Geeqie and GThumb advanced picture viewing Picasa
alternative for GNU / Linux - GQView on Debian now a meta package
for Geeqie
I'm currently learning some basic graphic design - reading GIMP's
documentation etc. While reading
http://docs.gimp.org, I saw
a reference to
Gthumb and
GQView picture viewing
apps, so I thought of installing them on my
Debian Linux
GQView has a lot of santimental value to me as it reminds me
of the the old times when I used
gqview as a default picture
viewing program on a old machine running
Debian Woody Linux
with
Window Maker as desktop environment.
I wanted to see how GQView looks nowdays so installed it:
noah:~# apt-get --yes install gqview
And onwards launch it:
hipo@noah:~/Desktop$ gqview
This is a compatibility alias for Geeqie!
Please use /usr/bin/geeqie instead!
Creating Geeqie dir:/home/hipo/.config/geeqie
Creating Geeqie
dir:/home/hipo/.local/share/geeqie/collections
Creating Geeqie dir:/home/hipo/.cache/geeqie/thumbnails
Creating Geeqie
dir:/home/hipo/.local/share/geeqie/metadata
What poped up instead of
gqview is
Geeqie - a picture viewer nowdays available on a default Slackware
Linux install.
Fedora, CentOS users will have to build geekie from its source, as
of time of writting there is no available rpm package.
It was new to me
Gqview is no longer developed, its dev is
forked (because its head developer is not reachable any more).
Hence QGView continues to live on nowdays under the hood of
Geekie
As you can see from the prior screenshot
Geeqie has very
similar interface to
GQView. Going through the interface,
I've found it has much more features than
GQView. You see
one of the many new nice features is the support for drawing
Image Histograms.
There are few type of Histograms to display in
Geekiq,
available by navigating to:
View -> Image Overlay
Even if you're not familiar with
Image histograms, probably
you have seen them appear on a
digital camera while browsing
in menus. Its likely you didn't know what you saw a digital camera
display is a histogram.
Anyways being not familiar with histograms is perfectly fine as for
most of us (regular) users
image historograms doesn't make
much sense.
BTW Histograms are very useful for pro Photographers.
Photographers can use them as an aid to show the
distribution of picture "tones" captured, and whether image detail
has been lost to blown-out highlights or blacked-out shadows.
Interesting fact concerning "reading" and understanding
Histograms is on a Histogram for a very dark image the
majority of data points are on the left side and center of the
graph, whether histogram for a very bright image with few dark
areas and/or shadows will have most of its data points located on
the right side and center of the graph.
With this said in mind, you can see, the above
Geeqie
picture visibile histogram obviously has most of its data
concentrated on the
right and the center so this means the
histogram belongs to a bright pic. Well, Actually you can see this
without a histogram too ;)
Though Image Histograms might seem pretty useles they're very much
needed in Professional
Graphic Manipulation. For instance
for correction of image color gamma or manually adjusting the
brightness for each picture pixel brightness.
So Enough with histograms, I will switch now to a short review of
Gthumb
Since I haven't used/seen
Gthumb "for ages", I was also
curious how the program looks nowdays. I did not needed to install
gthumb, as I had it installed already on my notebook. I assume
gthumb package was installed as some package dependency or I
did it install some very long time ago and I forgot.
For people who didn't have it install do:
noah:~# apt-get --yes install gthumb
...
This installs a
Gthumb version
2.12.2. The current
latest stable Gthumb release is way ahead from the existing
deb stable package, the latest available version on sourceforge is
2.7.4
Ubuntu gthumb latest packages would probably be newer than my
debian installed one, so Ubuntu users can have the joy to use a
newer version of gthumb...
gthumb is also installable for Fedora and CentOS users by
default from default assigned package repos:
To install on RPM based Linux distro:
[root@centos:~ ]# yum -y install centos
...
Once installed, I ran it via a gnome run application shortcut
ALT+F2 and typed:
gthumb
If you're more of a gui user than me you can run it also through
GNOME menus:
Applications -> Graphics -> Gthumb Image
Viewer
You see
gthumb appears, quite similar in "look&feel" to
Geeqie.
I went through the program options just for the sake to compare
with
Geeqie. Based on the fact
Geeqie seems to have
more functionality it is probably superior and better choice for
people looking for professional image vieweing / editting.However
there are some other aspects I've noticed, where it lacks behind
Gthumb.
Gthumb has few great functionality which unfortunately as of
time of writting are missing or hardly achievable in
Geeqie
1. Bookmarking pictures.
This allows for your favourite pictures to be bookmarked in the
same way as bookmarks work in a browser, really neat feature.
2. Share functionality
Share button is located on the rightest upper corner and
makes sharing with major web storage places easy.
Through the
Share button, you can export (share) your
pictures
directly in Picasa, Facebook,Flickr and
Photobucket.
Through this share button it is also possible to "share your photos
on a CD or DVD", - burn them on a CD/DVD directly from gthumb. This
is doable via:
One other
Gthumb advantagle is its extensibility. It has a
powerful plugin system. Many of the features it has are already
there thanks to its enabled extensions.
3. Photo Tagging
Nowdays tagging, photos has become so popular with the boom of
facebook tagging. Gthumb has a relatively easy to use image tagging
integrated.
tagging a picture is done by simply going through the picture and
selecting it with the (rightest located mouse button).
There is a list of few already predefined tags, which can be used
to tag images. Assigning more tags is done via menu:
Tags -> Other
4. Organizing pictures
Through the Organize button located right below the
Share
button, one can easily organize his picture collections, based on
few criterias.
The organize easy feature is not so important for not people, who
are not in depth in photographing but for professional
photographers this is an absolute necessity. For people who are
image freaks and store tens of thousands of pictures organizing
pictures for easy later retrieval is really nice.
To sum it, up
Geeqie and
Gthumb are richer in
functionality if compared to GNOME's default pic viewer (eye of the
gnome) -
eog.
Geeqie, as the name suggests is more for geek oriented and
has a lot of great options which can serve well for advanced
computer users. For an ordinary desktop user however it will
probably be not easy to "digest". Gthumb on the other hand is ideal
for anyone who prefers gui convenience. Gthumb is a good option for
anyone looking for some similar to
Picasa free
software program that is feature rich and easy to use. For
people who has to review a dozens of pictures daily, associating
one of the two as a default picture viewer will probably be
useful.
