Hi,
We need help with text on SVG node.
When we export svg from diagram with text and past this svg to another diagram then svg image incorrect small. If this svg without text - it works OK.
Left part of screenshot with text, right is exactly same but without text.

If your text is transparent ShapeNode, check if its Bounds value isn't larger than the geometric nodes. Node coordinates might be what determines exported SVG viewbox size, and not the actual text placement.

Do you call DrawStyledText from a custom node's Draw override, or e.g. from event handlers such as diagram.DrawForeground?

Besides it when we make SVG from text and make SVG from this text-SVG -> We get filled text.

To draw text I use this code and it works OK, but when I export SVG by MindFusion.Diagramming.Wpf.Export.SvgExporter - I get file path1.svg (in new build it is not working too). If I export this svg with text again I get path2.svg with filled characters (next message):

public override void Draw(DrawingContext graphics, RenderOptions options)
    {
        if (!ShouldRender())
        {
            return;
        }

        var bounds = GetBounds();
        var center = bounds.Location.ToVector() - Bounds.TopLeft.ToVector();
        bounds.Location = new Point(center.X, center.Y);
        var textAttributes = DiagramTextUtils.GetTextAttributesFromDomainEntity(TextGeometry.FontStyle);
        var translationResult = translationService.TranslateVariables(TextGeometry);
        attachedObjects = translationResult.AttachedObjects;
        var coloredText = DiagramTextUtils.ColorizeText(translationResult.TranslatedText, TextGeometry.FontStyle.FontColor);
        ParentDiagram.DrawStyledText(graphics, coloredText, textAttributes, bounds);
    }
 

This is what we can test without having your TextGeometry / attachedObjects definitions:

// TextNode.cs
public override void Draw(DrawingContext graphics, MindFusion.Diagramming.Wpf.RenderOptions options)
{
	var bounds = GetBounds();
	var center = new Vector(bounds.Location.X, bounds.Location.Y) - new Vector(Bounds.TopLeft.X, Bounds.TopLeft.Y);
	bounds.Location = new Point(center.X, center.Y);
	//var textAttributes = DiagramTextUtils.GetTextAttributesFromDomainEntity(TextGeometry.FontStyle);
	//var translationResult = translationService.TranslateVariables(TextGeometry);
	//attachedObjects = translationResult.AttachedObjects;
	//var coloredText = DiagramTextUtils.ColorizeText(translationResult.TranslatedText, TextGeometry.FontStyle.FontColor);
	Parent.DrawStyledText(graphics, Text, this, bounds);
}

...
// Window.cs
void TestSvgExIm()
{
	var node1 = diagram.Factory.CreateShapeNode(
		0, 0, 100, 100, Shapes.Ellipse);
	node1.Brush = Brushes.Transparent;
	var node2 = diagram.Factory.CreateShapeNode(
		0, 100, 100, 100, Shapes.RoundRect);
	node2.Brush = Brushes.Transparent;
	diagram.ResizeToFitItems(0);

	new SvgExporter().Export(diagram, "test1.svg");

	var text = new TextNode();
	text.Bounds = new Rect(10, 30, 50, 20);
	text.Text = "test";
	diagram.Nodes.Add(text);

	new SvgExporter().Export(diagram, "test2.svg");

	var svg1 = new SvgContent();
	svg1.Parse("test1.svg");
	var svgNode1 = diagram.Factory.CreateSvgNode(
		200, 0, 100, 200, svg1);
	svgNode1.Shape = Shapes.Rectangle;
	svgNode1.Transparent = true;

	var svg2 = new SvgContent();
	svg2.Parse("test2.svg");
	var svgNode2 = diagram.Factory.CreateSvgNode(
		330, 0, 100, 200, svg2);
	svgNode2.Shape = Shapes.Rectangle;
	svgNode2.Transparent = true;

	diagram.ResizeToFitItems(50);
} 

and it's showing no difference in SVG bounds. Note that SVG viewport size is set to diagram.Bounds and not to bounding box of just graphics elements, so our best guess is the diagram is larger when you add the TextNode to it.  Either the text node itself is larger than the surrounding graphics nodes from your screenshots (which might not be obvious if only drawing text in its center), or the 'attachedObjects' thing from your Draw method adds some invisible nodes that make the diagram larger.

I think that text in SVG using transform matrix and it could be issue. Can we bake it instantly? But without filling closed characters. Maybe pathes instead of text tag in .svg?
Bounding boxes are correct. But svg content inside incorrect.
It is more reproducible when we start export text not from top-left. After move text to center of diagram size of svg content decreasing.

Right, we have reproduced that now. Our developer will investigate.
