CanvasRenderingContext2D.fillText()

The CanvasRenderingContext2D.fillText() method of the Canvas 2D API fills a given text at the given (x, y) position. If the optional fourth parameter for a maximum width is provided, the text will be scaled to fit that width.

See also the CanvasRenderingContext2D.strokeText() method to draw stroked text.

Syntax

void ctx.fillText(text, x, y [, maxWidth]);

Parameters

text
The text to render using the current font, textAlign, textBaseline, and direction values.
x
The x axis of the coordinate for the text starting point.
y
The y axis of the coordinate for the text starting point.
maxWidth Optional
The maximum width to draw.  If specified, and the string is computed to be wider than this width, the font is adjusted to use a more horizontally condensed font (if one is available or if a reasonably readable one can be synthesized by scaling the current font horizontally) or a smaller font.

Examples

  <input id="reset" type="button" value="Reset" />
</div>
<textarea id="code" class="playable-code">
ctx.font = "48px serif";

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var textarea = document.getElementById("code");
var reset = document.getElementById("reset");
var edit = document.getElementById("edit");
var code = textarea.value;

function drawCanvas() {
  ctx.clearRect(0, 0, canvas.width, canvas.height);
  eval(textarea.value);
}

reset.addEventListener("click", function() {
  textarea.value = code;
