Occurs when the blob provider encounters an image of an unregistered format.

Delphi syntax:

TTdbBlobProviderUnknownFormatEvent = procedure(Marker: Integer) of object;

property OnUnknownFormat: TTdbBlobProviderUnknownFormatEvent read FOnUnknownFormat write FOnUnknownFormat;

C++ syntax:

typedef void __fastcall (__closure *TTdbBlobProviderUnknownFormatEvent)(int Marker);

__property TTdbBlobProviderUnknownFormatEvent = {read=FOnUnknownFormat, write=FOnUnknownFormat};

Description

Handle this event, if the application wants to handle the case of an unknown image format by itself.
