F-Spot
F-Spot is a discontinued image organizer, that was designed to provide personal photo management for the GNOME desktop environment. The name is a play on the word F-Stop. F-Spot can be used for basic photo editing and management. History The F-Spot project was started by Ettore Perazzoli and was maintained by Stephen Shaw. F-Spot is written in the C# programming language using Mono. Before its discontinuation in 2017, F-Spot was the standard image tool for several GNOME based distributions. Before that, Fedora replaced F-Spot with Shotwell in Fedora 13. Ubuntu also replaced it with Shotwell in 10.10 Maverick Meerkat. Features F-Spot aimed to have an interface that is simple to use but also facilitates advanced features such as tagging images, and displaying and exporting image metadata in Exif and XMP formats. F-Spot has been noted as being similar to iPhoto. All major photographic image formats are supported, including JPEG, PNG, TIFF, DNG, GIF, SVG and PPM, as well ...

Shotwell (software)
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. In 2019, Shotwell was the target of a predatory lawsuit by Rothschild Patent Imaging against the GNOME Foundation claiming a patent infringement related to the use of WiFi to transfer photographic images. The case was resolved through agreement in 2020 and the patent itself invalidated in 2022 following a legal challenge from the open source development community. Features Shotwell can import photos and videos from a digital camera directly. Shotwell automatically groups photos and videos by date, and supports tagging. Its image editing features allow users to straighten, crop, eliminate red eye, and adjust levels and color balance. It also features an auto "enhance" option that wil ...

Ettore Perazzoli
Ettore Perazzoli (June 15, 1974 – December 10, 2003) was an Italian free software developer. Biography Born in Milan, he studied Engineering at the Polytechnic University. He wrote a port of x64, a Commodore 64 emulator for Unix, to DOS, thus turning it into a cross-platform emulator, which was renamed to VICE. He has been a maintainer of VICE for many years, and started the Microsoft Windows port, which is now the most popular version of VICE. He then started contributing to GNOME, a Linux desktop environment. He helped in writing GtkHTML, Nautilus and Evolution. Close friend of Nat Friedman and Miguel de Icaza, he was invited by them to work for the company they founded, Ximian. He accepted and in 2001 moved to Boston, United States, where Ximian was headquartered. At Ximian he led the effort to create Evolution and remained the project manager until he died. He started writing an application for managing digital photo albums, in C#, for personal use. On November 8, 2003 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mono (software)
Mono is a free and open-source software framework that aims to run software made for the .NET Framework on Linux and other OSes. Originally by Ximian which was acquired by Novell, it was later developed by Xamarin which was acquired by Microsoft. In August 2024, Microsoft transferred ownership of Mono to Wine_(software), WineHQ. History When Microsoft first announced their .NET Framework in June 2000 it was described as "a new platform based on Internet standards", and in December of that year the underlying Common Language Infrastructure was published as an open standard, "ECMA-335", opening up the potential for independent implementations. Miguel de Icaza of Ximian believed that .NET had the potential to increase programmer productivity and began investigating whether a Linux version was feasible. Recognizing that their small team could not expect to build and support a full product, they launched the Mono open-source project, on July 19, 2001, at the O'Reilly Media, O'Reilly ...

Extensible Metadata Platform
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. XMP standardizes a data model, a serialization format and core properties for the definition and processing of extensible metadata. It also provides guidelines for embedding XMP information into popular image, video and document file formats, such as JPEG and PDF, without breaking their readability by applications that do not support XMP. Therefore, the non-XMP metadata have to be reconciled with the XMP properties. Although metadata can alternatively be stored in a sidecar file, embedding metadata avoids problems that occur when metadata is stored separately. The XMP data model, serialization format and core properties is published by the International Organization for Standardization as ISO 16684-1:2012 standard. Data model The defined XMP data model can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scalable Vector Graphics
Scalable Vector Graphics (SVG) is an XML-based vector graphics format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by most web browsers. If used for images, SVG can host scripts or CSS, potentially leading to cross-site scripting attacks or other security vulnerabilities. History SVG has been in development within the World Wide Web Consortium (W3C) since 1999 after six competing proposals for vector graphics languages had been submitted to the consortium during 1998 (see below). The early SVG Working Group decided not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics Interchange Format
The Graphics Interchange Format (GIF; or , ) is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite and released on June 15, 1987. The format can contain up to 8 bits per pixel, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It can also represent multiple images in a file, which can be used for animations, and allows a separate palette of up to 256 colors for each frame. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients but well-suited for simpler images such as graphics or logos with solid areas of color. GIF images are compressed using the Lempel–Ziv–Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. While once in widespread usage on the World Wide Web because of i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Negative
Digital Negative (DNG) is an Open format, open, lossless raw image format developed by Adobe Systems, Adobe and used for digital photography. It was launched on September 27, 2004. The launch was accompanied by the first version of the DNG specification,. plus various products, including a free-of-charge DNG converter utility. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the launch supports DNG.. DNG is based on the Tag Image File Format / Electronic Photography, TIFF/EP Open standard, standard format, and mandates significant use of metadata (computing), metadata. The specification of the file format is open and not subject to any intellectual property restrictions or patents.. Rationale for DNG Adobe states that, given the existence of a wide variety of camera-brand-specific raw image formats, it introduced DNG as a standardized and backward-compatible universal file format. It is based on the TIFF 6.0 standard. Various pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

Portable Network Graphics
Portable Network Graphics (PNG, officially pronounced , colloquially pronounced ) is a raster graphics, raster-graphics file graphics file format, format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). PNG supports palette-based images (with palettes of 24-bit RGB color model, RGB or 32-bit RGBA color space, RGBA colors), grayscale images (with or without an Alpha compositing, alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore, non-RGB color spaces such as CMYK color model, CMYK are not supported. A PNG file contains a single image in an extensible structure of ''chunks'', encoding the basic pixels and other information such as textual comments and Integrity checker, integrity checks documented in Request for Comments ...

JPEG
JPEG ( , short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable trade off between storage size and image quality. JPEG typically achieves 10:1 compression with noticeable, but widely agreed to be acceptable perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The Joint Photographic Experts Group created the standard in 1992, based on the discrete cosine transform (DCT) algorithm. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media. JPEG compression is used in a number of ...

Image File Formats
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or lossless compression. For graphic design applications, vector formats are often used. Some image file formats support transparency. Raster formats are for 2D images. A 3D image can be represented within a 2D format, as in a stereogram or autostereogram, but this 3D image will not be a true light field, and thereby may cause the vergence-accommodation conflict. Image files are composed of digital data in one of these formats so that the data can be displayed on a digital (computer) display or printed out using a printer. A common method for displaying digital image information has historically been rasterization. Image file sizes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
