有没有办法使用过滤器或 SVG 中的任何方法将图案和渐变一起应用于元素？
我不想创建重复的元素（任何形状）来实现此目的。它是维护开销。
下图是我的预期输出的示例。
<svg xmlns='http://www.w3.org/2000/svg' width='100%' height='100%'>
<defs>
<pattern id='tile' patternUnits='userSpaceOnUse' width='75' height='75' viewBox='0 0 50 50'>
<line x1='1' y1='0' x2='51' y2='50' stroke='#19203d' stroke-width='2'/>
<line x1='49' y1='0' x2='-1' y2='50' stroke='#19203d' stroke-width='2'/>
<line x1='50' y1='0' x2='0' y2='50' stroke='#313763' stroke-width='2'/>
<line x1='0' y1='0' x2='50' y2='50' stroke='#313763' stroke-width='2'/>
</pattern>
<radialGradient id='l' cx='50%' cy='200%' fy='0' r='201%'>
<stop offset='0%' style='stop-color:#fff; stop-opacity:.1;' />
<stop offset='10%' style='stop-color:#000; stop-opacity:0.1;' />
<stop offset='30%' style='stop-color:#000; stop-opacity:0.3;' />
<stop offset='90%' style='stop-color:#000; stop-opacity:0.55;' />
<stop offset='100%' style='stop-color:#000; stop-opacity:.6' />
</radialGradient>
</defs>
<rect fill='#39466b' width='100%' height='100%'/>
<rect fill='url(#tile)' width='100%' height='100%'/>
<rect width='100%' height='100%' fill='url(#l)'/></svg>
我不想重复填充渐变和图案的元素。上面的代码有重复的元素。
虽然这仍然会重复元素，但它在 defs 标记中这样做，这意味着您可以将其应用到一个可见元素。

它使用 rects 作为 feImage 的源，但不幸的是 FireFox 不支持这一点，并且 IE 支持不完整。
这绝不是一个完美的解决方案，但它可能说明了前进的方向。
