Embedded png is removed from SVG

[tjandras]

I have an SVG with embedded PNG images in it, like this:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
  <text x="97.5" y="43" fill="rgb(0,0,0)" font-size="24" font-family="monospace" xmlns="http://www.w3.org/2000/svg">Some text</text>
  <text x="97.5" y="67" fill="rgb(0,0,0)" font-size="24" font-family="monospace" xmlns="http://www.w3.org/2000/svg">asd/asd/asd</text>
  <image x="97.5" y="72" width="500" height="500" xlink:href="data: image/png; base64,<data>" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" />
....

But when I open it with Magick.NET and save it again like this: (obviously my real use case include some editing before saving again, but simply saving already "corrupts" the SVG)

var rs = new MagickReadSettings
{
    Format = MagickFormat.Svg
};
using (MagickImage img = new MagickImage("1.svg", rs))
{
    img.Write("my.svg", MagickFormat.Svg);
}

all embedded images disappear. Everything else seems fine. Did I make any mistake, or is it unsupported to have embedded images? Maybe a bug?

I'm using .NET Core on Windows and the latest Magick.NET-Q16-AnyCPU, Version: 7.21.1 Also tried with a bit older version, same thing happens.

Any help is highly appreciated.

Thanks!

PS: I could not attach the SVG file (unsupported file type), but if needed I figure something out.

You can zip this SVG file and then upload it. I suspect that loading embeded images is not supported but I will need to use your test file to make sure.

Thanks for the help!

The problem appears to be that the data should be encoded differently: data:image/png;base64, instead of data:image/png ;base64 ,. Those spaces are not allowed by the code that parses the attribute.

[tjandras]

I see, the sample code above in the original question does have spaces indeed, my bad. But the SVG I attached to your previous comment does not. And that is not working as well.

This is what I see in the SVG file inside the zip.

Yes, you are right, my apologies. I have and created so many svgs that I might mixed some up. This solves the issue. Thank you very much!
