Convert CRW to RAS

The CRW file extension stands for Canon Raw CIFF Image Format, a raw image file format used by Canon digital cameras. Developed to store uncompressed and unprocessed images, CRW files offer high-quality image data that can be edited with Canon's software or third-party editors like Adobe Photoshop. Introduced by Canon, this format has been largely superseded by newer formats like CR2 and CR3 but remains significant in the history of digital photography for its role in preserving image integrity.

The Sun Raster file extension, also known as RAS, is a bitmap graphics file format developed by Sun Microsystems for use on their SunOS operating system. It supports black-and-white, grayscale, and color images with various pixel depths and includes simple Run-Length Encoding (RLE) compression. The format was widely used in UNIX-based systems and is supported by many imaging applications. The RAS format has largely been superseded by more modern formats but remains relevant for legacy systems and specific use cases.
