The FONTMETRIC() function returns the attributes of a font installed in the Microsoft Windows environment. Font attributes include the character height, character ascent, leading space between lines, and font weight. The syntax of the FONTMETRIC() function is as follows: 

   FONTMETRIC(<expN1>[,<expC1>,<expN2>[,<expC2>]])
The <expN1> parameter specifies the desired font attribute. If the <expC1> and <expN2> parameters are omitted, FONTMETRIC() returns the specified attribute of the current font in the active output window. The following table lists the <expN1> values and their corresponding font attributes. 

   <expN1> value   Attribute
   --------------------------------------------------------------------

    1              Character height in pixels
    2              Character ascent (units above baseline) in pixels
    3              Character descent (units below baseline) in pixels
    4              Leading (space between lines) in pixels
    5              Extra leading in pixels
    6              Average character width in pixels
    7              Maximum character width in pixels
    8              Font weight
    9              Italic (zero = no, nonzero = yes)
   10              Underlined (zero = no, nonzero = yes)
   11              Strikeout (zero = no, nonzero = yes)
   12              First character defined in font
   13              Last character defined in font
   14              Default character (substituted for
                      characters not in font)
   15              Word break character
   16              Pitch and family
   17              Character set
   18              Overhang (extra added width)
   19              Horizontal aspect for font device
   20              Vertical aspect for font device
The <expC1> parameter specifies a font name and returns the desired attribute for a specific installed font.

The <expN2> parameter specifies the point size for a font specified in the <expC1> parameter.

The <expC2> parameter specifies a font style code. When an application specifies <expC2>, FoxPro returns the desired attribute for a font with the specified font style. If <expC2> is omitted, FoxPro returns the specified information regarding a font with normal style. The <expC2> parameter can contain one or more characters from the following font style table. 

   Character       Font style
   ---------------------------

       -           Strikeout
       B           Bold
       I           Italic
       N           Normal
       O           Outline
       Q           Opaque
       S           Shadow
       T           Transparent
       U           Underline
