| 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. |
| 9 | |
| 10 | Installation |
| 11 | ============ |
| 12 | sxiv is built using the commands: |
| 13 | |
| 14 | $ make |
| 15 | # make install |
| 16 | |
| 17 | Please note, that the latter one requires root privileges. |
| 18 | By default, sxiv is installed using the prefix "/usr/local", so the full path |
| 19 | of the executable will be "/usr/local/bin/sxiv". |
| 20 | |
| 21 | You can install it into a directory of your choice by changing the second |
| 22 | command to: |
| 23 | |
| 24 | # make PREFIX="/your/dir" install |
| 25 | |
| 26 | All build-time specific settings can be found in the file "config.h". Please |
| 27 | check and change them, so that they fit your needs. |
| 28 | |
| 29 | Additional features |
| 30 | ------------------- |
| 31 | |
| 32 | The XFLAGS and XLIBS macros/environment variables control which additional |
| 33 | features (i.e. non-default compile-time features) should be enabled and |
| 34 | included during compilation. |
| 35 | |
| 36 | The following table lists the available additional features--the column |
| 37 | *Requires* indicates, which libraries need to be installed for a feature; the |
| 38 | columns *XFLAGS* and *XLIBS* show, what needs to be added to these environment |
| 39 | variables to enable the corresponding feature: |
| 40 | |
| 41 | Feature | Requires | XFLAGS | XLIBS |
| 42 | ----------------------------------+----------+----------------+-------- |
| 43 | GIF support: Load all frames and | giflib | -DGIF_SUPPORT | -lgif |
| 44 | play animations of GIF files | | | |
| 45 | ----------------------------------+----------+----------------+-------- |
| 46 | EXIF support: auto-orientate JPEG | libexif | -DEXIF_SUPPORT | -lexif |
| 47 | files according to their EXIF tag | | | |
| 48 | |
| 49 | For instance, to enable GIF support, the giflib library needs to be installed |
| 50 | on your system and you need to execute the following shell commands before |
| 51 | running make: |
| 52 | |
| 53 | $ export XFLAGS=-DGIF_SUPPORT |
| 54 | $ export XLIBS=-lgif |
| 55 | |
| 56 | Usage |
| 57 | ===== |
| 58 | sxiv has two modes of operation: image and thumbnail mode. The default is image |
| 59 | mode, in which only the current image is shown. In thumbnail mode a grid of |
| 60 | small previews is displayed, making it easy to choose an image to open. |
| 61 | |
| 62 | sxiv supports the following command-line options: |
| 63 | |
| 64 | -c Remove all orphaned cache files from thumbnail cache and exit |
| 65 | -d Scale all images to 100%, but fit large images into window |
| 66 | -F Use size-hints to make the window fixed/floating |
| 67 | -f Start in fullscreen mode |
| 68 | -g GEOMETRY Set window position and size |
| 69 | (see section GEOMETRY SPECIFICATIONS of X(7)) |
| 70 | -n NUM Start at picture NUM |
| 71 | -p Pixelize, i.e. turn off image anti-aliasing |
| 72 | -q Be quiet, disable warnings |
| 73 | -r Search given directories recursively for images |
| 74 | -s Scale all images to fit into window |
| 75 | -t Start in thumbnail mode |
| 76 | -v Print version information and exit |
| 77 | -Z Same as `-z 100' |
| 78 | -z ZOOM Scale all images to current zoom level, use ZOOM at startup |
| 79 | |

| 81 | thumbnail mode are denoted via brackets: |
