UPDATE:
I dont get it. I copy another image/icon and it is broken too, but the base64 code has no "=" jsfiddle.net/TYb59 Is the flatIcon.com page so buggy?

更新：
我不明白。我复制了另一个图像/图标，它也坏了，但是 base64 代码没有“=” jsfiddle.net/TYb59 flatIcon.com 页面有问题吗？

Can I fix this images/icons?

我可以修复这个图像/图标吗？

回答by Guffa

The base64 code that you have copied is broken. Close to the end there is ==in the middle of the code. That is a filler that is placed at the end of a base64 code.

您复制的 base64 代码已损坏。接近尾声的是==代码的中间。那是放置在 base64 代码末尾的填充符。

Remove the part after ==, and it will work fine.

删除之后的部分==，它会正常工作。

Edit:

编辑：

Downloading the svg file from the site and base64 encoding it gives exactly the same result. If there is no signature that you can use to easily fix the code, that is what you would need to do.

从站点下载 svg 文件并对其进行 base64 编码，结果完全相同。如果没有可以用来轻松修复代码的签名，那么这就是您需要做的。

I used C# code like this to base64 encode the image to a text file:

我使用这样的 C# 代码将图像 base64 编码为文本文件：

File.WriteAllText(@"d:\temp\baggage19.txt", Convert.ToBase64String(File.ReadAllBytes(@"d:\temp\baggage19.svg")));

So, after trying a few things (I really needed to display SVG as src="data:"). I came across a couple key points:

所以，在尝试了一些事情之后（我真的需要将 SVG 显示为 src="data:"）。我遇到了几个关键点：

• You don't have to encode it as base64, pure svg can be used, this makes it much more readable, as well as smaller both in length and after gzip. It's also much easier to test/debug/edit.
• It is imperitiveto have the xmlnsattribute in the svgtag regardless of whether you use base64, or utf8. That was the piece that eluded me the most.

• 您不必将其编码为 base64，可以使用纯 svg，这使其更具可读性，并且长度和 gzip 后都更小。测试/调试/编辑也容易得多。
• 这是imperitive有xmlns在属性svg标签不管你是否使用的base64，或UTF8。那是最让我望而却步的作品。

Now without further ado, a simple example:

闲话少说，举个简单的例子：

<img src="data:image/svg+xml;utf8, <svg xmlns='http://www.w3.org/2000/svg'><line x1='0' y1='0' x2='200' y2='200' style='stroke:rgb(255,0,0);stroke-width:2'/></svg>" />

I would recommend downloading the image. Upload it yourself and putting it with the link. Look at my comment above. Not letting me post jsfiddle..

我建议下载图像。自己上传并将其与链接放在一起。看看我上面的评论。不让我发布 jsfiddle ..
