WpfDrawingSettings PixelWidth PixelHeight Have no effect

Currently, we do not transform the DrawingGroup, so this feature only works when creating static images.
You can try rescaling the output of the converter.Read(net.Stream).

I want to make sure if changing the size of DrawingImage can reduce the memory usage?
I tried to change the DrawingGroup directly by modifying the Transform, and the size of the DrawingImage did change, but it didn't seem to decay at all when it was filled into the control. Memory is not reduced.

 var setting = new WpfDrawingSettings() { IncludeRuntime = true, TextAsGeometry = true,EnsureViewboxSize = false};
          
using (FileSvgReader converter = new FileSvgReader(setting))
{
	var drawGroup = converter.Read(net.Stream);
	drawGroup.Transform = new ScaleTransform(0.1, 0.1);
	var draw = new DrawingImage(drawGroup);
	draw.Freeze();
	return draw;
}

I am not sure it will. DrawingImage is basically still a vector drawing implementation of the ImageSource. It is not the actual rendered image, just the source of the image and applying a transformation only add a projection definition.
