   ByVal Bold As Boolean, _
   ByVal Italic As Boolean _
) As String

public string AddFontFromFileU( 
   string FilePath,

)

public function AddFontFromFileU( 
    FilePath: String;
    FontName: String;
    CharSet: FontCharSet;
    Bold: Boolean;
    Italic: Boolean
): String;

public function AddFontFromFileU( 
   FilePath : String,
   FontName : String,
   CharSet : FontCharSet,
   Bold : boolean,
   Italic : boolean
) : String;

public: string* AddFontFromFileU( 
   string* FilePath,
   string* FontName,
   FontCharSet CharSet,
   bool Bold,
   bool Italic
)

public:
String^ AddFontFromFileU( 
   String^ FilePath,
   String^ FontName,
   FontCharSet CharSet,
   bool Bold,
   bool Italic
)

Parameters

FilePath: The file path of the resource font file.
Please note that adding a font, that consists from several resource font files, is currently not supported.
FontName: The name of the required font to add for use in the PDF document.
CharSet: A member of the FontCharSet enumeration. Defines the character encoding system (character set) used by the specified font.
Bold: Set this parameter to true if you want to add the font in the bold style, otherwise set it to false.
Italic: Set this parameter to true if you want to add the font in the italic style, otherwise set it to false.

Return Value

Returns a resource name of the specified font required for the next usage within the PDF document. The GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.

This resource name you can subsequently pass, for example, to the GdPicturePDF.DrawText method, as well as to all methods, which have a font resource name as a parameter.

Remarks

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

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

Example

How to add a font from the specified file to the newly created PDF document. The font resource name is subsequently used to draw some unicode text on the newly created page.
