%LINE  Draws a line segment connecting two points
%
%    img = cv.line(img, pt1, pt2)
%    [...] = cv.line(..., 'OptionName', optionValue, ...)
%
% ## Input
% * __img__ Image.
% * __pt1__ First point of the line segment.
% * __pt2__ First point of the line segment.
%
% ## Output
% * __img__ Output image.
%
% ## Options
% * __Color__ 3-element floating point vector specifying line color.
% * __Thickness__ Line thickness. default 1.
% * __LineType__ Type of the line boundary. One of 8,4,'AA' (Anti-aliased
%        line). default 8.
% * __Shift__ Number of fractional bits in the point coordinates. default 0
%
% The function line draws the line segment between pt1 and pt2 points in
% the image. The line is clipped by the image boundaries. For
% non-antialiased lines with integer coordinates, the 8-connected or
% 4-connected Bresenham algorithm is used. Thick lines are drawn with
% rounding endings. Antialiased lines are drawn using Gaussian filtering.
