使用SVG的条纹椭圆 [英] Striped oval using SVG

问题描述

我已经在CSS中创建了一个边框和条纹椭圆形，我想做一些类似于SVG的东西。我完全不熟悉SVG，我试过使用Raphael。这就是我所见（请参阅这里）：

I have built a bordered and striped oval in CSS, and I would like to do something similar with SVG. I'm completely new to SVG, and I've tried using Raphael. This is as far as I got (see fiddle here):

var paper = Raphael(150, 150, 320, 320);
var oval = paper.rect(0, 0, 100, 50, 25);
oval.attr('fill', 'crimson');
oval.attr('stroke', 'transparent');

如何使用SVG创建条纹，类似于CSS？

How can I do stripes with SVG, in a similar vein to the CSS?

渐变

- [ - [：]] * - ，例如：
90-＃fff-＃000 - 从白色到黑色的90°渐变或
0-＃fff-＃f00：20-＃000 0°渐变从白色通过红色（在20％）到
黑色。

Gradients

"‹angle›-‹colour›[-‹colour›[:‹offset›]]*-‹colour›", example: "90-#fff-#000" – 90° gradient from white to black or "0-#fff-#f00:20-#000" – 0° gradient from white via red (at 20%) to black.

Raphael文档，我们可以创建一个条纹渐变。这可能是有意义的创建一个函数生成条纹梯度字符串为您。

So using the linear gradient format described in the Raphael documentation, we could create a striped gradient. It would probably make sense to create a function that generates the striped gradient string for you.

function gradientString(color1, color2, step) {
    var gradient = '0-' + color1,
        stripe = false,
        i;

    for (i = 0; i < 100; i += step) {
        if (stripe) {
            gradient += '-' + color1 + ':' + i + '-' + color2 + ':' + i;
        } else {
            gradient += '-' + color2 + ':' + i + '-' + color1 + ':' + i;
        }

        stripe = !stripe;
    }

    return gradient;
}

var paper = Raphael(150, 150, 320, 320);
var oval = paper.rect(0, 0, 100, 50, 25);
oval.attr('fill', gradientString('white', 'crimson', 2));
oval.attr('stroke', 'crimson');
