11 Canvas <canvas> 태그 : JavaScript 를통해그래픽스를그릴때사용 <canvas> 요소는그리는능력은없음 그래픽스를그리기위해서는 JavaScript 를사용 getcontext() method: an object(methods and properties for drawing on the canvas) getcontext("2d") object: text, lines, boxes, circles, and more - on the canvas. 11

12 Canvas 예 <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>canvas 예 </title> <script> function init() { var ctx = document.getelementbyid("canvas").getc ontext("2d"); ctx.strokestyle="rgb(200,0,0)"; ctx.clearrect(0, 0, 400, 300); ctx.strokerect(0, 0, 400, 300); ctx.stroke(); } </script> </head> <body onload="init();"> <canvas id="canvas" width = "400" height="300"> 이브라우져는 HTML5 의 Canvas 요소를지원하지않습니다. </canvas> <br/> </body> </html> 12

15 Canvas 선그리기 moveto(x,y) defines the starting point of the line lineto(x,y) defines the ending point of the line stroke() method to actually draw the line var c = document.getelementbyid("mycanvas"); var ctx = c.getcontext("2d"); ctx.moveto(0,0); ctx.lineto(200,100); ctx.stroke(); 15
