Drawing Text on the Canvas
To draw text on a canvas, the most important property and methods are:
- font - defines the font properties for the text
- fillText(text,x,y) - draws "filled" text on the canvas
- strokeText(text,x,y) - draws text on the canvas (no fill)
Using fillText()
Example
Set font to 30px "Arial" and write a filled text on the canvas:
Your browser does not support the HTML5 canvas tag.
var c=document.getElementById("myCanvas2");
var canvOK=1;
try {c.getContext("2d");}
catch (er) {canvOK=0;}
if (canvOK==1)
{
var ctx=c.getContext("2d");
ctx.font="30px Arial";
ctx.fillText("Hello World",10,50);
}
JavaScript:
var canvas = document.getElementById("myCanvas");
var ctx = canvas.getContext("2d");
ctx.font = "30px Arial";
ctx.fillText("Hello World",10,50);Try it Yourself »
Using strokeText()
Example
Set font to 30px "Arial" and write a text, with no fill, on the canvas:
Your browser does not support the HTML5 canvas tag.
var c=document.getElementById("myCanvas1");
var canvOK=1;
try {c.getContext("2d");}
catch (er) {canvOK=0;}
if (canvOK==1)
{
var ctx=c.getContext("2d");
ctx.font="30px Arial";
ctx.strokeText("Hello World",10,50);
}

ctx.textAlign = "center";
ctx.fillText("Hello World", c.width/2, c.height/2);
}
