37 * @brief A helper class for writing to MonoPictureAssets
39 * Objects of this class can only be created with MonoPictureAsset::start_write().
41 * Frames can be written to the MonoPictureAsset by calling write() with a JPEG2000 image
42 * (a verbatim .j2c file). finalize() must be called after the last frame has been written.
43 * The action of finalize() can't be done in MonoPictureAssetWriter's destructor as it may
