	I mean to put the shape in the middle of the diagram, not the picture in the middle of the diagram, how to achieve it?

	I don't quite understand that create an additional node with allowed coordinates (either ContainerNode or a ShapeNode that will be set as a group master), attach the image node to the former / add is as a container child, and then set imageNode.NodeConstraints.KeepInsideParent - that will let users drag the image node only within its container's boundaries.Do you have sample code?

With some 2nd grade math Code imageNode.Bounds = CenterRect( imageNode.Bounds, diagram.Bounds); Rect CenterRect(Rect inner, Rect outer) { var innerCenter = new Point( (inner.Left + inner.Right) / 2, (inner.Top + inner.Bottom) / 2); var outerCenter = new Point( (outer.Left + outer.Right) / 2, (outer.Top + outer.Bottom) / 2); var delta = outerCenter - innerCenter; inner.Offset(delta); return inner; } Regards, Slavcho

	How to change the diagram with the size of the window, and how to lengthen the cross in the diagram to the length and width of the entire diagram?

	How do I get the size of the imageNode to match the size of the local image that I'm exporting?

	What does the code in the red box do? What does the code in the red box do?We didn't find the ShapeNode allowedRangeNode after the program runs.

	That's the node whose coordinates fence your image node, preventing users to drag the image outside. Remove the allowedRangeNode.Transparent = true assignment and you will see it. Quote: How do I get the size of the imageNode to match the size of the local image that I'm exporting? You can get the size from BitmapSource' Width and Height properties. Regards, Slavcho
