Convert DNG to VIPS

The Digital Negative (DNG) file extension, developed by Adobe Systems and introduced in 2004, is an open, lossless raw image format designed for digital photography. DNG aims to provide a standardized format for raw files, ensuring compatibility across various software and hardware platforms. It is based on the TIFF/EP standard and incorporates extensive metadata, making it suitable for long-term archival purposes. DNG files are widely supported by numerous camera manufacturers and software applications, facilitating efficient storage, sharing, and editing of high-quality images.

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.
