Hi ROOTers,

looking to the documentation of TPad I found several coordinate systems:

1) X/Y 	  			see functions XtoPixel, YtoPixel
2) U/V     			see functions UtoPixel, VtoPixel
3) Pixel   			see functions XtoPixel, UtoPixel 
4) AbsPixel			see functions XtoAbsPixel, UtoAbsPixel
5) Pad				see functions XtoPad, YtoPad
6) CurrentPad World coordinates see functions PaintLine, PaintText
7) NDC coordinates		see functions PaintLineNDC, PaintTextNDC
8) px/py			see function  ResizePad
9) pad axis coordinates		see function  GetRangeAxis


Is there any description of all these coordinate systems?

Cheers Reiner.
