GetFontCount Method (GdPicturePDF)
Returns the number of fonts used in the currently loaded PDF document.
A font for use with a PDF consumer application is prepared in the form of a program. Such a font program is written in a special-purpose language, that is understood by a specialized font interpreter.
public int GetFontCount()
public function GetFontCount(): Integer;
public function GetFontCount() : int;
public: int GetFontCount();

'Declaration
Public Function GetFontCount() As Integer
Return Value
The number of fonts used in the document. The
GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.
How to find out the number of all fonts and their properties used in the PDF document.
