Convert j2c to rgf

What is the difference between .j2c and .rgf?

Description: The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.; The LEGO Mindstorms EV3 Robot Graphics File (RGF) is a proprietary binary file format used by the LEGO Mindstorms EV3 software to store robot graphic models. It is a vector-based file format that stores information such as the robot's 3D geometry, color and other visual properties, as well as the model's connection points, used for connecting with other LEGO elements.
