GetFontName Method (GdPicturePDF)

In This Topic

Returns the name of the font used in the currently loaded PDF document according to the font index you have specified. You can use the GetFontCount method to determine the number of all used fonts in the PDF document. The font index is simply an integer value from 1 to GetFontCount.

This name of the font can be used to find the font's definition in the consumer application or its environment. It is also the name that is used when printing to a PostScript output device.

'Declaration
 
Public Function GetFontName( _
   ByVal FontIdx As Integer _
) As String

public string GetFontName( 
   int FontIdx
)

public function GetFontName( 
    FontIdx: Integer
): String;

public function GetFontName( 
   FontIdx : int
) : String;

public: string* GetFontName( 
   int FontIdx
)

public:
String^ GetFontName( 
   int FontIdx
)

Parameters

FontIdx: The font index. It must be a value from 1 to GetFontCount.

Return Value

The font name (the PostScript name of the font). The GetStat method can be subsequently used to determine if this method has been successful.

Remarks

This method is only allowed for use with non-encrypted documents.

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.
