Graphics program - Graphics program A graphics program is a piece of computer software that enables a user to modify or view graphics files. Computer graphics can be classified into two distinct categories: raster graphics and vector graphics. Before learning about computer software that manipulates or displays these graphics types, you should be familiar with both. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that combine them in interesting and sometimes unexpected ways. Most graphics programs have the ability to import and export one or more graphics file formats. Several graphics programs support animation, or digital video. Vector graphics animation can be described as a series of mathematical transformations that are applied in sequence to one or more shapes in a.
Vector graphics - Vector graphics Vector graphics describes the use of geometrical primitives such as points, lines, curves, and polygons to represent images in computer graphics. It is used by contrast to the term raster graphics, which is the representation of images as a collection of pixels (dots). Virtually all current output devices must ultimately translate vector representations of an image to a raster format, but when working with vector graphics such a transformation is only done at the time the image is actually required and may be done completely differently depending on the device at which the rendering is to be targeted at. In the 1970's and 1980's, special vector graphics systems were available, in which the electron beam of the CRT display monitor was steered directly to trace.
Vector graphics editor - Vector graphics editor A vector graphics editor is a computer program that allows users to compose and edit vector graphics pictures interactively on the computer screen (compare with MetaPost) and save them in one of many popular vector graphics formats such as .CDR, PDF, WMF or SVG. The main difference between this sort of application and those used in Computer Assisted Drafting is that the drawings produced by a vector graphics editor are mostly decorative and are neither intended to represent a real-world structure nor to act as the blueprint for one. Computationally speaking, however, the two processes are closely related. Well-known vector graphics editors Adobe Illustrator, the de facto standard CorelDraw Macromedia FreeHand OpenOffice.org Draw {SVG output/ no SVG input yet} Free W3C Amaya can create.
Hello world program - Hello world program A "hello world" program is a computer program that simply prints out "Hello, world!". It is used in many introductory tutorials for teaching a programming language and many students use it as their first programming experience in a language. A "hello world" program is typically one of the simpler programs possible in a computer language. Some are surprisingly complex, especially in some Graphical User Interface (GUI) contexts. Some others are surprisingly simple, especially those which heavily rely on a particular shell to perform the actual output. A "hello world" program can be a useful sanity test to make sure that a language's compiler, development environment, and run-time environment are correctly installed. Configuring a complete programming tool chain from scratch to the point where even trivial.
GRASS programming language - GRASS programming language GRASS (GRAphics Symbiosis System) was a programming language created to script visual animations in 2D. GRASS was similar to the BASIC programming language in syntax, but added numerous instructions for specifying 2D object animation, including scaling, translation, rotation and color changes over time. It quickly became a hit with the artistic community who were experimenting with the new medium of computer graphics, and will remain most famous for its use by Larry Cuba to create the original "attacking the death star will not be easy" animation in Star Wars. History The original version of GRASS was developed by Tom DeFanti for his 1974 Ohio State University Ph.D. thesis. It was developed on a PDP-11/45 driving a Vector General 3DR display, and as the name implies, this was.
Applesoft BASIC programming language - Atomic strings. A string is no longer an array of characters (like in C); it is instead a garbage-collected object (like in Scheme and Java). This allows for string arrays; DIM A$(10) got you a vector of ten string variables. Multidimensional arrays. Single-precision floating point variables with an 8-bit exponent and a 31-bit significand. Along with this came a trigonometry library. High-resolution graphics. CHR$, ASC, STR$, and VAL functions for converting between string and numeric types No more writing LET Why weren't many action games written in Applesoft BASIC? Integer variables had to be converted to reals before math could be performed on them; they were then converted back to integers. Slowly. Microsoft forgot to special case this. So-called shape tables are a slow alternative to bitmaps. No provision for mixing.
Application Programming Interface - is often called the implementation of that API. For example, one may look at the task of writing "Hello World" on a screen at increasing levels of abstraction: Do it all yourself: Draw, on graph paper, the shapes of the letters H, e, l, l, o, W, o, r, l, d. Work out a matrix of black and white squares that look like those letters. Devise a way to program the CPU to put this matrix into the display adapter's frame buffer. Set the graphics card up to scan its frame buffer to generate the correct signal. Use an operating system to do some of the work: Load a data structure called a "font" provided with the operating system. Have the operating system display a blank window. Have the operating system.
BASIC Programming - console in 1979. One of only a few non-gaming cartridges, this program allowed consumers to create some simple programs using its own unique programming language. The BASIC Programming display is divided into six regions: "Program" - where instructions are written (maximum of nine lines of code). "Stack" - shows temporary results of what your program does. "Variables" - displays the values of any variables your program is using. "Output" - displays any output values your program is creating. "Status" - displays the amount of available memory remaining "Graphics" - contains two colored squares that can be manipulated by your program. Basic Programming\ requires two Atari keyboard controllers, and came with special overlays to show how to type the different commands and letters. Programmer: Warren Robinett.
Bitmap graphics editor - Bitmap graphics editor A bitmap graphics editor is a computer program that allows users to compose and edit pictures interactively on the computer screen and save them in one of many popular "bitmap" or "raster" formats such as TIFF, JPEG, PNG and GIF. Bitmap graphics editors: Photoshop Painter Paint Shop Pro Photopaint The GIMP CodedColor Historical: Deluxe Paint Personal Paint See Also Wikipedia:Basic bitmap image editing for a tutorial on using graphics editors..
Scalable Vector Graphics - Scalable Vector Graphics Scalable Vector Graphics (SVG) is a language for describing two-dimensional static and animated vector graphics in XML. SVG became a W3C recommendation in September 2001. SVG was developed in a long process after Macromedia and Microsoft introduced VML whereas Adobe and Sun submitted a competing format known as PGML. SVG is natively supported in the Amaya web browser. In other ones, a plugin, like Adobe SVG Viewer or Corel SVG Viewer, is needed to see SVG images, but they can be displayed by external editors and viewers. Mozilla now supports parts of the W3C SVG Standard, but much is still unsupported. From the W3C Overview of SVG: SVG allows three types of graphic objects: vector graphic shapes (e.g. paths consisting of straight lines and curves).
ScriptBasic programming language - scripting language variant of BASIC. The source of the compiler is available as a C program under the LGPL license. The compiler generates intermediary code which is then interpreted by a runtime environment. ScriptBasic is available for Windows and Unix and may be embedded in other programs as well. It can create standalone executable files. A runtime library is linked into the executable. It is available in precompiled binaries (setup.exe under Windows and uninstall also supported), dpkg and rpm for Linux and in source code form. The language, the interpreter is fully documented in the Users' Guide available in text, HTML, CHM, TeX, texi and PDF formats. ScriptBasic has been developed since 1999 and has reached a fairly matured state in terms of functions and stability. The precompiled version available for.
Sketch vector graphics editor - Sketch vector graphics editor Sketch is a vector-based illustration computer program for various UNIX platforms. It is written in C and uses the GTK+ libraries to provide object and GUI services. Sketch is open source and licenced under the GNU Library General Public Licence (LGPL).

