Vector-based Graphical User Interface
A vector-based graphical user interface is a mostly conceptual type of graphical user interface where elements are drawn using vector information instead of raster information. Pros and cons The benefits of a completely vector-based graphical user interface would include: :*more efficient, independent scalability; The resolution (measured in dots per inch or DPI) could be set higher or lower than 1px:1px without causing pixelation, enabling better use of high resolution monitors. Cons might include: :*Difficulty integrating raster-based applications. With some effort, this could be accomplished by texturing the entire raster-based application to a vector-based plane (though the disadvantages of raster-based graphics would still stand). :*Slower rendering, greater system requirements. Because today's monitors display only raster-based information, the vector information would have to be rasterized (and optionally anti-aliased) before appearing. Usage in 3D graphical user inte ...

Graphical User Interface
A graphical user interface, or GUI, is a form of user interface that allows user (computing), users to human–computer interaction, interact with electronic devices through Graphics, graphical icon (computing), icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based user interface, text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation interface, direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and Distributed control system, industrial controls. The term ''GUI'' tends not to be applied to other lower-displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Zooming User Interface
In computing, a zooming user interface or zoomable user interface (ZUI, pronounced zoo-ee) is a type of graphical user interface (GUI) where users can change the scale of the viewed area in order to see more detail or less, and browse through different documents. Information elements appear directly on an infinite virtual desktop (usually created using vector graphics), instead of in windows. Users can pan across the virtual surface in two dimensions and zoom into objects of interest. For example, as you zoom into a text object it may be represented as a small dot, then a thumbnail of a page of text, then a full-sized page and finally a magnified view of the page. ZUIs use zooming as the main metaphor for browsing through hyperlinked or multivariate information. Objects present inside a zoomed page can in turn be zoomed themselves to reveal further detail, allowing for recursive nesting and an arbitrary level of zoom. When the level of detail present in the resized obje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha Channel
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated '' matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cairo (Graphics)
Cairo (stylized as cairo) is an Open-source software, open-source graphics library that provides a vector graphics-based, device-independent Application programming interface, API for software developers. It provides primitives for Plane (mathematics), two-dimensional drawing across a number of different front and back ends, backends. Cairo uses hardware acceleration when available.

Workbench (AmigaOS)
Workbench is the desktop environment and graphical spatial file manager, file manager of AmigaOS developed by Commodore International for their Amiga line of computers. Workbench provides the user with a graphical interface to work with file systems and launch applications. It uses a workbench metaphor (in place of the more common desktop metaphor) for representing file system organisation. "Workbench" was also the name originally given to the entire Amiga operating system up until version 3.1. From release 3.5 the operating system was renamed "AmigaOS" and subsequently "Workbench" refers to the graphical front end only. Overview The Amiga Workbench uses the metaphor of a workbench (i.e. a workbench for manual labor), rather than the now-standard desktop metaphor, for representing file system organization. The desktop itself is called ''Workbench'' and uses the following representations: ''drawers'' (instead of folders) for directories, ''tools'' for executable programs, ''p ...

AmigaOS
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola Motorola 68000 family, 68000 series of 16-bit and 32-bit microprocessors. Later versions, after Commodore's demise, were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent AmigaOS 4-release. AmigaOS is a single-user operating system based on a preemptive multitasking kernel (operating system), kernel, called Exec (Amiga), Exec. It includes an abstraction of the Amiga's hardware, a disk operating system called ''AmigaDOS'', a windowing system Application programming interface, API called Intuition (Amiga), ''Intuition'', and a desktop environment and file manager called Workbench (AmigaOS), ''Workbenc ...

Desktop Window Manager
Desktop Window Manager (DWM, previously Desktop Compositing Engine or DCE in builds of pre-reset Windows Longhorn) is the compositing window manager in Microsoft Windows since Windows Vista that enables the use of hardware acceleration to render the graphical user interface of Windows. It was originally created to enable portions of the new "Windows Aero" user experience, which allowed for effects such as transparency, 3D window switching and more. It is also included with Windows Server 2008, but requires the "Desktop Experience" feature and compatible graphics drivers to be installed. Architecture The Desktop Window Manager is a compositing window manager, meaning that each program has a buffer that it writes data to; DWM then Compositing, composites each program's buffer into a final image. By comparison, the stacking window manager in Windows XP and earlier (and also Windows Vista and Windows 7 with Windows Aero disabled) comprises a single display buffer to which all progra ...

Dots Per Inch
Dots per inch (DPI, or dpiThe acronym appears in sources as either "DPI" or lowercase "dpi". See "Print Resolution Understanding 4-bit depth – Xerox" (PDF). Xerox.com. September 2012.) is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of . Similarly, dots per millimetre (d/mm or dpmm) refers to the number of individual dots that can be placed within a line of . DPI measurement in printing DPI is used to describe the resolution number of dots per inch in a digital print and the printing resolution of a hard copy print dot gain, which is the increase in the size of the halftone dots during printing. This is caused by the spreading of ink on the surface of the media. Up to a point, printers with higher DPI produce clearer and more detailed output. A printer does not necessarily have a single DPI measurement; it is dependent on print mode, which is usually influenced b ...

Windows XP
Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct successor to Windows 2000 for high-end and business users and Windows Me for home users. Development of Windows XP began in the late 1990s under the codename "Windows Neptune, Neptune", built on the Architecture of Windows NT#Kernel, Windows NT kernel and explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of Windows not based on the Windows 95 kernel or MS-DOS. Upon its release, Windows XP received critical acclaim, noting increased performance and stability (especially compared to Wi ...

Windows Presentation Foundation
Windows Presentation Foundation (WPF) is a free and open-source user interface framework for Windows-based desktop applications. WPF applications are based in .NET, and are primarily developed using C# and XAML. Originally developed by Microsoft, WPF was initially released as part of .NET Framework 3.0 in 2006. In 2018, Microsoft released WPF as open source under the MIT License. WPF's design and its layout language XAML have been adopted by multiple other UI frameworks, such as UWP, .NET MAUI, and Avalonia. Overview WPF employs XAML, an XML-based language, to define and link various interface elements, and uses C# to define program behavior. WPF applications are deployed as standalone desktop programs. WPF supports a number of common user interface elements, such as 2D/3D rendering, fixed and adaptive documents, typography, vector graphics, runtime animation, and pre-rendered media. These elements can then be linked and manipulated based on various events, user interact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
