Accessing tree structure of Document

[Jelim16]

Hello, first of all I would like to thank you for this amazing library. I managed to build it with Visual Studio 2022 and use within MFC executable. Now I am trying to render some SVG sprites file into bitmap in order to load it into CImageList. Is it possible to somehow access tree structure of lunasvg::Document to find out how many sprites are inside?

Example of SVG with 3 separate sprites, each one to be loaded as single image in CImageList:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="300" height="100">
    <svg id="circle" width="100" height="100">
      <circle cx="50" cy="50" r="40" stroke="black" stroke-width="1" fill="red" />
    </svg> 

    <svg id="square" width="100" height="100" transform="translate(100,0)">
      <rect width="80" height="80" x="10" y="10" style="fill:rgb(0,0,255);stroke-width:1;stroke:rgb(0,0,0)" />
    </svg>

    <svg id="triangle" width="100" height="100" transform="translate(200,0)">
      <polygon points="50,10 10,90 90,90" style="fill:lime;stroke:purple;stroke-width:1" />
    </svg>
</svg>

No... Because DOM Tree is destroyed after loading and the Layout Tree is private. But since SVG is the same XML, you can use any XML library to do the job.

FYI I am currently working on a way to render individual element.

Example :

Bitmap Document::renderElement(std::string& id); // Renders an Element by ID onto the bitmap

Bitmap bitmap = document->renderElement("triangle"); // Renders an Element by the ID triangle onto the bitmap.

OK, thank you.
