The CanvasRenderingContext2D
.strokeText()
method of the Canvas 2D API strokes — that is, draws the outlines of — the characters of a specified text string at the given (x, y) position. If the optional fourth parameter for a maximum width is provided, the text is scaled to fit that width.
See the CanvasRenderingContext2D.fillText()
method to draw the text with the characters filled with color rather than having just their outlines drawn.
Syntax
void ctx.strokeText(text, x, y [, maxWidth]);
Parameters
text
- The text to draw using the current
font
,textAlign
,textBaseline
, anddirection
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
Using the strokeText
method
This is just a simple code snippet which uses the strokeText()
method to draw the text.
HTML
<canvas id="canvas"></canvas>
JavaScript
var canvas = document.getElementById('canvas'); var ctx = canvas.getContext('2d'); ctx.font = '48px serif'; ctx.strokeText('Hello world', 50, 100);
