Page Zooming
In computing, page zooming is the ability to zoom in and out a document or image at page level. It is usually found in applications related to document layout and publishing, e.g. word processing and spreadsheet programs, and is also found in web browsers. It can be used to improve accessibility for people with visual impairment and people using mobile devices which have a relatively small screen. Different modes There are several notably different modes of page zooming: * ''Text resizing'' resizes the text by increasing or decreasing the font size, with wrapping to avoid horizontal scrolling, leaving the size of the images the same. This was available in old web browsers and browsers with special extensions. * Another mode resizes all objects (text, images, boxes, embedded videos, etc.) and performs a layout shift / reflow such that the page still fits horizontally on the screen. In web browsers, this is available through and . * ''Visual viewport zoom'' resizes all objects w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering. The term ''computing'' is also synonymous with counting and calculation, calculating. In earlier times, it was used in reference to the action performed by Mechanical computer, mechanical computing machines, and before that, to Computer (occupation), human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. ...

Reflowable Document
A reflowable document is a type of electronic document that can adapt its presentation to the output device. Typical prepress or fixed page size output formats like PostScript or PDF are not reflowable during the actual printing process because the page is not resized. For end users, the World Wide Web standard, HTML is a reflowable format as is the case with any resizable electronic page format. In contrast to end user terminology, the notion of reflow is sometimes used to discuss desktop publishing program features for print publication page layout such as automatically balancing the amount of text in a number of columns. Reflow is not limited to text; 21st century scorewriters enable music notation to be reflowed between systems and pages in a similar way to how text reflows between lines and pages. Examples Besides HTML, commercially available systems include: * EPUB is a simple reflowable format that allows a single column with inline images, in many ways similar to a ...

Resolution Independence
Resolution independence is where elements on a computer screen are rendered at sizes independent from the pixel grid, resulting in a graphical user interface that is displayed at a consistent physical size, regardless of the resolution of the screen. Concept As early as 1978, the typesetting system TeX due to Donald Knuth introduced resolution independence into the world of computers. The intended view can be rendered beyond the atomic resolution without any artifacts, and the automatic typesetting decisions are guaranteed to be identical on any computer up to an error less than the diameter of an atom. This pioneering system has a corresponding font system, Metafont, which provides suitable fonts of the same high standards of resolution independence. The terminology device independent file format (DVI) is the file format of Donald Knuth's pioneering TeX system. The content of such a file can be interpreted at any resolution without any artifacts, even at very high resolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blu-ray Disc
Blu-ray (Blu-ray Disc or BD) is a Digital media, digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X and Series S, Xbox Series X. The name refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs, resulting in an increased capacity. The polycarbonate disc is in diameter and thick, the same size as DVDs and Compact disc, CDs. Conventional (or "pre-BDXL") Blu-ray discs contain 25gigabyte, GB per layer, with dual-layer discs (50GB) being the industry standard for fe ...

