Convert CUBE to JBIG

A CUBE file (short for Color Lookup Utility Table) is a 3D Lookup Table used in Luminar software for color grading and photo editing. It allows photographers to remap colors and adjust tones efficiently. Introduced in Luminar 2018, CUBE files enable users to apply complex color adjustments with a single click, enhancing workflow and creative flexibility. The format is also compatible with other editing software like DaVinci Resolve.

The JBIG (Joint Bi-level Image Group) file extension, standardized as ISO/IEC 11544 and ITU-T T.82 in 1993, is a lossless image compression format primarily used for binary images, such as those in fax transmissions. Developed by the Joint Bi-level Image Experts Group, JBIG offers significant compression efficiency over previous standards, achieving up to 50% better compression than Fax Group 4. Its history dates back to 1988 when ISO and CCITT collaborated to create a unified standard for bi-level image coding.
