Question: I need to 'scale' text to fill an antire HTML5 canvas. It appears that the `scale()` method does not affect text. I've seen approximation methods with iterative loops on the `measureText()` method but this doesn't get me exactly what I need. Ideally I'd like to fill both horizontally and vertically without conserving the aspect ratio. Would SVG possibly be able to help with this?

Answer: 
My bad - Scale DOES apply to text. I've come up with a solution:

```
context.font = "20px 'Segoe UI'";
var metrics = context.measureText("Testing!");
var textWidth = metrics.width;

var scalex = (canvas.width / textWidth);
var scaley = (canvas.height / 23);

var ypos = (canvas.height / (scaley * 1.25));

context.scale(scalex, scaley);
context.fillText("Testing!", 0, ypos);

```
Scale does affect text. Try this:

```
var can = document.getElementById('test');
var ctx = can.getContext('2d');

ctx.fillText("test", 10, 10); // not scaled text

ctx.scale(3,3);
ctx.fillText("test", 10, 10); // scaled text

```
