# how to draw a flower in javascript

const ctx = canvas.getContext("2d"); const petal = [ [ [0, 0], [0.3, -1], [0.7, -1], [1, 0], [0.7, 1], [0.3, 1], [0, 0] ], [ [0, 0], [1, 0] ], ]; function drawPetal(path, width, height) { var i = 0; do { // loop through paths const p = path[i]; let j = 0; ctx.moveTo(p[j][0] * width, p[j++][1] * height); while (j < p.length - 1) { ctx.lineTo(p[j][0] * width, p[j++][1] * height); } if (p[j][0] === p[0][0] && p[j][1] === p[0][1]) { // is the path closed ? ctx.closePath(); } else { ctx.lineTo(p[j][0] * width, p[j][1] * height) } } while (++i < path.length); } function drawPetals(x, y, count, startAt, petal, width, height) { const step = (Math.PI * 2) / count; ctx.setTransform(1, 0, 0, 1, x, y); ctx.rotate(startAt); for (var i = 0; i < count; i += 1) { drawPetal(petal, width, height); ctx.rotate(step); } ctx.setTransform(1, 0, 0, 1, 0, 0); // restore default } function drawFlower(col, lineWidth, fitScale, petalCount) { ctx.strokeStyle = col; ctx.lineWidth = lineWidth; const size = Math.min(ctx.canvas.width, ctx.canvas.height) * fitScale * 0.5; ctx.beginPath(); drawPetals(ctx.canvas.width / 2, ctx.canvas.height / 2, 5, -Math.PI / 2, petal, size, size * 0.2); ctx.stroke(); ctx.beginPath(); ctx.arc(ctx.canvas.width / 2, ctx.canvas.height / 2, size * 0.15, 0, Math.PI * 2); ctx.fillStyle = col; ctx.fill(); } drawFlower("black", 4, 0.95, 5);

**Here is what the above code is Doing:**

1. We create a canvas element and a 2D context.

2. We define a petal shape as a list of paths.

3. We define a function to draw a petal shape.

4. We define a function to draw a flower.

5. We draw a flower.

The petal shape is defined as a list of paths. Each path is a list of points.

The drawPetal function takes a path and draws it.

The drawPetals function takes a position, a count, a start angle, a petal shape, a width and a height. It draws the petal shape count times, rotating it by step degrees each time.

The drawFlower function takes a color, a line width, a fit scale and a petal count. It draws a flower with the given color, line width, fit scale and petal count.

The last line draws a flower.

The drawPetals function is the most interesting one. It takes a position, a count, a start angle, a petal shape, a width and a height. It draws the petal shape count times, rotating it by step degrees each time.

The drawFlower function takes a color, a line width, a fit scale and a petal count. It draws a flower with the given color, line width, fit scale and petal count.
