Convert NRW to VIPS

The NRW file extension stands for Nikon Raw Image, a proprietary raw image format used by Nikon digital cameras, particularly the high-end COOLPIX models. NRW files store uncompressed, unprocessed image data, allowing for greater post-processing flexibility and higher image quality compared to compressed formats like JPEG. Introduced to support Windows Imaging Component (WIC) functions, NRW files enable photographers to adjust color, brightness, and other image attributes with precision. Compatible with various image editing software, including Nikon ViewNX2 and Adobe Photoshop, NRW files are essential for professional photography.

The VIPS (Virtual Image Processing System) file format, developed by the libvips library, is designed for high-performance image processing with low memory usage. It supports arbitrary metadata and is optimized for command-line operations. Although not widely supported by other programs, it serves as an efficient intermediate format for tasks like image inversion and gamma correction. The format includes a 64-byte header with basic fields such as image width and a set of band-interleaved scanlines for the image data.
