我对向量有点陌生，所以请耐心等待。我想做的是用我在 Illustrator 中创建的一些矢量图形在 Flex 中制作一个工具栏。

问题是当我将矢量作为 SVG 导入 Flex 时，似乎会发生一些缩放（？），像素化我曾经清晰的矢量。

最初我认为问题是因为我的图形很小（32 x 32），所以我尝试将一个直接硬编码到我的 Flex mxml 文件中，它看起来很棒。这是一个比较：

在此处输入图像描述

显然，硬编码不是一个很好的解决方案，除此之外，我还打算在 Spark 图像中包含向量，因为我需要工具提示功能。

这是我正在使用的 SVG 文件：

非常感谢有关如何使其正常工作的任何帮助/指示。

顺便说一下，使用 Flex 4.6.0。

谢谢！

我注意到您的 SVG 文件在 SVG 节点本身中指定了硬编码的高度和宽度：

... width="32.469px" height="33.625px" viewBox="0 0 32.469 33.625" ...

但是在您的“硬编码”版本中，该节点显然不存在。这可能是区别吗？如果 Flex 将矢量图形光栅化为 33.625px 高，然后<s:Image/>在显示列表中的大小略有不同，它可能会尝试将其缩放为位图，这有点违背矢量图形的全部目的。

如果您只是删除这些尺寸属性，它会变得更好吗？
