gThumb is a free and open-source image viewer and image organizer with options to edit images. [2] It is designed to have a clean and simple user interface and follows GNOME HIG, it integrates well with the GNOME desktop environment.
gThumb allows the filesystem to be browsed for images. They can be organized into catalogs, or viewed as a slideshow. Folders and catalogs can be bookmarked, and comments can be added to images.
Via gPhoto it can also acquire data directly from digital cameras.
gThumb offers a certain range of image editing operations suited for digital photography, such as the change of image hue, saturation, lightness, contrast or the adjustment of colors and sharpness. It can also crop, scale and rotate images by 90° or custom angles, and it features a red-eye effect removal function. Manipulated images can be saved in the formats JPEG, PNG, TIFF, .tga, avif, heif and WebP. [3]
gThumb can export web-based photograph albums with various theme templates. These albums can be uploaded to a website, providing a very simple mechanism for publishing collections of photos on the web.
gThumb also includes many basic features such as copying, moving, deleting or duplicating images, printing, zooming, format transcoding, and batch renaming.
gThumb only requires glib (>= 2.36.0), gtk (>= 3.16), gthread, gmodule and gio-unix. Libraries that are not mandatory but possible include exiv2, libjpeg, LibTIFF, LibRaw, and JPEG XL's libjxl.
The first public version was 0.2 in 2001.
It was originally based on GQView. Starting from version 2.12.0 gThumb allows users to export images to various websites. Version 3.0.0 is based on GTK version 3, and supports high quality SVG zoom. [4]
Portable Network Graphics is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF)—unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF".
GNOME Web, called Epiphany until 2012 and still known by that code name, is a free and open-source web browser based on the GTK port of Apple's WebKit rendering engine, called WebKitGTK. It is developed by the GNOME project for Unix-like systems. It is the default and official web browser of GNOME, and part of the GNOME Core Applications.
CodedColor is a bitmap graphics editor and image organizer for computers running the Microsoft Windows operating system, and is published by 1STEIN.
Inkscape is a free and open-source vector graphics editor for GNU/Linux, Windows and macOS. It offers a rich set of features and is widely used for both artistic and technical illustrations such as cartoons, clip art, logos, typography, diagramming and flowcharting. It uses vector graphics to allow for sharp printouts and renderings at unlimited resolution and is not bound to a fixed number of pixels like raster graphics. Inkscape uses the standardized Scalable Vector Graphics (SVG) file format as its main format, which is supported by many other applications including web browsers. It can import and export various other file formats, including SVG, AI, EPS, PDF, PS and PNG.
An image server is web server software which specializes in delivering images. However, not all image servers support HTTP or can be used on web sites.
F-Spot is a slowly maintained image organizer, designed to provide personal photo management for the GNOME desktop environment. The name is a play on the word F-Stop.
Eye of GNOME is the official and default image viewer for the GNOME desktop environment, where it is also known as Image Viewer. There is also another official image viewer for GNOME called gThumb that has more advanced features like image organizing and image editing functions.
Gwenview is an image viewer for Unix-like systems and is released as part of the KDE Applications bundle. The current maintainer is Aurélien Gâteau. The word "Gwen" means "white" in the Breton language and is commonly used as a first name.
Raster graphics editors can be compared by many variables, including availability.
The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets.
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are so named because they are not yet processed, and contain large amounts of potentially redundant data. Normally, the image is processed by a raw converter, in a wide-gamut internal color space where precise adjustments can be made before conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment.
Dreamlinux was a Brazilian computer operating system based on Debian Linux. It can boot as a live CD, from USB flash drive, or can be installed on a hard drive. The distribution's GUI aims to have a centered animated toolbar. As of October 2012, The Dreamlinux Project has been discontinued.
FastPictureViewer is a freemium image viewer for Windows XP and later. Its aim is to facilitate quick review, rating and annotation of large quantities of digital images in the early steps of the digital workflow, with an emphasis on simplicity and speed. As an app with a freemium license, a basic version is available cost-free for personal, non-profit or educational uses, while a commercial license is required for the professional version with additional features. The basic version starts as a full version trial.
RawTherapee is application software for processing photographs in raw image formats, as created by many digital cameras. It comprises a subset of image editing operations specifically aimed at non-destructive post-production of raw photos and is primarily focused on improving a photographer's workflow by facilitating the handling of large numbers of images. It is notable for the advanced control it gives the user over the demosaicing and developing process. It is cross-platform, with versions for Microsoft Windows, macOS and Linux.
Shotwell is an image organizer designed to provide personal photo management for the GNOME desktop environment. In 2010, it replaced F-Spot as the standard image tool for several GNOME-based Linux distributions, including Fedora in version 13 and Ubuntu in its 10.10 Maverick Meerkat release.
WebP is a raster graphics file format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, as well as animation and alpha transparency.
Cinnamon is a free and open-source desktop environment for Linux and Unix-like operating systems, deriving from GNOME 3 but following traditional desktop metaphor conventions.
Darktable is a free and open-source photography application program and raw developer. Rather than being a raster graphics editor like Adobe Photoshop or GIMP, it comprises a subset of image editing operations specifically aimed at non-destructive raw image post-production. It is primarily focused on improving a photographer's workflow by facilitating the handling of large numbers of images. It is freely available in versions tailored for most major Linux distributions, macOS, Solaris and Windows and is released under the GPL-3.0-or-later.
JPEG XL is a royalty-free raster-graphics file format that supports both lossy and lossless compression. It is designed to outperform existing raster formats and thus become their universal replacement.
