Convert CUBE to SR

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 Sun Raster (SR) file extension, is a raster graphics file format developed by Sun Microsystems for use on their SunOS operating system. This format, which stores black-and-white, grayscale, and color bitmapped data, was widely used in UNIX-based systems and supported by various imaging applications. The Sun Raster format includes a header, an optional color map, and the bitmapped image data. Although it does not support transparency, it remains a simple and widely distributed bitmap format.
