HTLM5 + CANVA + Javascript

Hi, I already have a little JS script which transform a text (here a Chinese text) into an image : ------------------------------------------------------------------------------------------------------------------------- <style>@font-face { font-family: 'CDuChinois'; src: url('./[login to view URL]');}</style> <canvas id=k1 height=100px width=300px>戴维</canva> <canvas id=k2 height=100px width=300px>达维德</canva> <canvas id=k3 height=100px width=300px>大维大维</canva> ... <script> function drawCanvas() { for (i=0;i!=3;i++) { var canvas = [login to view URL]("k"+i); var context = [login to view URL]('2d'); context.fillStyle="#4d4d4d"; context.font="100px CDuChinois"; [login to view URL]([login to view URL]("k"+i).innerHTML, 0, 85); [login to view URL] = "center"; } } drawCanvas(); </script> ------------------------------------------------------------------------------------------------------------------------- WHAT I WANT : I want it modified to display vertical text on image BUT NOT BY A SIMPLE ROTATION : every single character should not be upside down or on its side.
