sxiv: Simple (or small or suckless) X Image Viewer
|
||||
|
||||
sxiv is an alternative to feh and qiv. Its only dependency besides xlib is
|
||||
imlib2. The primary goal for writing sxiv is to create an image viewer, which
|
||||
only has the most basic features required for fast image viewing (the ones I
|
||||
want). It has vi key bindings and works nicely with tiling window managers.
|
||||
Its code base should be kept small and clean to make it easy for you to dig
|
||||
into it and customize it for your needs.

@ -15,14 +15,9 @@ Features
|
|||
* Thumbnail mode: grid of selectable previews of all images
|
||||
* Ability to cache thumbnails for fast re-loading
|
||||
* Basic support for multi-frame images
|
||||
* Load all frames from GIF files and play GIF animations
|
||||
* Display image information in window title
|
||||
|
||||
Additional features, that need to be enabled at compile-time (in *config.h*),
|
||||
because they depend on additional libraries:
|
||||
|
||||
* Load all frames from GIF files and play GIF animations (requires giflib)
|
||||
* Auto-orientate JPEG images according to their EXIF tags (requires libexif)
