Dear ROOT team,

I'm confused about all the different coordinate systems of a Pad. Is there a
descriptions about all these coordinate systems and how to convert from one
system into an other?
In the class description of Pad I found these coordinate systems:
-  world coordinate system
-  axis coordinate system
-  Pixel
-  AbsPixel
-  Pad
-  NDC
-  X / Y
-  U / V


In the moment I need a conversion from the world coordinate system to the Pixel
- system.

Thanks Reiner.
