Hello everybody,  
There is a way to set the display node glyph size as a physical length programmatically like pressing the button “absolue” in the Display Menu of Markups Module (see the attach)?  
When I set the size using for example :  
myDisplayNode.SetGlyphSize(1.7)  
I feel like the glyph size remains relative …  
Thanks!  
Sara

Using `SetUseGlyphScale(False)` on the display node is what you are looking for. Then `SetGlyphSize(sizeMm)` to set the glyph size in mm.
