NAME
   Fotocx - photo/image editor and collection manager SHORT DESCRIPTION
   Organize and manage a large image collection. Edit and optimize photos and
   other images, add special effects, edit metadata, search images, create a
   photomontage, perform batch operations. Fotocx is a GTK GUI application.
   The included user manual explains Fotocx operation in great detail. LONG DESCRIPTION
      Fotocx is a free Linux program for editing photos or other images and
   managing a large collection. Fotocx has powerful editing tools to correct
   and enhance photos. Fotocx can instantly find desired images within a huge
   collection, based on file/folder names or embedded metadata such as date,
   tags/keywords, title, description, rating, location ... any metadata.
      Image folders can be viewed as a scrolling gallery of thumbnail images.
   Navigation of folders and subfolders is simple and fast. Click 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 or compare multiple images at any scale.
   Thumbnail galleries are also used for image search results and albums.
   Albums are selected images arranged in a desired order. Fotocx has many
   editing tools that go beyond the basics. Images with severe problems
   (underexposed, false colors, blurred, uneven lighting, fog/haze) can be
   brought back to life. Details lost in shadows or haze can be brought out.
   Images with distorted perspective (esp. wide-angle views) can be corrected.
      Fotocx is standards compliant. Nothing done by Fotocx makes images less
   usable with other applications. Fotocx uses your image files wherever they
   are: they are not moved or duplicated. Fotocx does create an index for fast
   image searching, and thumbnail images for fast gallery displays. These add
   typically 2% to overall storage requirements. There is no database to
   manage - the index manages itself.
      Fotocx 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). Convert single RAW files or
   selected batches (click thumbnails from gallery pages).
      Image edit functions are interactive with rapid visual feedback, using
   the full image or a chosen zoom-in area. Undo and Redo can be applied
   serially to all the edits of an image. Intermediate and final results can
   be saved as new files or as new versions (e.g. filename.v02.jpg).
      Areas within an image can be selected and edited separately from the
   background. Areas can be selected using several methods: drag the mouse
   to select and flood into matching tones, follow feature edges, or outline
   an area freehand. Complex feature edges, such as hair or foliage, can be
   accurately selected. Selected areas can be copied and pasted into the same
   or other images, resized, rotated, brightened, etc.
      Layers are not used. Each edit step can be saved separately as a file
   'version'. These can be re-used to make new versions.
      An image can be "mouse painted" onto another image. Paint from a chosen
   source image location to a chosen destination, with optional rescale.
      Batch functions are available to copy, move, rename, resize, upright,
   convert format, convert RAW files, and add or revise metadata.
      Several tools are available to change size and shape: crop, rescale,
   rotate, fix perspective, curve/warp the whole image or selected areas within
   the image. There is a special tool to 'flatten' photos of curved surfaces,
   e.g. a page from a thick book or a poster on a round column.
      Text can be added to an image. Any font and size can be used, any color,
   any angle. The text can have variable transparency, an outline, a shadow,
   or an embossed effect - good for a signature or copyright. Other basic
   markups are available: lines, arrows, box, oval/circle.
      Advanced edit functions: 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, automatically matching brightness
   and color. Photos with a range of exposure values can be combined into an
   HDR image with adjustable contributions. Photos with varying focus depths
   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 mashup
   (montage), using the mouse to position and resize the components and adjust
   overlaps and transparencies.
      Fotocx has a batch scripting 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 selected images.
      Many special effects ('filters') are available to convert a photo into a
   line drawing, sketch, painting, embossing, cartoon, dithered image, mosaic,
   or abstract patterns. Background patterns and textures can be added.
      Images can be rapidly searched using file and folder names or partial
   names, dates, assigned tags, ratings, locations, and any other metadata
   stored in the image. Some data is automatic from the camera (date, location,
   exposure data), and other data can be manually entered (tags, captions ...).
   Search criteria can be used in combination; e.g. find Chicago photos for
   years 2008-2020 containing tags 'Barbara' or 'Barbie'.
      Locations (from a camera GPS sensor 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 markers
   on these maps. Click a marker to get a gallery of the corresponding images.
   You can jump from a given photo to its location on a world map, where you
   can find other photos from the same or nearby locations.
      Albums can be made using selected images from your collection. The files
   are not duplicated. Select images by clicking gallery thumbnails. Arrange
   the images with drag and drop. Albums can be made into slide shows. Choose
   animated transitions between images, pan and zoom effects, and places to
   auto-pause for narration.
      Fotocx includes a comprehensive user manual, also used for interactive
   help: press F1 while using any function in Fotocx to see the corresponding
   topic. You should take the time to read the overview pages. The function
   details can be viewed as needed using F1. CAPABILITIES LIST
