Typedef Documentation

typedef ball<grid::square, def::coord> mln::win::disk2d

2D disk window; precisely, ball-shaped window defined on the 2D square grid.

typedef line<grid::square, 1, def::coord> mln::win::hline2d

Horizontal line window defined on the 2D square grid.

An hline2d is centered and symmetric; so its height is 1 and its width (length) is odd.

For instance:

        o o x o o
       

is defined with length = 5.

typedef line<grid::square, 0, def::coord> mln::win::vline2d

Vertical line window defined on the 2D square grid.

An vline2d is centered and symmetric; so its width is 1 and its height (length) is odd.

For instance:

        o
        x
        o
       

is defined with length = 3.

typedef window<mln::dpoint2d> mln::window2d

Type alias for a window with arbitrary shape, defined on the 2D square grid with integer coordinates.
