Kubadilisha Ukubwa wa Mistari kwenye Canvas kwa JavaScript

Unene wa mstari umewekwa kwa kutumia sifa lineWidth. Weka tu thamani ya unene, kwa mfano hivi: lineWidth = 5 - utapata unene wa mstari wa 5px. Tuangalie kwa mfano:

html<canvas width="200" height="200" style="background: #f4f4f4;"></canvas>

javascriptlet canvas = document.querySelector('canvas');
let ctx = canvas.getContext('2d');

ctx.beginPath();
ctx.lineWidth = 5; // unene 5px
ctx.moveTo(50, 50);
ctx.lineTo(150, 50);
ctx.stroke();

Результат:

Unene unaweza pia kubadilishwa kwa misingi, kwa mfano ile iliyochorwa kwa kutumia rect:

html<canvas width="200" height="200" style="background: #f4f4f4;"></canvas>

javascriptlet canvas = document.querySelector('canvas');
let ctx = canvas.getContext('2d');

ctx.rect(50, 50, 100, 100);
ctx.lineWidth = 5;
ctx.stroke();
