*-*-*-*-*-*-*-*-*-*-*-*-*Text Attributes class*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* =====================
*-* Text attributes are:
*-* Text Alignment
*-* Text Color
*-* Text Font
*-* Text Size
*-* Text Angle
*-*
*-* This class is used (in general by secondary inheritance)
*-*
*-* by many other classes (graphics, histograms).
*-* align : Text alignment = 10*HorizontalAlign + VerticalAlign
*-* For Horizontal alignment the following convention applies:
*-* 1=left adjusted, 2=centered, 3=rigth adjusted
*-* For Vertical alignment the following convention applies:
*-* 1=bottom adjusted, 2=centered, 3=top adjusted
*-* For example align = 11 = left adjusted and bottom adjusted
*-* align = 32 = right adjusted and vertically centered
*-* angle : Text angle in degrees
*-* color : Text Color Index
*-* font : Text font code = 10*fontnumber + precision
*-* Font numbers must be between 1 and 14
*-* precision = 0 fast hardware fonts (steps in the size)
*-* precision = 1 scalable and rotatable hardware fonts (see below)
*-* precision = 2 scalable and rotatable hardware fonts
*-* precision = 3 scalable and rotatable hardware fonts. Text size
*-* is given in pixels.
*-* size : Character size expressed in percentage of the current pad height
*-* The textsize in pixels (say charheight) will be:
*-* charheight = textsize*canvas_height if current pad is horizontal.
*-* charheight = textsize*canvas_width if current pad is vertical.
*-* charheight = number of pixels if font precision is greater than 2
*-*
*-* Font quality and speed
*-* ======================
*-* When precision 0 is used, only the original non-scaled system fonts
*-* are used. The fonts have a minimum (4) and maximum (37) size in pixels.
*-* These fonts are fast and are of good quality. Their size varies with
*-* large steps and they cannot be rotated.
*-* Precision 1 and 2 fonts have a different behaviour depending if the
*-* True Type Fonts are used or not. If TTF are used, you always get
*-* very good quality scalable and rotatable fonts. However TTF are slow.
*-* Precision 1 and 2 fonts have a different behaviour for Postscript
*-* in case of TLatex objects. With precision 1, the Postscript text uses
*-* the old convention (see TPostScript) for some special characters
*-* to draw sub and superscripts or greek text.
*-* With precision 2 the "PostScript" special characters are drawn as such.
*-* To draw sub and superscripts it is highly recommended to use TLatex
*-* objects instead.
*-*
*-* How to use True Type Fonts
*-* ==========================
*-* You can activate the TTF by adding (or activating) the following line
*-* in your .rootrc file.
*-* Unix.*.Root.UseTTFonts: true
*-* WinNT for NT
*-* You can check that you indeed use the TTF in your Root session.
*-* When the TTF is active, you get the following message at the start
*-* of a session:
*-* "FreeType Engine v1.x used to render TrueType fonts."
*-* You can also check with the command gEnv->Print().
*-*
*-* List of the currently supported fonts (screen and PostScript)
*-* =============================================================
*-* Font ID X11 Win32 TTF lfItalic lfWeight x 10
*-* 1 : times-medium-i-normal "Times New Roman" 1 4
*-* 2 : times-bold-r-normal "Times New Roman" 0 7
*-* 3 : times-bold-i-normal "Times New Roman" 1 7
*-* 4 : helvetica-medium-r-normal "Arial" 0 4
*-* 5 : helvetica-medium-o-normal "Arial" 1 4
*-* 6 : helvetica-bold-r-normal "Arial" 0 7
*-* 7 : helvetica-bold-o-normal "Arial" 1 7
*-* 8 : courier-medium-r-normal "Courier New" 0 4
*-* 9 : courier-medium-o-normal "Courier New" 1 4
*-* 10 : courier-bold-r-normal "Courier New" 0 7
*-* 11 : courier-bold-o-normal "Courier New" 1 7
*-* 12 : symbol-medium-r-normal "Symbol" 0 6
*-* 13 : times-medium-r-normal "Times New Roman" 0 4
*-* 14 : "Wingdings" 0 4

*-*-*-*-*-*-*-*-*Reset this text attributes to default values*-*-*-*-*-*-*
*-* ============================================
void SaveTextAttributes(ofstream &out, const char *name, Int_t alidef, Float_t angdef, Int_t coldef, Int_t fondef, Float_t sizdef)
Save text attributes as C++ statement(s) on output stream out

*-*-*-*-*-*-*-*-*Invoke the DialogCanvas Text attributes*-*-*-*-*-*-*
*-* =======================================
void SetTextSizePixels(Int_t npixels)
Set the text size in pixels.
If the font precision is greater than 2, the text size is set to npixels,
otherwise the text size is computed as a per cent of the pad size.
