TextMesh Pro Get size of a text that overflows

Hello,

I'm working of a project where I need to make an automatic horizontal scrolling text. To do that, i thought that the easiest way was to use a mask and to change the x position of my component back and forth using a Tween. But in order to do that, i need to get the size of the component that overflows, is there any way to get this ?

By searching, i only found this kind of methods :

Code (CSharp):

1. GUI.skin.label.CalcSize

Unfortunately this isn't precise and I would need the size of the entire text with the settings of the text (font size, margins, etc).

Also an extra question, is there a way to know if a text is overflowing or not in a script ?

Thank you,
Corentin PB
