Canvas soat: siferblat
II qism - Soat siferblatini chizish
Soatga siferblat kerak. Siferblatni chizish uchun JavaScript funksiyasini yarating:
JavaScript:
function drawClock() {
drawFace(ctx, radius);
}
function drawFace(ctx, radius) {
const grad = ctx.createRadialGradient(0, 0 ,radius * 0.95, 0, 0, radius * 1.05);
grad.addColorStop(0, '#333');
grad.addColorStop(0.5, 'white');
grad.addColorStop(1, '#333');
ctx.beginPath();
ctx.arc(0, 0, radius, 0, 2 * Math.PI);
ctx.fillStyle = 'white';
ctx.fill();
ctx.strokeStyle = grad;
ctx.lineWidth = radius*0.1;
ctx.stroke();
ctx.beginPath();
ctx.arc(0, 0, radius * 0.1, 0, 2 * Math.PI);
ctx.fillStyle = '#333';
ctx.fill();
}

Kod izohi
Soat siferblatini chizish uchun drawFace() funksiyasini yarating:
function drawClock() {
drawFace(ctx, radius);
}
function drawFace(ctx, radius) {
}
Oq doirani chizing:
ctx.beginPath();
ctx.arc(0, 0, radius, 0, 2 * Math.PI);
ctx.fillStyle = 'white';
ctx.fill();
Radial gradient yarating (asl soat radiusining 95% va 105% i):
grad = ctx.createRadialGradient(0, 0, radius * 0.95, 0, 0, radius * 1.05);
Yoyning ichki, o‘rta va tashqi chetlariga mos keladigan 3 ta rang to‘xtash nuqtasini yarating:
grad.addColorStop(0, '#333');
grad.addColorStop(0.5, 'white');
grad.addColorStop(1, '#333');
Rang to‘xtash nuqtalari 3D effekt hosil qiladi.
Gradientni chizish obyektining kontur uslubi (stroke style) sifatida belgilang:
ctx.strokeStyle = grad;
Chizish obyektining chiziq qalinligini belgilang (radiusning 10% i):
ctx.lineWidth = radius * 0.1;
Aylanani chizing:
ctx.stroke();
Soat markazini chizing:
ctx.beginPath();
ctx.arc(0, 0, radius * 0.1, 0, 2 * Math.PI);
ctx.fillStyle = '#333';
ctx.fill();
