Convert PWP to VIPS

The PWP file extension stands for PhotoWorks Image File, associated with the PhotoWorks software developed by Seattle FilmWorks. Primarily used in the late 1990s and early 2000s for storing color images, PWP files are similar to SFW files and were commonly used for image downloads from the internet. Although the software is now discontinued, PWP files can be converted to standard JPG images using specific converters.

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.
