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 link:fiv-view.h[]:
|

|

@binding-set ViewBindings { bind 'p' { 'command' (print) }; }

which can be invoked from within the program by pressing F1.

|
||||
<h2>Introduction</h2>
|
||||
|
||||
<p><i>fiv</i> is a general-purpose image browser and viewer. This document will
|
||||
guide you through the application and help to familiarize you with it.
|
||||
|
||||
<h2>Controls</h2>
|
||||
|
||||
<p><i>fiv</i> is designed with computer mice having dedicated forwards/backwards
|
||||
and page up/down buttons in mind, such as SteelSeries Sensei series. Ozone Neon
|
||||
series may also be mapped this way. Your experience may be degraded with other
|
||||
kinds of devices.
|
||||
|
||||
<p>Controls should generally be accessible through the keyboard. Pressing Ctrl+?
|
||||
will give you a convenient overview of all shortcuts. In addition to these,
|
||||
remember that you may often use Ctrl+Tab and F6 to navigate to different groups
|
||||
of widgets.
|
||||
|
||||
<h2>Browser</h2>
|
||||
|
||||
<p><i>fiv</i> normally starts in a file browser view. On the left side of the
|
||||
window, you'll find your GTK+ bookmarks, mounted locations as recognized by
|
||||
GVfs, an item for entering arbitrary filesystem paths or URIs, view controls,
|
||||
and finally breadcrumbs leading to the currently opened directory, as well as
|
||||
its descendants.
|
||||
|
||||
<p>You can open items in a new window either by middle clicking on them either
|
||||
directly, or with the Ctrl key pressed down. Right clicking the directory view
|
||||
offers a context menu for opening files, or even the directory itself,
|
||||
in a different application.
|
||||
|
||||
<h2>Viewer</h2>
|
||||
|
||||
<p>The image viewer may be both entered (so long as you have a file selected)
|
||||
and exited using the Enter key. This way you may easily switch between the two
|
||||
modes. When using the mouse, the forwards and backwards buttons will fulfill
|
||||
the same function.
|
||||
|
||||
<p>Double clicking the image switches full-screen view, and the mouse wheel
|
||||
adjusts the zoom level.
|
||||
|
||||
<p>Files are iterated in the same order, and using the same filtering as in
|
||||
the browser.
|
||||
|
||||
<p>
|
||||
|
||||
<h2>File formats</h2>
|
||||
|
||||
<p>The list of all supported file formats may be obtained by running:
|
||||
|
||||
<pre>
|
||||
fiv --list-supported-media-types
|
||||
</pre>
|
||||
|
||||
Unless it has been turned off in your installation, you may extend it through
|
||||
gdk-pixbuf modules.
|
||||
|
||||
<h2>Thumbnails</h2>
|
||||
|
||||
<p><i>fiv</i> uses a custom way of storing thumbnails, and doesn't currently
|
||||
provide any means of invalidating this cache. Should you find out that your
|
||||
<i>~/.cache/thumbnails</i> directory is taking up too much space, run:
|
||||
|
||||
<pre>
|
||||
rm -rf ~/.cache/thumbnails/wide-*
|
||||
</pre>
|
||||
|
||||
<h2>Configuration</h2>
|
||||
|
||||
<p>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
|
||||
<i>~/.config/gtk-3.0/gtk.css</i>:
|
||||
|
||||
<pre>
|
||||
fiv-browser { -FivBrowser-spacing: 0; padding: 0; border: 0; margin: 0; }
|
||||
</pre>
|
||||
|
||||
<p>Similarly, you can adjust some of the key bindings, as per the command table
|
||||
in the <i>fiv-view.h</i> source file:
|
||||
|
||||
<pre>
|
||||
@binding-set ViewBindings { bind 'p' { 'command' (print) }; }
|
||||
fiv-view { -gtk-key-bindings: ViewBindings; }
|
||||
</pre>
|
||||
|
||||
<p>Should you want to experiment, you will find the GTK+ inspector very helpful.
