Convert CUBE to PAM

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 PAM (Portable Arbitrary Map) file extension is a versatile bitmap format used primarily in UNIX-based systems. It extends the Portable Any Map (PNM) format, supporting 2-dimensional image data storage in a binary format with an ASCII header. Introduced to enhance flexibility and interoperability in image processing, PAM files are utilized for various graphical applications, offering a standardized method for handling diverse image types. This format's history traces back to the need for a more adaptable and comprehensive bitmap solution within the PNM family.
