55 * @brief A helper class for writing to MonoPictureAssets
57 * Objects of this class can only be created with MonoPictureAsset::start_write().
59 * Frames can be written to the MonoPictureAsset by calling write() with a JPEG2000 image
60 * (a verbatim .j2c file). finalize() should be called after the last frame has been written,
61 * but if it is not, it will be called by the destructor (though in that case any error
62 * during finalization will be ignored).
