Wayland (display Server)
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a ''Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a modern, secure simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called ''Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graphics ...

X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a ...

Fontconfig
Fontconfig (or fontconfig) is a free software program library designed to provide configuration, enumeration and substitution of fonts to other programs. Fontconfig was originally written and maintained by Keith Packard, and is currently maintained by Behdad Esfahbod. Fontconfig is typically used on graphical Linux (and other Unix-like) desktops, such as Xorg and Wayland, where it remains an important part of handling fonts. However, it is also sometimes used on other platforms, notably including Windows versions of software that use Pango for laying out and rendering text, such as GIMP. Usage End-users can use fontconfig, directly or indirectly, to customize and configure fonts on the system. Applications can use fontconfig in two ways: # by querying it for the available fonts on the system, or # by querying it for a font matching certain parameters (comprising a ''pattern'') as closely as possible. To perform font matching, fontconfig stores typesetting information about all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cairo (graphics)
Cairo (stylized as cairo) is an open-source graphics library that provides a vector graphics-based, device-independent API for software developers. It provides primitives for two-dimensional drawing across a number of different back ends. Cairo uses hardware acceleration when available. Software architecture Language bindings A library written in one programming language may be used in another language if bindings are written; Cairo has a range of bindings for various languages including C++, C# and other CLI languages, Delphi, Eiffel, Factor, Harbour, Haskell, Julia, Lua, Perl, PHP, Python, Ruby, Rust, Scheme, Smalltalk and several others like Gambas (Visual Basic like). Toolkit bindings Since Cairo is only a drawing library, it can be quite useful to integrate it with a graphical user interface toolkit. * FLTK has full Cairo support (through --enable-cairo compile switch). * GTK began in 2005, with version 2.8, to use Cairo to render the majority of its gra ...

Mode-setting
Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller by using VESA BIOS Extensions or UEFI Graphics extensions (on more modern computers). The display mode is set by the kernel. In ''user-space mode-setting'' (UMS), the display mode is set by a user-space process. Kernel mode-setting is more flexible and allows displaying of an error in the case of a fatal system error in the kernel, even when using a user-space display server. User-space mode setting would require superuser privileges for direct hardware access, so kernel-based mode setting shuns such requirement for the user-space graphics server. Implementation Microsoft Windows Microsoft Windows versions that are NT-based use kernel mode setting. The kernel error display made possible by kernel mode setting is officially called "bug check", but more commonly known as the Blue Screen of Death. Linux The Linux ...

Xdmx
In computing, the X Window System (commonly: X11, or X) is a Network transparency, network-transparent windowing system for raster graphics, bitmap displays. This article details the protocols and technical structure of X11. Client–server model and network transparency X uses a client–server model. An ''X server'' program runs on a computer with a graphical display and communicates with various ''client programs''. The X server acts as a go-between for the user and the client programs, accepting requests on TCP port 6000 for graphical output (windows) from the client programs and displaying them to the user (display), and receiving user input (keyboard, mouse) and transmitting it to the client programs. In X, the server runs on the user's computer, while the clients may run on remote machines. This terminology reverses the common notion of client–server systems, where the ''client'' normally runs on the user's local computer and the server runs on the remote computer. The ...

Direct Rendering Manager
The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards. DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display. DRM was first developed as the kernel-space component of the X Server Direct Rendering Infrastructure, but since then it has been used by other graphic stack alternatives such as Wayland. User-space programs can use the DRM API to command the GPU to do hardware-accelerated 3D rendering and video decoding, as well as GPGPU computing. Overview The Linux kernel already had an API called fbdev, used to manage the framebuffer of a graphics adapter, but it couldn't be used to handle the needs of modern 3D-accelerated GPU-based video hardware. These devices usually require setting and managing a command queue in their own memory to dispatch commands to the GPU and also require management ...

Direct Rendering Infrastructure
The Direct Rendering Infrastructure (DRI) is the framework comprising the modern Linux graphics stack which allows unprivileged user-space programs to issue commands to graphics hardware without conflicting with other programs. The main use of DRI is to provide hardware acceleration for the Mesa implementation of OpenGL. DRI has also been adapted to provide OpenGL acceleration on a framebuffer console without a display server running. DRI implementation is scattered through the X Server and its associated client libraries, Mesa 3D and the Direct Rendering Manager kernel subsystem. All of its source code is free software. Overview In the classic X Window System architecture the X Server is the only process with exclusive access to the graphics hardware, and therefore the one which does the actual rendering on the framebuffer. All that X clients do is communicate with the X Server to dispatch rendering commands. Those commands are hardware independent, meaning that the ...

Rendering (computer Graphics)
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a ''scene file'' containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output. Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. It is the last major step in the gr ...