Scroll Bar
A scrollbar is an interaction technique or widget in which continuous text, pictures, or any other content can be scrolled in a predetermined direction (up, down, left, or right) on a computer display, window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time. It offers a solution to the problem of navigation to a known or unknown location within a two-dimensional information space. It was also known as a handle in the very first GUIs. They are present in a wide range of electronic devices including computers, graphing calculators, mobile phones, and portable media players. The user interacts with the scrollbar elements using some method of direct action, the scrollbar translates that action into scrolling commands, and the user receives feedback through a visual updating of both the scrollbar elements and the scrolled content. Although scrollbar designs differ throughout their history, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keyboard Shortcuts
In computing, a keyboard shortcut (also hotkey/hot key or key binding) is a software-based assignment of an action to one or more keys on a computer keyboard. Most Operating system, operating systems and Application software, applications come with a Table of keyboard shortcuts, default set of keyboard shortcuts, some of which may be modified by the User (computing), user in the Settings (Windows), settings. Keyboard configuration software allows users to create and assign Macro (computer science), macros to key combinations which can perform more complex sequences of actions. Some older keyboards had a physical macro key specifically for this purpose. Terminology The precise words used for these assignments and their meaning can vary depending on the context. For example, Microsoft has generally used ''keyboard shortcuts'' for Microsoft Windows, Windows and Microsoft Office since the transition to 64-bit computing, 64-bit for Windows 7. However, they used ''hot keys'' pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pinch (action)
A pinch is a grip of a flexible object in which a portion is taken between two fingers, until it hurts, or something of resemblance and squeezed so the gripped portion of the object is lifted from its normal level. By extension, that which is taken in the grip is referred to as a "pinch." When the fingers are used to perform a pinch, the action usually consists of the thumb and one other finger. The closer to the thumb the other finger is located, the stronger the pinch. Pinch of the skin The term "pinch" often refers to the action being taken on the skin. A pinch of the skin displaces the skin and blood beneath from its natural position, and may inflict a minor degree of pain, which may increase if the amount of skin being pinched is smaller, but is usually tolerable to most. Pinching the skin can result in pinch marks, a cutaneous condition, and when on the ears or in the genital region of male children may be suggestive of child abuse. Medical uses Pinching has the foll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Device
A mobile device or handheld device is a computer small enough to hold and operate in hand. Mobile devices are typically battery-powered and possess a flat-panel display and one or more built-in input devices, such as a touchscreen or keypad. Modern mobile devices often emphasize wireless networking, to both the Internet and to other devices in their vicinity, such as headsets or in-car entertainment systems, via Wi-Fi, Bluetooth, cellular networks, or near-field communication. Characteristics Device mobility can be viewed in the context of several qualities: * Physical dimensions and weight * Whether the device is mobile or some kind of host to which it is attached is mobile * What kind of host devices it can be bound with * How devices communicate with a host * When mobility occurs Strictly speaking, many so-called mobile devices are not mobile. It is the host that is mobile, i.e., a mobile human host carries a non-mobile smartphone device. An example of a true mobile co ...

Digital Zoom
Digital zoom is a method of decreasing the precise angle of view of a digital photograph or video image. It is accomplished by cropping an image down to an area with the same aspect ratio as the original, and scaling the image up to the dimensions of the original. The camera's optics are not adjusted. It is accomplished electronically, so no optical resolution is gained. Digital zooming may be enhanced by computationally expensive algorithms which sometimes involves artificial intelligence. In cameras that perform lossy compression, digital zoom is preferred to enlargement in post-processing, as the zooming may be applied before detail is lost to compression. In cameras that save in a lossless format, resizing in post-production yields results equal or superior to digital zoom. Lower-end camera phones use only digital zoom and do not have optical zoom, while many higher-end phones have additional rear cameras, including fixed telephoto lenses that allow for the simulation of ...

Disability
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be Cognitive disability, cognitive, Developmental disability, developmental, Intellectual disability, intellectual, mental disorder#Disability, mental, physical disability, physical, Sense, sensory, or a combination of multiple factors. Disabilities can be Birth defect, present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on the individual. A disability may be readily visible, or Invisible disability, invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: Disabilities have been perceived differently throughout history, through a variety of ...

Web Browser
A web browser, often shortened to browser, is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers can also display content stored locally on the user's device. Browsers are used on a range of devices, including desktops, laptops, tablets, smartphones, smartwatches and consoles. As of 2024, the most used browsers worldwide are Google Chrome (~66% market share), Safari (~16%), Edge (~6%), Firefox (~3%), Samsung Internet (~2%), and Opera (~2%). As of 2023, an estimated 5.4 billion people had used a browser. Function The purpose of a web browser is to fetch content and display it on the user's device. This process begins when the user inputs a Uniform Resource Locator (URL), such as ''https://en.wikipedia.org/'', into the browser's address bar. Virtually all URLs on the Web start with either ''http:'' or ''h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
