ROOT 6.18/05 Reference Guide |
Base class for several text objects.
See TAttText for a list of text attributes or fonts, and also for a discussion on text speed and font quality.
By default, the text is drawn in the pad coordinates system. One can draw in NDC coordinates [0,1] if the function SetNDC is called for a TText object.
