Sets the underlying XML document from an SVG element.

[[{{{image}}}|link=|]] Important Note: Before r21155 (3157905) the provided callback wasn't stored on the SVG and was only fired once after the function had performed its task. This is no longer the case - each SVG can now store a single callback function (optional) which is fired every time the SVG texture has been changed/updated.


bool svgSetSize( svg svgElement, int width, int height [, function callback ( element svg ) ] )

Required Arguments

  • svgElement: The svg element you want to set the size of.
  • width: Desired width, preferably power of two (16, 32, 64 etc.), maximum is 4096
  • height : Desired height, preferably power of two (16, 32, 64 etc.), maximum is 4096

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • callback: A callback function which is stored on the SVG and fired every time the SVG texture is updated (for example, via svgSetDocumentXML). Note: if present, this will overwrite the current callback stored on the svg


  • Returns true if successful, false otherwise


This example creates an svg element including a keybind (F2) to resize the SVG randomly, 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="">
        <circle cx="250" cy="250" r="250" fill="#0fc0fc" />

local svgs = {}

local function render(svg)
    if (not isElement(svg)) or (getElementType(svg) ~= "svg") then
        removeEventHandler("onClientRender", root, svgs[svg].handler)
        svgs[svg] = nil

    local width, height = svgGetSize(svg)
    dxDrawImage(0, 0, width, height, svg, 0, 0, 0, tocolor(255, 255, 255), false)

local function onUpdate(svg)
    -- If this is the first update, add svg to our table and start drawing it
    if (not svgs[svg]) then
        svgs[svg] = {
            state = true,
            handler = function()

        addEventHandler("onClientRender", root, svgs[svg].handler)

    iprint("SVG texture updated", svg, getTickCount())

local function init()
    -- Create an SVG containing a circle, using the raw XML data above
    local mySvg = svgCreate(500, 500, rawSvgData, onUpdate)

    -- Bind a key to set SVG to a random size, which will trigger the onUpdate callback
    bindKey("F2", "down", function()
addEventHandler("onClientResourceStart", resourceRoot, init)

function setRandomSVGSize(svg)
    local width, height = svgGetSize(svg)
    local diff = math.min(width, height) /  math.max(width, height)
    local size = math.random(100, 500)

    svgSetSize(svg, size, size * diff)
