I am facing a challenge where I want to make a canvas line wrap around an image with border radius. The idea is to use the canvas element so that I can control how far the rectangle wraps around the image. For instance, setting the value to 1 would result in a minimal wrap, while setting it to 100 would fully encompass the image with border radius. Below is an example using a circle:
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
function newLine(){
let value = (Math.floor(Math.random() * 100) + 1) * 0.06283185307179587;
ctx.clearRect(0, 0, c.width, c.height);
ctx.lineWidth = 10;
ctx.strokeStyle = '#00FF00';
ctx.beginPath();
ctx.arc(100, 75, 55, 0, value);
ctx.stroke();
}
setInterval(()=>{
newLine()
}, 100)img{
width: 100px;
border-radius: 50px;
position: absolute;
left: 58px;
top: 33px;
}<img src="https://media-exp1.licdn.com/dms/image/C4E0BAQHikN6EXPd23Q/company-logo_200_200/0/1595359131127?e=2159024400&v=beta&t=S5MNjBDjiH433VCWzjPeiopNDhxGwmfcMk4Zf1P_m_s"></img>
<canvas id="myCanvas"></canvas>However, when I reduce the border radius slightly, the line no longer wraps around the image. Is there a solution for this issue?
Here is a code snippet illustrating the problem:
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
function newLine(){
let value = (Math.floor(Math.random() * 100) + 1) * 0.06283185307179587;
ctx.clearRect(0, 0, c.width, c.height);
ctx.lineWidth = 10;
ctx.strokeStyle = '#00FF00';
ctx.beginPath();
ctx.arc(100, 75, 55, 0, value);
ctx.stroke();
}
setInterval(()=>{
newLine()
}, 100)img{
width: 100px;
border-radius: 30px;
position: absolute;
left: 58px;
top: 33px;
}<img src="https://media-exp1.licdn.com/dms/image/C4E0BAQHikN6EXPd23Q/company-logo_200_200/0/1595359131127?e=2159024400&v=beta&t=S5MNjBDjiH433VCWzjPeiopNDhxGwmfcMk4Zf1P_m_s"></img>
<canvas id="myCanvas"></canvas>Is there a way to achieve this effect? Thank you.
