Imagick::setFont — Sets font
$font
   )
   Sets object's font property. This method can be used for example to set font for 
   caption: pseudo-format. The font needs to be configured in ImageMagick configuration
   or a file by the name of font must exist. This method should
   not be confused with ImagickDraw::setFont() which sets the font
   for a specific ImagickDraw object.
   This method is available if Imagick has been compiled against ImageMagick version 6.3.7 or newer.
  
fontFont name or a filename
   Returns TRUE on success.
