    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:
