The CanvasRenderingContext2D
method lineTo()
, part of the Canvas 2D API, adds a straight line to the current sub-path by connecting the sub-path's last point to the specified (x, y)
coordinates.
Like other methods that modify the current path, this method does not directly render anything. To draw the path onto a canvas, you can use the fill()
or stroke()
methods.
Syntax
ctx.lineTo(x, y);
Parameters
x
- The x-axis coordinate of the line's end point.
y
- The y-axis coordinate of the line's end point.
Return value
Examples
Drawing a straight line
This example draws a straight line using the lineTo()
method.
HTML
<canvas id="canvas"></canvas>
JavaScript
The line begins at (30, 50) and ends at (150, 100).
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); ctx.beginPath(); // Start a new path ctx.moveTo(30, 50); // Move the pen to (30, 50) ctx.lineTo(150, 100); // Draw a line to (150, 100) ctx.stroke(); // Render the path
Result
Drawing connected lines
Each call of lineTo()
(and similar methods) automatically adds to the current sub-path, which means that all the lines will all be stroked or filled together. This example draws a letter 'M' with a single contiguous line.
HTML
<canvas id="canvas"></canvas>
JavaScript
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); ctx.moveTo(90, 130); ctx.lineTo(95, 25); ctx.lineTo(150, 80); ctx.lineTo(205, 25); ctx.lineTo(210, 130); ctx.lineWidth = 15; ctx.stroke();
