About X toolkit compiler intrinsics Intrinsic function Telecom s XT Mobile Network XT Mobile Network X Toolkit Intrinsics also known as Xt , for X toolkit is a library computer science library used in the X Window System . More precisely, it is a library that uses the low level Xlib library and provides a friendly object oriented looking API to develop X11 software with graphical widgets. It can be used in the C programming language C or C languages. Image X client libraries.svg frame Xt and related libraries The low level Xlib library provides functions for interacting with an X11 Server computing server , but does not provide any function for implementing the graphical objects used in GUI s, such as buttons, menus, etc. Such objects are called Widget computing widgets . The Xt library provides support for creating and using widget types, but does not provide any specific widget. Specific widgets are implemented by other libraries using Xt, such as Xaw and Motif widget toolkit Motif . A programmer can for example use the Xt library to create and use a new widget type such as a two side button. Since applications typically require a number of standard widgets such as buttons, menus, etc., they usually rely on a library such as Xaw and Motif widget toolkit Motif that provides such widgets, rather than implementing them directly using Xt. Most modern toolkits such as FLTK , GTK GTK , and Qt toolkit Qt do not use the Xt library, preferring to use Xlib directly.

For color recovery of archived television broadcasts, see Colour recovery . Color recovery is a technique used in Hewlett Packard s older workstation graphics devices to produce a near 24 bit color look from an 8 bit framebuffer. Color recovery does rely on software support which is provided by libraries such as PHIGS , PEXLib , Starbase and even Xlib although Xlib does not enable it by default. When using Color Recovery the data is sent to the driver as an 24 bit image. The driver will then dither the data in most cases this can be done by the graphics hardware for maximum performance which is stored in the framebuffer as an 8 bit image. On displaying that 8 bit image data, HP s color recovery technology produces in real time an approximation of the original 24 bit image based on the hints provided by the dithered data. The result is significantly better looking than dithering alone. According to the article in HP s journal, the color recovery could achieve up to 23 bits of color accuracy.

Tgif pronounced t g i f is an Xlib based interactive 2 D drawing tool under X11 for Unix , available on Linux and most Unix and Unix like platforms. It was developed since 1990 and is free software released under the QPL license. Tgif is one of the few free software free drawing programs that has, as well as a ruler, a usable Grid spatial index grid . Quirks Because Tgif was developed long before a standard way for drawing programs to work, one might find it unfamiliar to use in a number of ways Although it might mention point sizes, it uses a unit that is 1 128 of an inch for point sizes. There is an option to display font sizes in points, the sizes are still subject to rounding to the nearest 1 128 . Unlike modern drawing programs, Tgif uses spline curve s instead of B zier curve s. Colour is not selected from a colour wheel or through controls that allows one to adjust colour values instead, there is a named list with a short list of colours. To use a colour that is not in the list, one needs to add the colour to the list. This list gets saved with the drawing. Fonts that can be used are listed in a configuration file. To use fonts that are not on the list, one has to change the configuration file. Only fonts in the ISO 8859 1 encoding, square CJK fonts, and Symbol typeface symbol or dingbat fonts can be used. Rescaling can lead to ugly artifacts, which is probably due to the use of integer coordinates and roundoff errors. In addition, because Tgif uses Xlib, which predated modern Unicode support, Tgif does not support Unicode in any form. The Tgif file format Tgif saves its drawings in a Prolog based plain text file format. Partly because it is based on Prolog, there is little support from other programs for reading the Tgif file format. Fonts are represented as PostScript font names. Originally, it was possible to print Tgif drawings in batch mode without using a X11 X display however, this changed somewhere in the 4.1 versions. Currently, printing drawings requires ... more details

About the computer program the all wheel drive system Saab XWD Nofootnotes date June 2008 lowercase xwd In the X Window System , xwd is a Computer program program for capturing the content of the screen or of a window and saving it into a Computer file file . xwd can be run in two ways if user specifies the whole screen or the name or identifier of a window as an argument, the program captures the content of the window otherwise, it changes the shape of the cursor and waits for the user to click in a window, whose content is then captured. At the X Window core protocol level, xwd uses the fact that any X client can request the content of an arbitrary window, including ones it did not create, using the code GetImage code request this is done by the code XGetImage code function in the Xlib library . The content of the whole screen is obtained by requesting the content of the root window . The file generated by xwd can then be read by various other X utilities such as xwud , xv , and the GIMP , or converted to other formats the netpbm suite allows a useful Unix pipe pipeline to be constructed xwd xwdtopnm pnmtopng Screenshot.png The dumps are larger in size than files in most image file format s not only compressed formats such as Portable Network Graphics PNG , but also uncompressed bitmap formats like BMP file format BMP .

