Image Organizer
An image organizer or image management application is application software focused on organising digital images. Image organizers represent one kind of desktop organizer software applications. Image organizer software is primarily focused on improving the user's workflow by facilitating the handling of large numbers of images. In contrast to an image viewer, an image organizer has at least the additional ability to edit the image tags and often also an easy way to upload files to on-line hosting pages. Enterprises may use Digital Asset Management (DAM) solutions to manage larger and broader amounts of digital media. Some programs that come with desktop environments such as gThumb (GNOME) and digiKam (KDE) were originally programmed to be simple image viewers, and have since gained features to be used as image organizer as well. Common image organizers features * Multiple thumbnail previews are viewable on a single screen and printable on a single page. (Contact Sheet) * Ima ...

WebP
WebP is an image 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. Google announced the WebP format in September 2010, and released the first stable version of its supporting library in April 2018. History WebP was first announced by Google on 30 September in 2010 as a new open format for lossy compressed true-color graphics on the web, producing files that were smaller than JPEG files for comparable image quality. It was based on technology which Google had acquired with the purchase of On2 Technologies. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP-related software is released under a BSD free software license. On 3 October 2011, Google added an "Extended File Format" allowing WebP support for animation, ICC profile, XMP and Exif metadata, and tiling (compositing ...

Digital Camera
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras (which are still available). High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can ...

LibTIFF
LibTIFF is a library for reading and writing Tagged Image File Format (abbreviated TIFF) files. The set also contains command line tools for processing TIFFs. It is distributed in source code and can be found as binary builds for all kinds of platforms. The LibTIFF software was originally written by Sam Leffler while working for Silicon Graphics. Features Support for BigTIFF, files larger than 4 GiB, was included for LibTIFF 4.0. Exploits A TIFF file is composed of small descriptor blocks containing offsets into the file which point to a variety of data types. Incorrect offset values can cause programs to attempt to read erroneous portions of the file or attempt to read past the physical end of file. Improperly encoded packet or line lengths within the file can cause rendering programs which lack appropriate boundary checks to overflow their internal buffers. Multiple buffer overflows have been found in LibTIFF. Some of these have also been used to execute unsigned code on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libjpeg
libjpeg is a free library with functions for handling the JPEG image data format. It implements a JPEG codec (encoding and decoding) alongside various utilities for handling JPEG data. It is written in C and distributed as free software together with its source code under the terms of a custom permissive ( BSD-like) free software license, which demands attribution. The original variant is maintained and published by the Independent JPEG Group (IJG). Meanwhile, there are several forks with additional features. JPEG JFIF images are widely used on the Web. The amount of compression can be adjusted to achieve the desired trade-off between file size and visual quality. Utilities The following utility programs are shipped together with libjpeg: ; cjpeg and djpeg: for performing conversions between JPEG and some other popular image file formats. ; rdjpgcom and wrjpgcom: for inserting and extracting textual comments in JPEG files. ; jpegtran: for transformation of existing JPEG fil ...

Transcoding
Transcoding is the direct digital-to-digital conversion of one encoding to another, such as for video data files, audio files (e.g., MP3, WAV), or character encoding (e.g., UTF-8, ISO/IEC 8859). This is usually done in cases where a target device (or workflow) does not support the format or has limited storage capacity that mandates a reduced file size, "Advancements in Compression and Transcoding: 2008 and Beyond", Society of Motion Picture and Television Engineers (SMPTE), 2008, webpageSMPTE-spm or to convert incompatible or obsolete data to a better-supported or modern format. In the analog video world, transcoding can be performed just while files are being searched, as well as for presentation. For example, Cineon and DPX files have been widely used as a common format for digital cinema, but the data size of a two-hour movie is about 8 terabytes (TB). That large size can increase the cost and difficulty of handling movie files. However, transcoding into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Format
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 T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Website
A website (also written as a web site) is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Examples of notable websites are Google, Facebook, Amazon, and Wikipedia. All publicly accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a private network, such as a company's internal website for its employees. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. Users can access websites on a range of devices, including desktops, laptops, tablets, and smartphones. The app used on these devices is called a Web browser. History The World Wide Web (WWW) was created in 1989 by the British CERN computer scientist Tim Berners-Lee. On 30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photograph Album
A photographic album or photo album, is a series of photographic prints collected by an individual person or family in the form of a book. Some book-form photo albums have compartments which the photos may be slipped into; other albums have heavy paper with an abrasive surface covered with clear plastic sheets, on which surface photos can be put. Older style albums often were simply books of heavy paper on which photos could be glued to or attached to with adhesive corners or pages. History The oldest photograph albums in the collection of the Library of Congress in Washington, D.C. are from the 1850s. Early family photo albums were often displayed in the home. "Families who could only afford a couple of pictures would put them into an album, to which other family members would add theirs." Coffee table books / photo-books Coffee table books get their name from the intended purpose of being placed on a coffee table for the entertainment of guests. Coffee table books are pho ...
