HTML | canvas arc() Method
The arc() method is used to create an arc/curve i.e. circles, or parts of circles.
Syntax:
context.arc(x, y, r, sAngle, eAngle, counterclockwise);
Parameters:
- x: This parameter specifies the x-coordinate of the center of the circle.
- y: This parameter specifies the y-coordinate of the center of the circle.
- r: This parameter specifies the radius of the circle.
- sAngle: This parameter specifies the starting angle, in radians( 3 o’clock position of the arc’s circle denotes 0).
- eAngle: This parameter specifies the ending angle in radians.
- counterclockwise: This parameter specifies the drawing should be clockwise or anticlockwise. It is false by default which denotes clockwise.
Example 1:
<!DOCTYPE html><html> <head> <title> HTML canvas arc() Method </title></head> <body style="text-align:left;"> <h1>GeeksforGeeks</h1> <h2>HTML canvas arc() Method</h2> <canvas id="GFG" width="500" height="200"> </canvas> <script> var doc_id = document.getElementById("GFG"); var context = doc_id.getContext("2d"); context.beginPath(); context.strokeStyle = 'green'; context.arc(100, 50, 40, 0, 2 * Math.PI); context.stroke(); </script></body> </html> |
Output:
