我正在尝试将带有nodejs的图像base64'ed以原始格式保存到ODT文件中，以便在OpenOffice Writer中显示。
规格不是很清楚，但我找到了一个例子。但是，当我发布以下base64'd图像(在html中看起来不错)时，我在OpenOffice中出现"读取错误"并且图像不显示。
该规范说它使用 rfc2045，但该规范不是很具体(除非我错过了什么)。
这是我所拥有的：

我可以使用 base64 转换库，例如这个 nodejs 转换库。预期什么格式？
好吧，伙计们的答案如下：

也就是说，
- 编码不能以
data:image/png;base64,为前缀 <draw:image>元素不能具有xlink:href="Pictures/0.png"属性。即使规范说如果存在<office:binary-data>它将被忽略。耸肩。
