Question

Which method should be chosen to apply a predefined variable width profile to a drawn path?

Answer 1

To apply a predefined variable width profile to a drawn path, use the stroke() method with the lineWidth property.

Step-by-step explanation:

To apply a predefined variable width profile to a drawn path, you should use the stroke() method with the lineWidth property. The lineWidth property allows you to set the width of the stroke applied to the path. By changing the value of the lineWidth property, you can apply a variable width profile to the path. For example:

ctx.lineWidth = 2; // default width
ctx.beginPath();
ctx.moveTo(50, 50);
ctx.lineTo(150, 50);
ctx.lineWidth = 5; // variable width
ctx.lineTo(150, 150);
ctx.stroke();

In the above code, the path is initially drawn with a default width of 2 and then the width is changed to 5 for the second line segment.
