nomacs: Easy to use Image Viewer with Basic Editing and Slideshow Support

‘nomacs’ is an open source image viewer that comes with some basic editing options and an intuitive user interface (including transparent buttons and displaying image information in transparent overlay surfaces etc).

It runs in GNU/Linux, MS Windows and Mac OS X platforms, supports a lot of popular image formats (JPEG, PNG, BMP, Raw images etc) and doesn’t consume a lot of system resources as well.

Remember, this is only an image viewer and not an image manager. The memory usage was slightly higher than in ‘Eye of Gnome’ (default image viewer in Ubuntu), but it does include few useful features such as a powerful image resizing window (with previews for comparing withe the source file), send or view images over LAN (network Syncing) and as mentioned above, uses transparent overlay windows.

So when concerning those, in terms of being lightweight, it does reasonably well.

Few main features …

*. Supports a big number of image formats such as JPEG, BMP, PNG, ICO, GIF and many more.

*. Crop, Resize (including the ability to change between different resizing algorithms for an optimal output) Rotate, change the Opacity and a built in ‘pseudo-color’ editor .

*. Easily enable or disable some of its features such as showing ‘meta-data’ (including ‘Exif’ data of digital cameras), image info (Name, Ratings, Creation date etc), playback buttons and thumbnails by using single keyboard shortcuts.

*. Full screen view with a built in Slideshow viewer (change the delay, background color and add/remove image info displayed such as name, creation date etc).

*. Change the thumbnail size, default zoom levels, add/remove data fields from the ‘Exif’ viewer, adjust Synchronizing settings etc.

*. ‘Paste’ images from the ‘Clipboard’ memory.

*. Save thumbnails for faster start-up times.

*. Though its window is already quite simplified, but if you want an even more simpler looking UI, then you can easily disable the Toolbar, the menu, Statusbar, the window frames.

*. Supports running multiple instances.

You can install ‘nomacs’ in Ubuntu 12.10 Quantal Quetzal, 12.04 Precise Pangolin, 11.10 Oneiric Ocelot and 11.04 Natty Narwhal by using its ‘stable’ PPA. For that, open your Terminal and enter the below commands.

sudo add-apt-repository ppa:nomacs/stable

sudo apt-get update

sudo apt-get install nomacs

Though I wouldn’t advice it, but you can use its ‘daily-builds’ PPA for getting the latest/unstable packages if you like.

For that, instead of the above commands, please use the below ones.

sudo add-apt-repository ppa:nomacs/daily

sudo apt-get update

sudo apt-get install nomacs

If you use MS Windows and Mac OS X, then please visit this ‘nomacs’ download page for obtaining the proper installer (that page also has instructions on how to install it in other GNU/Linux distributions such as OpenSuse, Fedora etc). When comparing, I think it looks better in Ubuntu than how it looks in Windows (something looks a bit out of place, perhaps its the toolbars ).

Another thing that’s worth mentioning is that, after enabling showing image thumbnails and mata-data on images for instance, if you exit the application, then the next time you open ‘nomacs, it switches back to its default view and you’ll have to re-enable them again. Unless it’s a ‘feature’ (I hope not :D), it seems like a bug.

Other than that, for a user friendly & a lightweight (somewhat) image viewer, it looks pretty good. Enjoy!.
