'Declaration
 
Public Function AddTrueTypeFontFromFileU( _
   ByVal FilePath As String, _
   ByVal FileName As String, _
   ByVal Bold As Boolean, _
   ByVal Italic As Boolean, _
   ByVal EnableSubset As Boolean _
) As String

public string AddTrueTypeFontFromFileU( 
   string FilePath,
   string FileName,
   bool Bold,
   bool Italic,
   bool EnableSubset
)

public function AddTrueTypeFontFromFileU( 
    FilePath: String;
    FileName: String;
    Bold: Boolean;
    Italic: Boolean;
    EnableSubset: Boolean
): String;

public function AddTrueTypeFontFromFileU( 
   FilePath : String,
   FileName : String,
   Bold : boolean,
   Italic : boolean,
   EnableSubset : boolean
) : String;

public: string* AddTrueTypeFontFromFileU( 
   string* FilePath,
   string* FileName,
   bool Bold,
   bool Italic,
   bool EnableSubset
)

public:
String^ AddTrueTypeFontFromFileU( 
   String^ FilePath,
   String^ FileName,
   bool Bold,
   bool Italic,
   bool EnableSubset
)

Parameters

FilePath: The file path of the resource font file.
FileName: The name of the required font to add for use in the PDF document.
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.
EnableSubset: Set this parameter to true if you want to subset the font, otherwise set it to false.
Subsetting a font allows you to keep a file smaller, but note that the font subset is gradually updated with each use of the GdPicturePDF.DrawText method.

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 TrueType 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.
