Detailed Description

A helper class for writing to MonoJ2KPictureAssets.

Objects of this class can only be created with MonoJ2KPictureAsset::start_write().

Frames can be written to the MonoJ2KPictureAsset by calling write() with a JPEG2000 image (a verbatim .j2c file). finalize() should be called after the last frame has been written, but if it is not, it will be called by the destructor (though in that case any error during finalization will be ignored).
