Commented Unassigned: Trying to convert svg content into pdf [1391]

I am trying to convert SVG content into pdf, svg content has one png base 64 content which is not being visible after converting to pdf.

Please help me sort it out this issue. The svg content is attached. I am using Magick.NET-x64 7.0.0.0.

Comments: It turns out that your SVG file contains an incorrect value for the href of the green 'check sign'. `xlink:href="data: image/png` should be `xlink:href="data:image/png`. The extra space is not allowed by librsvg and it looks like that also is not allowed by the RFC: http://tools.ietf.org/html/rfc2397.
