Fotoxx 13.12 released with faster workflow, upgrade in Ubuntu

Last updated: December 2, 2013

 

Fotoxx, the free and open source photo editing software recently released version 13.12 with UI revision for faster workflow when processing multiple photos.

Full changes in Fotoxx 13.12:

The user interface was revised for faster workflow when processing multiple photos:

  • An edit function can be started without closing a prior active edit function. The prior edit becomes the new base and an undo/redo position is added automatically.
  • You can step through a series of images with an open edit function. Apply the function to an image or pass over by pressing the [next] button.
  • Brightness and color functions can recall prior settings for faster application to other photos made under the same lighting conditions.

Other changes:

  • RAW files are now edited like other image files. Auto-copy to TIFF–16 is no longer done. Edit as usual and save in the desired format (TIFF/PNG/JPEG, 8/16 bit color).
  • Add Text: new option: retrieve and edit metadata caption/comments.
  • Captions: new option: show metadata caption/comments above each image.
  • Move Collections is more flexible: any pathname segment can be replaced.
  • Some intermediate files now use ramdisk for a small performance gain.
  • Mashup: move layout images in 1-pixel steps with the keyboard arrow keys.
  • Mashup: internal speedups, especially when painting transparency.
  • New Slide Show transition type: double doors open from the middle.
  • Log file output was made always current, like a terminal session.

Bug Fixes:

  • Unsaved edits were lost if the [next] button was used beyond the last image file.
  • Curve nodes were lost when reloading saved complex edit curves.
  • Mashup: fix erratic overlay image corner drag behavior.

Install Fotoxx in Ubuntu:

The GetDeb repository contains the latest release for Ubuntu 13.10, Ubuntu 12.04 and their derivatives. To add the repository, run commands below in terminal one by one (Ctrl+Alt+T):

wget http://archive.getdeb.net/install_deb/getdeb-repository_0.1-1~getdeb1_all.deb

sudo dpkg -i getdeb-repository_0.1-1~getdeb1_all.deb

For Linux Mint there’s an option under “Software Sources -> Additional repositories” to enable Getdeb.

After that, install Fotoxx from Ubuntu Software Center after checking for updates. Or run commands below instead:

sudo apt-get update; sudo apt-get install fotoxx

    Last updated: November 30, 2013

     

    Since Ubuntu 13.10, there’s an indicator applet on top panel which allows to quickly switch between keyboard layouts for various languages.

    If you find that the keyboard indicator is useless, you can easily remove the applet from top panel by following the steps below:

    1. Open System Settings from Unity Launcher or from top-right corner shutdown menu. Then click on Text Entry

    2. In the bottom of the window you’ll see “Show current input source in the menu bar” which is enabled by default. Uncheck the box and the indicator applet will disappear instantly.

    That’s it. Enjoy!
