I need a svg file with transparent background.
In the following file:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 600.00 400.00" >

<g><image id="SVGimage" x="100" y="100" height="200" width="200" xlink:href="../file.svg"/></g></svg>

So when the svg is applied to a colored canvas I could see the color of the canvas around the image.
I am not certain it is possible.

file.svg
