An image viewer and browser utility. Pix is part of the X-Apps project, which aims at producing cross-distribution and cross-desktop software.
As an image browser, browse your hard disk showing you thumbnails of image files. Thumbnails are saved in the same database used by Nautilus so you don't waste disk space. Implements all of the file management functions you'd expect. As an image viewer it'll display just about every image format out there, from BMP to JPG. Optional support for RAW and HDR (high dynamic range) images. Add comments to images. Organize images in catalogs, catalogs in libraries. Search for images on you hard disk and save the result as a catalog. Search criteria remain attached to the catalog so you can update it when you want. Minor image editing and conversion features.
Especially handy is the capability to rename files in a series (normalizing filenames), edit EXIF data, and deduplicate by image (and not just by file hash). Deduplication can recurse directory structures. It's incredibly fast, too. 500,000 images took less than an hour to process (geeqie ran for three days straight and wasn't even finished).
In the AUR.
