Convert XCF to RAD

The XCF (eXperimental Computing Facility) file extension is the native image format of the GIMP image-editing program. It stores comprehensive image data, including layers, channels, transparency, paths, and guides, facilitating non-destructive editing. Developed by GIMP, XCF ensures all editing information is preserved, allowing users to revert to any editing stage. While primarily used within GIMP, some other programs also support XCF files.

The RAD file extension, associated with the Radiance software suite, stands for Radiance Scene Description. It is used to describe materials and geometry for lighting simulations and rendering programs. Developed by Greg Ward at Lawrence Berkeley National Laboratory, Radiance employs ray tracing and an octree data structure for accurate lighting calculations. RAD files are ASCII text files that must be compiled into an octree before rendering.
