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.
