EXTENSIONLIST

typedef struct _tagEXTENSIONLIST 
{ 
   L_UINT uStructSize; 
   L_UINT uFlags; 
   L_UINT uCount; 
   LTEXTENSION aList[1]; 
} EXTENSIONLIST, *pEXTENSIONLIST; 

The EXTENSIONLIST structure contains Exif extension information.

Member Description
uStructSize Size of the whole extension list.
uFlags Flags that indicate the type of data contained in the extensions. Possible values are:
  Value Meaning
  EXTENSION_STAMP [0x0001] A stamp is present. Most likely suitable for LCD displays (and bigger than the stamp stored in the Exif data). The stamp can be loaded with L_LoadExtensionStamp. Note that this stamp is independent of the regular stamp present in Exif files. Some Exif files have two stamps. The regular stamp is loaded with L_ReadFileStamp, while the extension stamp is loaded with L_LoadExtensionStamp.
  EXTENSION_AUDIO [0x0002] Embedded audio data is present. The L_GetExtensionAudio function can be called to get to the audio data.
uCount The number of extensions present in aList.
aList Array of LTEXTENSION structures that contain the extension information. For more information about the information these contain, refer to the LTEXTENSION structure.

Comments
