The font family is the name given to a set of fonts by a font designer. The font family can identify generic names (such as SANSERIF and SERIF) or proprietary names (such as Clarendon or Lucida). The font family may have subfamilies. If so, the subfamily is identified as part of the name (for example, Lucida Blackletter). The font family is specified by an SE_String field. The maximum length of a font family name is 32 characters.
The font style specifies the appearance variation allowed within the font family.
The font size specifies how big the text is to be presented. Size is specified in points. It is assumed that an implementation will provide a rational means of mapping points to the size of text in a presentation. Default size is 11 points. Since this element is specified as a float, the size specified may not be mappable to the sizes available for a particular font family. In that case, the size available that is nearest to the requested size shall be used.
The underline style specifies how text is underlined. The default style is SE_ULSTYL_NONE. If a style is specified that is not recognized by an implementation, SE_ULSTYL_SINGLE shall be used. The width of the line used to implement the underlining shall be appropriate to the font size and font style specified.
