Member Functions Documentation

ConstructL()

IMPORT_C void ConstructL ( ) [protected]

Initialises an exif decoder.

A leave occurs if the associated ICL plugin could not be instanciated

ExifMetadata()

IMPORT_C MExifMetadata * ExifMetadata ( )

gets the metadata associated to this instance of the decoder

NULL is returned if no metadata was found

NewL()

IMPORT_C CJPEGExifDecoder * NewL ( ) [static]

Constructs a new exif decoder.

A leave occurs if there is insufficient memory available.