The MIT Shared Memory Extension or MIT SHM is a X Window System extension for exchange of image data between client and server using shared memory . The basic capability provided is that of shared memory XImages. This is essentially a version of the ximage interface where the actual image data is stored in a SysV shared memory segment, and thus need not be transferred across the Unix domain socket socket to the X server. For large images, use of this facility can result in some real performance increases. Additionally, some implementations provide shared memory pixmaps. These are 2 dimensional arrays of pixels in a format specified by the X server, where the image data is stored in the shared memory segment. Through use of shared memory pixmaps, it is possible to change the contents of these pixmaps without using any Xlib routines at all. Shared memory pixmaps can only be supported when the X server can use regular virtual memory for pixmap data if the pixmaps are stored in the on board memory of graphics hardware, an application will not be able to share them with the server.

MiniGLX is a specification for an application programming interface which facilitates OpenGL rendering on systems without windowing system s, e.g. Linux without an X Window System or embedded systems without a windowing system. The interface is a subset of the GLX interface, plus a minimal set of Xlib like functions. Programs written for Mini GLX can run unchanged on systems with the X Window System and the GLX extension. The intention is to allow flexibility for prototyping and testing. MiniGLX is currently implemented within the Mesa 3D project that provides a means to use the Direct Rendering Infrastructure when the X Window System is not used. In essence it provides functions that mimic those of X, so that programs written using MiniGLX should be compilable as X Window programs. MiniGLX renders directly to the framebuffer device or through accelerated DRI drivers. MiniGLX allows only one window which fills the whole framebuffer to exist. If the existing source code were extended, MiniGLX could be used by GPGPU applications, using the power of graphics card processors for general, non graphical tasks, as long as no other driver uses the graphics card . NVIDIA has already integrated support for using the graphics processing unit on NVidia cards for application programming into its proprietary software proprietary 3D graphic driver.

Image vtwm.jpg thumb A screen shot of Vtwm in Linux From Scratch LFS running mrxvt , xmms and the Opera web browser Vtwm the Virtual Tabbed Window Manager is an X window manager that was developed from the twm codebase. The first release was in 1990, and it is very much an old school window manager. It added features like X Pixmap xpm icons, autoraising of windows, and a virtual desktop the latter feature is from where the program takes its name. Later additions include playing sounds in response to window manager events, and Motif widget toolkit Motif style window decorations in place of the flat, 2D titlebars commonly associated with twm. Vtwm was one of the first window managers to have an icon manager, a box of click able windows which mapped to the application windows currently on the desktop. Clicking the entry in the icon manager iconizes deiconizes the associated application. This behavior is common today in taskbar s in many operating systems. Features A stacking window manager Written in C Uses the xlib toolkit opensource and freely available No menubar Lightweight Has few dependencies Support for multiple desktop s Other features of twm, including shaped window titlebars, are faithfully incorporated into vtwm. The focus of vtwm is to maintain simplicity and compatibility.

A re parenting window manager is an X Window System window manager that adopts all other windows. In the X Window System , every window has a parent window, which may be either the root window or another window. Windows that are children of the root window are called top level windows . When a top level window is created, a re parenting window manager changes its parent to be a new window created on purpose. This allows the window manager to decorate the windows with window decoration s and title bar s as well as allows advanced control over the windows operation required, for example, by virtual window manager s. Technically, a reparenting window manager registers with the X server to be notified when a top level window is mapped attempts to become visible . When such an Event driven programming event is generated, the window manager creates a frame window , and in most cases also a title bar window. The frame window then becomes the parent of both the main window and the title bar window. Other forms of decoration, such as buttons, window title, etc., may also be created these would normally be parented by the title bar window. ref http static.cray cyber.org Documentation NEC SX R10 1 G1AH04E G1AE02E CHAP10.HTML Xlib Programming Manual Chapter 10 Bot generated title ref Virtually all modern window managers are re parenting, although earlier window managers, such as the UWM computing uwm window manager, were not.

Unreferenced stub auto yes date December 2009 Pseudo transparency is a term used for X Window System clients that simulate the appearance of translucency or transparency optics transparency by manipulating the same pixmap that has been drawn on the root window computing window , or by instructing the X Server that the Background Pixmap should be inherited from the window s parent. Purpose Traditionally, the X Window System has lagged behind other windowing systems in adding purely eye candy or aesthetic features, such as window translucency . This has encouraged X client client Software developer developer s to develop Hack technology slang hacks cunning workarounds to overcome this limitation. This pseudo transparency, so called as the background pixmap of the root window is visible analogous to computer wallpaper desktop wallpaper rather than any obscured windows, allows users to make windows look less imposing such as Terminal emulator s, which usually comprise large chunks of text , and to integrate the appearance of windows with their desktop themes. Implementation There are three common methods for achieving pseudo transparency using Xlib , each with its own advantages and drawbacks. Parental relative The parental relative method uses code XSetWindowBackgroundPixmap code to inherit the parent window s background image. Unfortunately, using this method, the X server permits very few operations to be performed on the background pixmap such as XOR , preventing clients from implementing any sort of advanced image filtering. XROOTPMAP ID and ESETROOT PMAP ID properties These properties are used to inform the window where it can find the pixmap used on the root window. Using this information, a client can paint a section of the image corresponding to the size and position of the window onto its background, achieving the effect of transparency. This method uses the most Computer storage memory , but has the advantage of allowing clients to perform any operation, such ... more details
