| 1 | sxiv: Simple (or small or suckless) X Image Viewer |
| 2 | |
| 3 | sxiv is an alternative to feh and qiv. Its only dependency besides xlib is |
| 4 | imlib2. The primary goal for writing sxiv is to create an image viewer, which |
| 5 | only has the most basic features required for fast image viewing (the ones I |
| 6 | want). It has vi key bindings and works nicely with tiling window managers. |
| 7 | Its code base should be kept small and clean to make it easy for you to dig |
| 8 | into it and customize it for your needs. |

| 10 | Features |
| 11 | -------- |
| 12 | |
| 13 | * Basic image operations, e.g. zooming, panning, rotating |
| 14 | * Customizable key and mouse button mappings (in *config.h*) |
| 15 | * Thumbnail mode: grid of selectable previews of all images |
| 16 | * Ability to cache thumbnails for fast re-loading |
| 17 | * Basic support for multi-frame images |
| 18 | * Display image information in window title |
| 19 | |
| 20 | Additional features, that need to be enabled at compile-time (in *config.h*), |
| 21 | because they depend on additional libraries: |
| 22 | |
| 23 | * Load all frames from GIF files and play GIF animations (requires giflib) |
| 24 | * Auto-orientate JPEG images according to their EXIF tags (requires libexif) |

| 37 | Installation |
| 38 | ------------ |
| 39 | sxiv is built using the commands: |
| 40 | |
| 41 | $ make |
| 42 | # make install |
| 43 | |
| 44 | Please note, that the latter one requires root privileges. |
| 45 | By default, sxiv is installed using the prefix "/usr/local", so the full path |
| 46 | of the executable will be "/usr/local/bin/sxiv". |
| 47 | |
| 48 | You can install sxiv into a directory of your choice by changing the second |
| 49 | command to: |
| 50 | |
| 51 | # make PREFIX="/your/dir" install |
| 52 | |
| 53 | The build-time specific settings of sxiv can be found in the file *config.h*. |
| 54 | Please check and change them, so that they fit your needs. |
| 55 | If the file *config.h* does not already exist, then you have to create it with |
| 56 | the following command: |
| 57 | |
| 58 | $ make config.h |
| 59 | |
| 60 | Usage |
| 61 | ----- |
| 62 | sxiv has two modes of operation: image and thumbnail mode. The default is |
| 63 | image mode, in which only the current image is shown. In thumbnail mode a grid |
| 64 | of small previews is displayed, making it easy to choose an image to open. |
| 65 | |
| 66 | sxiv supports the following command-line options: |
| 67 | |
| 68 | -c Remove all orphaned cache files from thumbnail cache and exit |
