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 EXTENSION structures that contain the extension information. For more information about the information these contain, refer to the EXTENSION structure.
