XC to OTB conversion is the process of transforming image files in the XC format into the OTB format so they can be opened, edited, or published by software that requires OTB. This conversion remaps XC's image data, metadata, and any supported compression into OTB's container and encoding while aiming to preserve visual fidelity and metadata.
