FontStyle Node

This node is used inside the Text node to specify the display properties of the strings. The following fields are present:
  • family specifies the font family. Values for this field are: "SERIF", "SANS", "TYPEWRITER".
  • style specifies the font style. Values for this field are: "PLAIN", "BOLD", "ITALIC", "BOLDITALIC".
  • horizontal is a boolean field which specifies if the text is to be displayed horizontally. 
  • leftToRight is a boolean field which specifies if the text is displayed left to right or right to left (Arabic way)
  • topToBottom is a boolean field which specifies if the text is displayed top to bottom or bottom to top (Chinese way).
  • justify specifies justification both along the major and the minor direction. If horizontal is TRUE then the major direction is horizontal and the minor direction is vertical, otherwise the major direction is vertical and the minor direction is horizontal. If only one value is specified then it refers to the major direction. The default value for the minor direction is "FIRST". There are four possible values for each justification: "FIRST", "BEGIN" (left justified), "MIDDLE" (centered), and "END" (right justified). "BEGIN" and "FIRST" are equivalent except for the minor direction when horizontal is TRUE (see note bellow).
  • language specifies the character set. "en" for English,"en_US" for US english, "zh" for Chinese, etc... Consult the RFC 1766 for the complete list.
  • size specifies character height in VRML units.
  • spacing specifies the spacing between lines. 


  • Syntax:
    FontStyle { 
    • family "SERIF"
    • horizontal TRUE 
    • justify "BEGIN"
    • language ""
    • leftToRight TRUE 
    • size 1.0
    • spacing 1.0
    • topToBottom TRUE 
    }
    Important: VRML is case-sensitive, be careful.

    Note: When horizontal is TRUE the following difference occurs in the minor direction justification between using "FIRST" and "BEGIN":

    "FIRST": The baseline of the first line is placed at the X axis.

    "BEGIN": If topToBottom is TRUE the top edge of the first line is the placed at the X axis, else the bottom edge of the first line is placed at the X axis.

    Consult the specification for full details on text positioning.
