希望在SVG元素上结合CSS填充颜色和SVG模式 [英] Looking to combine CSS fill color and SVG pattern on an SVG element

问题描述

我想使用CSS的awesomeness风格的SVG元素结合2件事情：填充颜色和纹理。我的纹理是使用具有笔画但没有填充的SVG图案创建的。但是，即使模式没有填充，它仍然不允许CSS填充颜色通过笔触可见。

I'd like to use the awesomeness of CSS to style SVG elements in combination of 2 things: fill color and texture. My textures are created using SVG patterns that have a stroke but no fill. But even though the pattern has no fill it still won't allow a CSS fill color to be visible through the strokes.

小提琴的一段：

.texture_diagonal{
  fill: url(#texture_diagonal);
}
.cell_default{
  fill: #cccccc;
}
.cell_selected{
  stroke-width: 2px;
  stroke: #FF0000;
}

<pattern id="texture_diagonal" x="0" y="0" width="25%" height="25%" patternUnits="objectBoundingBox">
    <path d="M 0 0 l 32 32" style="stroke: black; fill: none;"/>
</pattern>

<rect x="98" y="115" 
width="32" height="32"
class="texture_diagonal cell_default cell_selected"
/>

在这个例子中，我展示了如何组合CSS类，的矩形可以具有纹理图案和填充颜色。为每个组合定义一个SVG模式（例如：4个纹理X 3填充颜色x 2个选择/未选择= 24个模式需要！）过于繁琐。所以我的问题：

In the fiddle example, I show how I'd like to combine CSS classes so that the third row of rectangles can have both a 'texture' pattern and a fill color. It would be too tedious to define an SVG pattern for each combination (ex: 4 textures X 3 fill colors x 2 selected/unselected = 24 patterns needed!). So my question:

我可以让模式的行为像透明的PNG吗？ （因此图案的空白部分允许在下面显示填充颜色）？

Can I make the pattern behave like a transparent PNG? (so the empty white portion of the pattern allows the fill color to show beneath)?

在我诉诸Peter的解决方案之前， / p>

My last idea before I resort to Peter's solution:

<defs>
<pattern id="texture_diagonal" x="0" y="0" width="25%" height="25%" patternUnits="objectBoundingBox">
    <path d="M 8 0 l 0 32" style="stroke: black; fill: none;"/>
    <path class="myfill" d="M 0 0 l 0 32 l 32 0 l 0 -32 l -32 0"/>
</pattern>
</defs>

<rect x="20" y="20" width="32" height="32"
    class="texture_diagonal cell_connected"/>
<rect x="59" y="20" width="32" height="32"
    class="texture_diagonal cell_default"/>

有没有办法使用CSS组合的选择器来定位'myfill'路径，当它在不同的上下文（cell_connected和cell_default）？

Is there any way to use CSS combination of selectors to target the 'myfill' path when it's in different contexts (cell_connected versus cell_default)?

推荐答案

你不能做你想要的，因为当你设置填充纹理您覆盖原始填充。

You can't do quite what you want because when you set the fill to the texture you overwrite the original fill. The only way I can see around this is to write two rects on top of each other and only texture the top one.

例如：

<rect x="20" y="115" width="32" height="32"
    style="stroke: black;"
    class="cell_default" />

<rect x="20" y="115" width="32" height="32"
    style="stroke: black;"
    class="texture_vertical" />

这不太理想，但工作正常。

It's not ideal, but it works.
