Member Function 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

Return Value: A pointer to the metadata

NewL ( )

IMPORT_C CJPEGExifDecoder *

NewL

(

)

[static]

Reimplemented from CImageDecoder::NewL()

Constructs a new exif decoder.

A leave occurs if there is insufficient memory available.

Return Value: A pointer to the new exif jpeg decoder.
