fiv

fiv is a slightly unconventional, general-purpose image browser and viewer.

Features

• Uses a compact thumbnail view, helping you browse collections comfortably.

• Supports BMP, (A)PNG, GIF, TGA, JPEG, WebP directly, plus optionally raw photos, HEIC, AVIF, SVG, X11 cursors and TIFF, or whatever your gdk-pixbuf modules manage to load.

• Employs high-performance file format libraries: Wuffs and libjpeg-turbo.

• Makes use of 30-bit X.org visuals, whenever it’s possible and appropriate.

• Has a notion of pages, and tries to load all included content within files.

Explicit non-goals

• Editing—​that’s what editors are for, be it GIMP or Rawtherapee; nothing beyond the most basic of adjustments is desired.

• Following the latest GNOME HIG to the letter—​header bars are deliberately avoided, for their general user hostility.

• Portability to non-UNIXy systems, although patches are welcome.

• Memory efficiency is secondary to both performance and development time.

Aspirations

Show colours as accurately as hardware allows. Open everything. Be fast. Not necessarily in this order.

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.

Building and Running

Build dependencies: Meson, pkg-config
Runtime dependencies: gtk+-3.0, glib>=2.64, pixman-1, shared-mime-info, libturbojpeg, libwebp, spng>=0.7.0
Optional dependencies: lcms2, LibRaw, librsvg-2.0, xcursor, libheif, libtiff, gdk-pixbuf-2.0, ExifTool

$ git clone --recursive https://git.janouch.name/p/fiv.git
$ meson builddir
$ cd builddir
$ meson compile

Considering the vast amount of dynamically-linked dependencies, do not attempt direct installations. To test the program, help it find its custom thumbnailer:

$ PATH=$(pwd):$PATH ./fiv

Pressing F1 will give you a convenient list of keyboard shortcuts.

Configuration

The standard means to adjust the looks of the program is through GTK+ 3 CSS. As an example, to tightly pack browser items, put the following in your ~/.config/gtk-3.0/gtk.css:

fiv-browser { -FivBrowser-spacing: 0; padding: 0; border: 0; margin: 0; }

Similarly, you can adjust some of the key bindings, as per the command table in fiv-view.h:

@binding-set ViewBindings { bind 'p' { 'command' (print) }; }
fiv-view { -gtk-key-bindings: ViewBindings; }

Should you want to experiment, you will find the GTK+ inspector very helpful.
