[Noeilnoeil17]

Hello everyone, I don't understand why i can't change position of my second svg
It is always starting on top left, i would like add logo in center of qrcode

        SvgDocument doc = new SvgDocument();
        var group = new SvgGroup();
        doc.Children.Add(group);
        SvgDocument qr = SvgDocument.Open("qr.svg");
        qr.Width = 300;
        qr.Height = 300;
        SvgDocument logo = SvgDocument.Open("logoI.svg");
        logo.Width = 50;
        logo.Height = 50;
        logo.X = 125;
        logo.Y = 125;
        group.Children.Add(qr);
        group.Children.Add(logo);
        doc.Write("importtest.svg");

if somehone can help me, thanks a lot

var doc = new SvgDocument();
var group = new SvgGroup();
doc.Children.Add(group);
var qrO = SvgDocument.Open(@"qr.svg");
var qr = (SvgFragment)qrO.DeepCopy<SvgFragment>(); // Optional this time.
qr.Width = 300;
qr.Height = 300;
var logoO = SvgDocument.Open(@"logoI.svg");
var logo = (SvgFragment)logoO.DeepCopy<SvgFragment>();
logo.Width = 50;
logo.Height = 50;
logo.X = 125;
logo.Y = 125;
group.Children.Add(qr);
group.Children.Add(logo);
doc.Write(@"importtest.svg");

SvgDocument has characteristics of root <svg>.
So X, Y properties do not work.
By duplicating SvgFragment from SvgDocument, it can be inner <svg>.

If cost of copying is high, there is also method of increasing one layer.

var logoO = SvgDocument.Open(@"logoI.svg");
//var logo = (SvgFragment)logoO.DeepCopy<SvgFragment>();
var logo = new SvgFragment();
logo.Children.Add(logoO);
logo.Width = 50;
logo.Height = 50;

Third plan.

var logoO = SvgDocument.Open(@"logoI.svg");
//var logo = (SvgFragment)logoO.DeepCopy<SvgFragment>();
var logo = new SvgFragment();
foreach (var element in logoO.Children)
    logo.Children.Add(element);
logo.Width = 50;
logo.Height = 50;
