(image) text


  
  
  
  
  
  # In Contact 4.3 there is the new option of creating a 
  # textured rectangle for each character. The
  # user first must supply a special Font texture in a 
  # ImageTexture node and sets the fontstyle
  # family attribute to "TEXTURE".
  #
  # The Text attributes length and maxExtent, the FontStyle 
  # attributes size, spacing, leftToRight, topToBottom, justify 
  # and style = PLANE or ITALIC are implemented for TEXTURE text. 
  # The square texture map is divided into 16*16 cells for 256 different 
  # characters, the character 0 start in the upper left corner 
  # of the pixel image. The character width is scaled by 0.8. The
  # Appearance node or Texture node should be reused between 
  # different text strings for speed.
  #
  # For special effects or fonts the texture map can be tuned. 
  # Using textures with alpha (or a transparent GIF) can give a 
  # transparent background. Using grayscale or black & white textures
  # allows color changes using the Material diffuseColor.
  #
  # To further optimize the Text texture resolution and layout 
  # custom layout settings can be specified with up to 7 numbers 
  # after the family "TEXTURE" string. The format is "TEXTURE
  # minChar maxChar cols rows aspect extraSpace shift"
