Fotoxx is a free Linux program for editing photos or other images and managing a large collection. Image directories (folders) can be viewed as a scrolling gallery of thumbnail images. Navigating directories and subdirectories is simple and fast. Click on a thumbnail for a full window view of the image. The image can be zoomed, panned and scrolled using the mouse. Gallery thumbnails can vary from small to huge. Popup windows can be used to view multiple images at any scale. Galleries are also used to display image search results and albums. Albums are ordered collections of selected images. Fotoxx has many editing tools that go beyond the basics. Images with severe problems (underexposed, false colors, blurred, uneven lighting, hazy/foggy background) can be brought back to life. Details lost in shadows or haze can be brought out.

Fotoxx is standards compliant. Nothing done by Fotoxx makes your images less usable with other applications. Fotoxx uses your image files wherever they are: they are not moved or duplicated. Fotoxx does create an index for fast image searching, and thumbnail images for fast gallery displays. These add typically 1-2% to overall storage requirements.

Fotoxx can import RAW images and perform all processing in deep color (24 bits per color used internally). Edited images can be saved as JPEG, TIFF (8/16 bits/color), or PNG (8/16 bits).

Image edit functions are interactive, giving rapid response to adjustments using the full image or a chosen area. Undo and Redo can be applied serially to all the edits of an image. Intermediate and final results can be saved as file versions.

Objects or areas within an image can be selected and edited separately (select by matching tones, following edges, or freehand draw). There are no layers - results are seen instantly in the edited areas. Selected areas can be copied and pasted into other images, resized, turned, brightened, etc.

Batch functions are available to copy, move, rename, resize, upright, convert format, and add/revise metadata.

Several tools are available to change size and shape: crop, resize, rotate, fix perspective, flatten curved book pages, curve/warp the whole image or selected areas within the image.

Dust spots from old slides or photos can be removed, roadside trash or power lines can be erased. Panoramas can be made by stitching photos together seamlessly, matching brightness and color. Photos with a range of exposure values can be combined into an HDR image with adjustable contributions. Photos with varying depth of focus can be combined into an image that is sharp over the combined range. Photos of one scene taken at different moments can be combined to remove passing autos or tourists. Multiple photos made under low light conditions can be combined to reduce noise. Images and text can be combined into a montage, using the mouse to position and resize the elements and adjust overlaps and transparencies.

Fotoxx has a batch edit tool to speed the processing of multiple images requiring the same edits: record the edits made to a base image and then apply these edits automatically to any number of images.

Artistic effects are available to convert a photo into a line drawing, sketch, painting, embossing, cartoon, dot image, or mosaic. Background patterns can be added; e.g. the texture of artist's linen.

Images can be rapidly searched using file and folder names, dates, assigned tags, ratings and other data stored in the image metadata, from the camera or manually edited. All search criteria can be used in combination; e.g. find Chicago photos for years 2002-2005 containing tags "Barbara" or "Barbie". Locations (from a camera GPS receiver or entered manually) can also be searched. You can view a map of any region in the world, at any scale, using an internet map service. Images having location data show as red dots on these maps. You can click the dots to get a gallery display of the corresponding images, which can be viewed full size or edited. Local map files of the world, each continent, and some countries are also available, and you can add your own maps at any scale. Local maps have no dependency on the internet. You can jump from a given photo to its position on a world map, where you can find other photos from the same or nearby positions.

Slide shows can be prepared. Choose animated transitions between images, pan and zoom effects, and places to auto-pause for narration.

Fotoxx includes a comprehensive user manual that also serves as interactive help on a function by function basis. You should take the time to read the overview pages. The function details can be viewed as needed for reference.

  • Web maps may also be used to view any location in the world at any scale
    (works well if you have a good internet connection).

    automatically inherit image location markers like the other maps.
  • Fotoxx metadata is standards compliant and usable with other apps (no lock-in).

Other Functions

  • Build a custom graphic menu in a popup window. Add your most frequently
    used functions and arrange their layout using the mouse.
  • Slide-show mode: arty transitions, optional keyboard navigation, zoom in/out.
  • Select images from the thumbnail gallery browser, burn a DVD or BlueRay.
  • Brightness distribution graph, updated live with image edits.
  • Batch functions: rename, resize, copy/move, change format, revise metadata.
  • Batch convert RAW files to JPEG, TIFF (8/16 bits), or PNG (8/16 bits).

Languages 
The GUI is available in English, Catalan, French, German, Italian, Portuguese, Spanish. A comprehensive user guide is provided in English. If you can help with translations, see the topic Translations in the User Guide. This is technically easy but would require several days of work: there are over 1200 text strings to translate.

Hardware  
Fotoxx works best on a strong PC (2+ processor cores, 8+ GB). Weaker computers may be quite slow or may fail to edit very large images. 64-bit Linux is required. Monitors used for photo editing should be at least HD in size and have good color accuracy (most do not).

Performance and Limitations
Most image edit functions respond within a second on a strong PC and for images up to 20 megapixels. 100 megapixel images can be processed on a PC with 8+ GB RAM. Some composite functions (panorama, HDR) may need a minute or more when combining many large images. Search speed is generally below 2 seconds for collections up to 200,000 images.
