Flex中的Spark SVG渲染选项？ [英] Spark SVG renderening options in Flex?
本文介绍了Flex中的Spark SVG渲染选项？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想要做的是在Flex中创建一个工具栏，以便在Illustrator中创建一些矢量图形。
问题是当我将矢量导入Flex作为一个SVG似乎发生了一些缩放（？）似乎发生，像素化我一次清脆的载体。
最初我认为这个问题是因为我的图形很小（32×32）所以我试图直接编码到我的Flex mxml文件，它看起来不错。以下是我正在使用：

使用Flex 4.6.0的方法。
谢谢！
$我注意到，你的SVG文件在SVG节点中指定了硬编码的高度和宽度本身：
... width =32.469pxheight =33.625pxviewBox =0 0 32.469 33.625.. 。
但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将矢量绘制精确地栅格化为33.625px，然后< s：Image /> 在显示列表中大小略有不同，把它作为一个位图来缩放，这种方式无法实现矢量图形的全部目的。
如果你放弃这些大小的属性，它会变得更好吗？
I am a bit new to vectors so bear with me. What I am trying to do is make a toolbar in Flex from some vector graphics I have created in Illustrator.
The problem is when I import the vectors into Flex as an SVG some scaling(?) seems to occur, pixelating my once crisp vector.
Initially I thought the problem was because my graphics were small (32 x 32) so I tried hard coding one directly into my Flex mxml file and it looks great. Here's a comparison :
Obviously hardcoding in not a great solution, besides which I had intended to have the vectors within Spark images because I need tooltip functionality.
This is the SVG file I am using :

Using Flex 4.6.0 by the way.

I notice that your SVG file specifies hard-coded height and width in the SVG node itself:
... width="32.469px" height="33.625px" viewBox="0 0 32.469 33.625" ...
but in your "hard-coded" version, that node obviously isn't there. Could that be the difference? If Flex rasterizes the vector drawing to be exactly 33.625px high, and then the <s:Image/> is a slightly different size in the display list, it might try to scale it as a bitmap, which sort of defeats the whole purpose of vector graphics.
Does it get better if you just drop those size attributes?
