How to trim a svg image in markdown file

I have a svg file, made by Google Drawings. (The png version is shown below

enter image description here

and the svg code is below

<svg version="1.1" viewBox="0.0 0.0 960.0 720.0" fill="none" stroke="none" stroke-linecap="square" stroke-miterlimit="10" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg"><clipPath id="p.0"><path d="m0 0l960.0 0l0 720.0l-960.0 0l0 -720.0z" clip-rule="nonzero"/></clipPath><g clip-path="url(#p.0)"><path fill="#000000" fill-opacity="0.0" d="m0 0l960.0 0l0 720.0l-960.0 0z" fill-rule="evenodd"/><path fill="#999999" d="m393.1811 309.8189l0 0c0 -37.33795 30.268372 -67.60631 67.60632 -67.60631l0 0c17.930298 0 35.12622 7.1227875 47.80487 19.801437c12.67865 12.678619 19.801392 29.874542 19.801392 47.80487l0 0c0 37.33792 -30.268341 67.60629 -67.60626 67.60629l0 0c-37.33795 0 -67.60632 -30.268372 -67.60632 -67.60629z" fill-rule="evenodd"/><path stroke="#000000" stroke-width="1.0" stroke-linejoin="round" stroke-linecap="butt" d="m393.1811 309.8189l0 0c0 -37.33795 30.268372 -67.60631 67.60632 -67.60631l0 0c17.930298 0 35.12622 7.1227875 47.80487 19.801437c12.67865 12.678619 19.801392 29.874542 19.801392 47.80487l0 0c0 37.33792 -30.268341 67.60629 -67.60626 67.60629l0 0c-37.33795 0 -67.60632 -30.268372 -67.60632 -67.60629z" fill-rule="evenodd"/></g></svg>

My purpose is to insert this svg image into a markdown file my_work.md. As you can see, there are lots of white space in the image, I want to trim them off and only show the useful part. In this example, the useful part is just the grey circle.

I have some general ideas, but don't know to to realise them.

  • Direct method: use some markdown tricks to trim it.
  • Indirect method: load this image in Python and trim it using some Python library, export the trimmed svg-image and use it in md-file.
  • Indirect method: trim it in Google Drawings.

Could you please tell me how to do it? Any method is welcomed. I just need to only show the useful part of the image. Please note that I have many svg-files, and the useful part may not be in the center of the image.

Solution

  • To your example I've added ids in order to be able to talk about your paths.

    Path a and b are identical and they arte large rectangles that cover the whole svg canvas. Path a is not visible since is inside a clipPath and path b is transparent: fill-opacity="0.0"

    Also path c and path d are identical. You may remove one of then and add both the stroke and the fill to the same path. Alternatively you put the path c inside a <defs> and use it twice: once for the fill and once for the stroke if this is what you need.

    In order to remove the white space you may delete path b,get the size of path c and use it for the viewBox attribute: in this case viewBox="391 240 139 139" 

    <svg version="1.1" viewBox="391 240 139 139" stroke-miterlimit="10" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg">