Presentation program - Presentation program A presentation program is a computer software package used to give presentations, normally in the form of a "slide show". They typically include three major functions, the slide show system to display content in a linear fashion, an editor that allows text to be moved around en-mass from slide to slide, and a graphics system for quickly drawing "business graphics" (charts and graphs). The most common example of a presentation program today is Microsoft PowerPoint, originally a 3rd party application for the Macintosh that was purchased in the 1980s. PowerPoint is considered by many to be the worse of all presentation programs, with Aldus Persuasion often being used as the benchmark. However Microsoft's dominant position in the "office suite" market has pushed all other players.
Lua programming language - glue language with extensible semantics as a primary goal. Lua was created by the Computer Graphics Technology Group of the Pontifical Catholic University of Rio de Janeiro in Brazil in 1993. It is released as free software, versions before 5.0 were released under BSD-like license terms, which are non-copyleft. From version 5.0 Lua uses the MIT License. Lua has been used in many commercial applications (e.g., in LucasArts' Escape from Monkey Island adventure game and robot control software). Its closest relative in the family of programming languages is perhaps the Icon programming language, although it could also be compared to Python in its emphasis on ease of use for non-programmers. Lua has a compact design, and this is evident from the fact that it supports only one data structure, the table..

Koala Pad - the C64 courtesy Randy Byrnes The Koala Pad is a graphics tablet which was produced for most of the early 8bit machines, including the Apple II, TRS-80 Color Computer, Commodore 64 and Atari 8-bit family. Originally designed by Dr. David Thornburg as a low-cost drawing tool for schools, the Koala Pad was very popular with home users as well. The pad itself was 4 inches square, mounted on a slightly inclined base with the back of the pad higher than the front. At the top, "behind" the pad, were two buttons. The pad hooked into the computer using analog joystick (or "paddle") inputs, which meant that it had fairly low resolution and tended to jostle the cursor as it was moved. The tablet shipped with a simple graphics program, Koala Painter.
Video coding - to as multimedia. Modern video coding standards even include other multimedia data such as synthetic computer graphics, text and meta information for searching/browsing and digital rights management. They also often provide mechanisms for user interaction. However, the most intensive parts of video data in terms of data size (memory demand, transmission bandwidth) remain (visual) video and audio data. These parts have to be compressed. Unfortunately, this can hardly be done without loss of quality (lossy compression). There are two special research areas that deal with multimedia compression: video compression and audio compression. Video coding has two distinct goals: storing and transmission of video data. These two goals have much in common. Therefore, video file formats usually have the same structure as streaming video formats with just a little header information added..
Videotex - which was a one-way service carried in the existing TV signal, Viewdata was a two-way system using telephones. Since the Post Office owned the telephones, this was considered to be an excellent way to drive more customers to use the phones. Not to be outdone by the BBC, they also announced their service, under the name Prestel. ITV soon joined the frey with a Ceefax-clone known as ORACLE. In 1974 all of the services sat down and created a standard for displaying the information. The display would be a simple 40x24 grid of text, with some graphics characters for constructing simple graphics. This standard was called CEPT1. The standard did not define the delivery system, so both Viewdata-like and Teledata-like services could at least share the TV-side hardware (which at that.

Visual Basic .NET - is extensive documentation that covers changes in the syntax (rules of the language), the changes in debugging applications, deployment and terminology. Controversy concerning VB.NET Visual Basic .NET could be said to represent a bold and aggressive business move by Microsoft, because it discontinues a large number of capacities that were present in earlier versions of Visual Basic (which are now no longer sold); however, to balance the argument, VB.NET is a much more powerful language in some respects, incorporating modern programming paradigms. Indeed, some experts in Visual Basic .NET have characterized it as an entirely new programming language. Visual Basic programs that relied heavily on such things as databases and graphics will, in general, have difficulty in migrating to VB.NET, while programs such as mathematical programs that are mainly algorithm based,.
