The CanvasRenderingContext2D
.fill()
method of the Canvas 2D API fills the current or given path with the current fillStyle
.
Syntax
void ctx.fill([fillRule]); void ctx.fill(path [, fillRule]);
Parameters
fillRule
- The algorithm by which to determine if a point is inside or outside the filling region.
Possible values:"nonzero"
: The non-zero winding rule. Default rule."evenodd"
: The even-odd winding rule.
path
- A
Path2D
path to fill.
Examples
Filling a rectangle
This example fills a rectangle with the fill()
method.
HTML
<canvas id="canvas"></canvas>
JavaScript
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); ctx.rect(10, 10, 150, 100); ctx.fill();
Result
Specifying a path and a fillRule
This example saves some intersecting lines to a Path2D object. The fill()
method is then used to render the object to the canvas. A hole is left unfilled in the object's center by using the "evenodd"
rule; by default (with the "nonzero"
rule), the hole would also be filled.
HTML
<canvas id="canvas"></canvas>
JavaScript
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); // Create path let region = new Path2D(); region.moveTo(30, 90); region.lineTo(110, 20); region.lineTo(240, 130); region.lineTo(60, 130); region.lineTo(190, 20); region.lineTo(270, 90); region.closePath(); // Fill path ctx.fillStyle = 'green'; ctx.fill(region, 'evenodd');
