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
https://mail.gnome.org/archives/eog-list/2016-January/msg00004.html[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.
