fastiv

fastiv is a fast image viewer, supporting BMP, PNG, GIF, JPEG, and optionally RAW pictures.

It is meant to be a viable replacement for Eye of GNOME, which is slow, likes to break on huge pictures, and its underlying gdk-pixbuf can only be made to use the broken libopenraw as of now.

Further development

Urgent blockers for the first stable version:

• directory browsing

• implement zoom and scrolling

High priority:

• some level of asynchronous loading and preloading, which becomes a difficult problem with network mounts, confusingly acting as fast devices

• write a replacement for GNOME’s Nautilus in grid mode: read-only, with focus on staggered previews and minimising wasted space

Low priority:

• display 16-bit pictures smoothly, using the 30-bit depth under X.org

• make RAW as fast as it can possibly be

• load everything that resembles a picture, potentially even play video

• port to something less hostile than the current GNOME stack, such as SDL, although it may involve a lot of reimplemented code, or result in reduced functionality

Non-goals:

• fancy UI, focus solely on speed of use

• memory efficiency, though preloading can cause some pressure

Packages

Regular releases are sporadic. git master should be stable enough. You can get a package with the latest development version from Archlinux’s AUR.
