In this article I am going to draw line with Bresenham's line algorithm. Find more about Bresenham's line algorithm at http://en.wikipedia.org/wiki/Bresenham's_line_algorithm

### CSS :

#line b { position:absolute; color:rgb(91,111,135); } #line { position:relative; margin:auto; width:400px; height:400px; vertical-align:center; }

### jQuery :

**x1, y1 :**First point coordinates

**x2, y2 :**Second point coordinates

**dx :**Difference in X axis coordinates of two points

**dy :**Difference in Y axis coordinates of two points

**p :**Variable to calculate increments in X and Y coordinates

var x1=10, x2=400, y1=10, y2=400; var dx=x2 - x1, dy=y2 - y1; var p=2*dy - dx, i=dx; while (i > 0) { putpixel(x1, y1); if (p < 0) { x1=x1 + 1; p=p + 2*dy; } else { x1=x1 + 1; y1=y1 + 1; p=p + 2*dy - 2*dx; } i--; } function putpixel(mx, my) { $("#line").append("<b style='left:" + mx + "px;top:" + my + "px'>.</b>"); }
