此 svg 在浏览器（ffox、chrome、http://jsfiddle.net/9tT6T/)，但当导出为 png 时，inkscape 和 imagemagick 只会将其转换为白色矩形。如何将此 svg 栅格化为 png？

答案1
显然，Inkscape 要求将遮罩包含在组中。在元素<g> ... </g>内部mask，在其其余内容周围添加，它将在 Inkscape 中正确显示和渲染。
ImageMagick 几乎可以在组就位的情况下正确渲染它，但它会破坏透明度（尝试使用彩色背景矩形而不是白色）。GraphicsMagic 似乎完全忽略了遮罩，即使组就位也是如此。
如果您的最终目标是使用 ImageMagick 来渲染这些，我认为您可能只需放弃蒙版并使用-transparent <color>设置convert。
