opendocument/odt <office:binary-data> 中的图像使用什么 base64 格式，可能是 base64 与 nodejs？
What base64 format to use for images in opendocument/odt <office:binary-data>, possibly base64ing with nodejs?
我正在尝试将使用 nodejs 进行 base64 处理的图像以原始格式保存到 ODT 文件中，以便在 OpenOffice Writer 中显示。
The spec was not very clear, but I found an example。但是，当我 post 以下 base64 图像（在 html 中看起来不错）时，我在 OpenOffice 中得到一个 "Read-error" 并且图像不显示。
规范说它使用 rfc2045，但是 spec is not very specific（除非我遗漏了什么）。
这是我的资料：
