30 /** @class StereoPictureAssetWriter
31 * @brief A helper class for writing to StereoPictureAssets.
33 * Objects of this class can only be created with StereoPictureAsset::start_write().
35 * Frames can be written to the StereoPictureAsset by calling write() with a JPEG2000 image
36 * (a verbatim .j2c file). finalize() must be called after the last frame has been written.
37 * The action of finalize() can't be done in StereoPictureAssetWriter's destructor as it may
