lineCap property
The lineCap property sets the
type of a line end. Can take the
following values: butt - flat
end (default), round - rounded
end, square - square end.
Syntax
context.lineCap = 'butt', 'round' or 'square';
Example
Let's draw some lines and set the first
to butt, the second to round,
and the third to square. Pay
attention to the red line - it marks
the set beginning of the line
(and round and square climb out of it):
<canvas id="canvas" width="200" height="200" style="background: #f4f4f4;"></canvas>
let canvas = document.querySelector('#canvas');
let ctx = canvas.getContext('2d');
ctx.beginPath();
ctx.lineWidth = 10;
ctx.lineCap = 'butt';
ctx.moveTo(75, 50);
ctx.lineTo(75, 150);
ctx.stroke();
ctx.beginPath();
ctx.lineWidth = 10;
ctx.lineCap = 'round';
ctx.moveTo(105, 50);
ctx.lineTo(105, 150);
ctx.stroke();
ctx.beginPath();
ctx.lineWidth = 10;
ctx.lineCap = 'square';
ctx.moveTo(135, 50);
ctx.lineTo(135, 150);
ctx.stroke();
ctx.beginPath();
ctx.lineWidth = 1;
ctx.lineCap = 'butt';
ctx.strokeStyle = 'red';
ctx.moveTo(60, 50);
ctx.lineTo(150, 50);
ctx.stroke();
