IsFontEmbedded Method (GdPicturePDF)

In This Topic
Returns if the font, used in the currently loaded PDF document, according to the font index you have specified, is embedded. 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.

Font embedding means that a full copy of the entire character set of a font is stored in the PDF. A font program can be embedded in a PDF file as data contained in a PDF stream object (also called a font file). Such font programs are subject to copyright, and the copyright owner may impose conditions under which a font program can be used.

Syntax
'Declaration

 

Public Function IsFontEmbedded( _

   ByVal FontIdx As Integer _

) As Boolean
public bool IsFontEmbedded( 

   int FontIdx

)
public function IsFontEmbedded( 

    FontIdx: Integer

): Boolean; 
public function IsFontEmbedded( 

   FontIdx : int

) : boolean;
public: bool IsFontEmbedded( 

   int FontIdx

) 
public:

bool IsFontEmbedded( 

   int FontIdx

) 

Parameters

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

Return Value

true if a font data (a font file) is embedded in the PDF document, otherwise false. 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.
