Code Examples

client

This example creates ansvgelement including a keybind (F2) to add a child rect node, with the use of callbacks to notify in debugscript when the SVG was updated.

-- This could also be a file, with the path provided to svgCreate instead
local rawSvgData = [[
    <svg viewBox="0 0 500 500" xmlns="http://www.w3.org/2000/svg">
        <circle cx="250" cy="250" r="250" fill="#0fc0fc" />
    </svg>

    -- Apply our XML to the SVG, and start drawing via callback
    svgSetDocumentXML(svg, svgXML)
