class CJPEGExifEncoder : public CImageEncoder;
Provides access to the exif jpeg encoder.
This class provides functions to encode jpeg images held in files or descriptors.
CBase
-
Base class for all classes to be instantiated on the heap.
CImageEncoder
-
Provides access to the ICL (image conversion library) encoders.
CJPEGExifEncoder
-
Provides access to the exif jpeg encoder.
