<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.
|
||
|
||
<h2>File formats</h2>
|
||
|
||
<p>The list of all supported file formats may be obtained by running:
|
||
|
||
<pre>
|
||
fiv --list-supported-media-types
|
||
</pre>
|
||
|
||
<p>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 means of storing thumbnails, and doesn't currently
|
||
invalidate this cache automatically. Should you find out that your
|
||
<i>~/.cache/thumbnails</i> directory is taking up too much space, run:
|
||
|
||
<pre>
|
||
fiv --invalidate-cache
|
||
</pre>
|
||
|
||
<p>to trim it down. Alternatively, if you want to get rid of <i>all</i>
|
||
thumbnails, even for existing images:
|
||
|
||
<pre>
|
||
rm -rf ~/.cache/thumbnails/wide-*
|
||
</pre>
|
||
|
||
<h2>Configuration</h2>
|
||
|
||
<p>The few configuration options <i>fiv</i> has can be adjusted using
|
||
<i>dconf-editor</i>, which can be launched in the appropriate location from
|
||
within the application by pressing Ctrl+,. For command line usage, there is
|
||
the <i>gsettings</i> utility:
|
||
|
||
<pre>
|
||
gsettings list-recursively name.janouch.fiv
|
||
</pre>
|
||
|
||
<p>To make your changes take effect, restart <i>fiv</i>.
|
||
|
||
<h3>Theming</h3>
|
||
|
||
<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.

|

toc += '<li><p><a href="#' + name + '">' + all[i].innerHTML + '</a></li>'
|

all[i].id = name
|

all[i].innerHTML = (i + 1) + '. ' + all[i].innerHTML
