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.
