1.4.4 Font style

Text style is specified by the string which may contain several characters of font (‘ribwou’) and/or align (‘LRC’) specifications. The string also may contain the color id characters ‘wkrgbcymhRGBCYMHW’ (see section mglColor class) after the symbol ‘:’. For example, ‘biC:b’ sets the bold italic font text aligned at the center and with blue color.

The font types are: ‘r’ – roman font, ‘i’ – italic style, ‘b’ – bold style. By default roman roman font is used. The align types are: ‘L’ – align left (default), ‘C’ – align center, ‘R’ – align right. Additional font effects are: ‘w’ – wired, ‘o’ – over-lined, ‘u’ – underlined. Also a parsing of the LaTeX-like syntax is provided (for detail, see section mglFont class and Font settings).

The font size can be defined explicitly (if size>0) or relatively the base font size as |size|*FontSize (if size<0). The value size=0 specifies that the string will not be printed. The base font size is measured in internal “MathGL” units. Special functions SetFontSizePT(), SetFontSizeCM(), SetFontSizeIN() allow one to set it in more “common” variables for given dpi of the picture.
