## 8.2. Font families and font styles

All graph objects that uses text allows you to specify the font to be used by calling a `SetFont()` method and specifying three parameters.

1. The font family. This could for example be "Arial", "Times roman" for TTF fonts or "Bitmap font medium size" when using bit-mapped fonts. The font family is specified by using a symbolic constant that starts with the prefix "`FF_`" (for Font Family). A list of all supported font families are shown in Table 8.2.

2. The font style. This specifies if the font should be emphasized as italic, bold, or bold-italic. By default all fonts are rendered with the "normal" style. The fonts style is specified with a symbolic constant that starts with the prefix "`FS_`" (for Font Style). The supported font styles are:

   Table 8.1. Supported Font Styles

   Font style specifier | Description
   --- | ---
   FS_NORMAL | Normal font style
   FS_BOLD | Bold font style
   FS_ITALIC | Italic font style
   FS_BOLDITALIC | Bold + Italic style for font families that support this

   Please note that not all font families support all available styles.

3. The font size. This is specified as an integer and depicts the size of the font given in typographic points (pt).
