Haiku Vector Icon Format
Haiku Vector Icon Format (HVIF) is a vector storage format designed to store icons, specifically for Haiku. History Haiku developers commonly agreed that Haiku could not be released with original BeOS R5 icons. Since Haiku needed its own artwork anyway, it was thought that icons could switch to vectors graphics from traditional BeOS bitmaps. In July 2006 Haiku developer Stephan Aßmus introduced Icon-O-Matic, the icon editor of Haiku, and a storage format with a rendering engine based on Anti-Grain Geometry. After a few days of discussion, Aßmus announced a contest to determine an icon theme for Haiku. He stated that there was no guideline that had to be followed and suggested 1 September as deadline. 16 icon sets were rated in the contest, and Aßmus' icon set "Stippi" received the award. In early November it was also announced that Stephan Aßmus implemented vector icons in OpenTracker. HVIF icons of Stippi set are used in current Haiku releases and builds. Features ...

Haiku (operating System)
Haiku is a free and open-source operating system application level compatible with the discontinued BeOS. Its development began in 2001, and the operating system became self-hosting in 2008. The first alpha release was made in September 2009, and the last was November 2012; the first beta was released in September 2018, followed by beta 2 in June 2020, beta 3 in July 2021. The fourth beta was released on December 23, 2022, still keeping BeOS 5 compatibility in its x86 32-bit images, with much increased number of modern drivers, GTK3 apps and Wine ported, as well as Xlib (X11) and Wayland compatibility layers. Haiku is supported by Haiku, Inc., a non-profit organization based in Rochester, New York, United States, founded in 2003 by former project leader Michael Phipps. In the recent release cycle, Haiku, Inc. employed a developer. History Haiku began as the ''OpenBeOS'' project in 2001, the same year that Be, Inc. was bought by Palm, Inc. and BeOS development was disco ...

Vector Graphics
Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing ''hardware'', vector ''data models'' and file formats, as well as the ''software'' based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continues to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D ren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BeOS R5
BeOS R5 is the final version of BeOS from Be Inc. It was released in March 2000, and came in two varieties: Professional and Personal. R5 was the 4th major release of BeOS for a public audience, and the 6th since it left developer-only stages. It changed only slightly from the previous release, BeOS R4.5, and was even seeded to developers as "R4.6". Improved POSIX compliance, particularly in the area of networking, was provided. The OS in general was moved towards the new modular media kit over the former audio-only sound subsystem. For end-users, new logos and some new icons were the only major differences. R5 was the first release of BeOS for x86 to have a freely downloadable version which could be fully installed on a user's hard drive; previous versions had a free Live CD download, which could not be installed. R5 was also to be the last version to support the PowerPC architecture which BeOS had originated on, including the company's own BeBox hardware. According to B ...

Anti-Grain Geometry
Anti-Grain Geometry (AGG) is a 2D rendering graphics library written in C++. It features anti-aliasing and sub-pixel resolution. It is not a graphics library, per se, but rather a framework to build a graphics library upon. The library is operating system independent and renders to an abstract memory object. It comes with examples interfaced to the X Window System, Microsoft Windows, Mac OS X, AmigaOS, BeOS, SDL. The examples also include an SVG viewer. The design of AGG uses C++ templates only at a very high level, rather than extensively, to achieve the flexibility to plug custom classes into the rendering pipeline, without requiring a rigid class hierarchy, and allows the compiler to inline many of the method calls for high performance. For a library of its complexity, it is remarkably lightweight: it has no dependencies above the standard C++ libraries and it avoids the C++ STL in the implementation of the basic algorithms. The implicit interfaces are not well documented, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenTracker
Opentracker is a free (licensed as beerware) BitTorrent peer tracker software (a special kind of HTTP or UDP server software) that is designed to be fast and to have a low consumption of system resources. Features Several instances of opentracker may be run in a cluster, with all of them synchronizing with each other. Besides the Hypertext Transfer Protocol (HTTP) opentracker may also be connected to via User Datagram Protocol (UDP), which creates less than half of the tracker traffic HTTP creates. It supports IPv6, gzip compression of full scrapes, and blacklists of torrents. Because there have already been cases of people being accused of copyright violation by the fact that their IP address was listed on a BitTorrent tracker, opentracker may mix in random IP address numbers for the purpose of plausible deniability. Technology It runs completely in RAM, accounting for much of its speed advantage over other tracker software. It is written in C and based on the lib ...

Bitmap
In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array or bitmap index. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each one may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the array of pixels which constitute a digital graphic output device (a screen or monitor). In some contexts, the term ''bitmap'' implies one bit per pixel, whereas ''pixmap'' is used for images with multiple bits per pixel. A bitmap is a type of memory organization or image file format used to store digital images. The term ''bitmap'' comes from the computer programming terminology, meaning just a ''map of bits'', a spatially mapped array of bits. Now, along with ''pixmap'', it commonly refers to the similar concept of a spatially mapped array of pixels. Raster i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inode
The inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block locations of the object's data. File-system object attributes may include metadata (times of last change, access, modification), as well as owner and permission data. A directory is a list of inodes with their assigned names. The list includes an entry for itself, its parent, and each of its children. Etymology There has been uncertainty on the Linux kernel mailing list about the reason for the "i" in "inode". In 2002, the question was brought to Unix pioneer Dennis Ritchie, who replied: A 1978 paper by Ritchie and Ken Thompson bolsters the notion of "index" being the etymological origin of inodes. They wrote: Additionally, Maurice J. Bach wrote that an inode "is a contraction of the term index node and is commonly used in literature on the UNIX system". Details A file system relies on d ...

Haiku Tracker
Haiku Tracker is a graphical user interface for managing files of the Haiku operating system. It is somewhat similar to Finder on Mac OS 9 and Mac OS X. Haiku Tracker is based on OpenTracker which in turn is based on Tracker found in the BeOS. History The original Tracker was created by Be Inc., as part of BeOS, but was opensourced in late 2000. The project was managed by Be until its close-down in late 2001, when it moved to SourceForge under the guidance of Axel Dörfler, the chief non-Be contributor. It is under the OpenTracker License, which is a barely modified BSD license that allows the use of the Be trademark Tracker to be used. Deskbar The Deskbar is a taskbar that is by default placed in the upper right corner of the screen of the Haiku operating system. It is composed of the deskbar menu, the tray (clock information panel) and the list of running programs. The Tracker is always shown on the top of the list of running programs.

Computer File Formats
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations ( computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics 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 The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
