Function Documentation

ClipResult cohen_sutherland_line_clip_d (  double *  x0, double *  y0, double *  x1, double *  y1, double  xmin_, double  xmax_, double  ymin_, double  ymax_ )

cohen_sutherland_line_clip_d: : x coordinate of first point. : y coordinate of first point. : x coordinate of second point. : y coordinate of second point. : x coordinate of lower left edge of clipping rectangle. : y coordinate of lower left edge of clipping rectangle. : x coordinate of upper right edge of clipping rectangle. : y coordinate of lower left edge of clipping rectangle. cohen_sutherland_line_clip_d() will clip a line from first point (, ) to (, ) so that it fits into the given min/max bounds of the rectange (, ) - (, ). The line input coordinates will be modified if necessary for clipping. Returns: ClipResult. Definition at line 100 of file clip.c.
