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.
