
[out]canvas- a canvas (image where we draw polygon).
[in]polygon- a polygon.
[in]color- a color of the polygon.
[in]width- a width of the polygon. By default it is equal to 1.

◆ DrawFilledPolygon()

void DrawFilledPolygon ( View< A > &  canvas,
const std::vector< Simd::Point< ptrdiff_t >> &  polygon,
const Color &  color 
)

Draws a filled polygon at the image.

Parameters

[in]polygon- a polygon.
[in]color- a color of the polygon frame.

◆ DrawEllipse()

void DrawEllipse ( View< A > &  canvas,
const Point< ptrdiff_t > &  center,
const Point< ptrdiff_t > &  axes,
double  slope,
const Color &  color,
size_t  width = 1 
)

Draws an ellipse at the image.

Parameters

[in]center- a center of the ellipse.
[in]axes- axes of the ellipse.
[in]slope- a slope of the ellipse.
[in]color- a color of the ellipse.
[in]width- a width of the ellipse.

◆ DrawCircle()

void DrawCircle ( View< A > &  canvas,
const Point< ptrdiff_t > &  center,
ptrdiff_t  radius,
const Color &  color,
size_t  width = 1 
)
