nana::paint::image_process::line_interface Description The interface of line algorithm. Model of None Public base classes None Members virtual ~line_interface() = 0; The destruction interface virtual void process(nana::paint::pixel_buffer & pixbuf, const nana::point& pos_beg, const nana::point& pos_end, nana::color_t color, double fade_rate) const = 0; Draws a line, the range of line is [pos_beg, pos_end]. If fade_rate is not 0, the line is blended to the pixbuf, value of fade_rate is in the range of [0, 1]. File nana/paint/image_process_interface.hpp Notes 1, The two points are calculated by Nana, they are always valid, and pos_beg.x <= pos_end.x 2, The semantics of the algorithm is:    Draws line [pos_beg, pos_end]    pixbuf = pixbuf * (1 - fade_rate) + color * fade_rate See also None.
