  • Release Notes for X11R6.8.2 the X.Orgfoundation the Xfree86 Project, Inc
    Release Notes for X11R6.8.2 The X.OrgFoundation The XFree86 Project, Inc. 9February 2005 Abstract These release notes contains information about features and their status in the X.Org Foundation X11R6.8.2 release. It is based on the XFree86 4.4RC2 RELNOTES docu- ment published by The XFree86™ Project, Inc. Thereare significant updates and dif- ferences in the X.Orgrelease as noted below. 1. Introduction to the X11R6.8.2 Release The release numbering is based on the original MIT X numbering system. X11refers to the ver- sion of the network protocol that the X Window system is based on: Version 11was first released in 1988 and has been stable for 15 years, with only upwardcompatible additions to the coreX protocol, a recordofstability envied in computing. Formal releases of X started with X version 9 from MIT;the first commercial X products werebased on X version 10. The MIT X Consortium and its successors, the X Consortium, the Open Group X Project Team, and the X.OrgGroup released versions X11R3 through X11R6.6, beforethe founding of the X.OrgFoundation. Therewill be futuremaintenance releases in the X11R6.8.x series. However,efforts arewell underway to split the X distribution into its modular components to allow for easier maintenance and independent updates. We expect a transitional period while both X11R6.8 releases arebeing fielded and the modular release completed and deployed while both will be available as different consumers of X technology have different constraints on deployment. Wehave not yet decided how the modular X releases will be numbered. We encourage you to submit bug fixes and enhancements to bugzilla.freedesktop.orgusing the xorgproduct, and discussions on this server take place on <[email protected]>.

  • Optimization of Fontconfig Library Optimization of Fontconfig Library
    Michal Srb OPTIMIZATION OF FONTCONFIG LIBRARY OPTIMIZATION OF FONTCONFIG LIBRARY Michal Srb Bachelor's Thesis Spring 2017 Information Technology Oulu University of Applied Sciences ABSTRACT Oulu University of Applied Sciences Degree Programme in Information Technology, Internet Services Author: Michal Srb Title of the bachelor’s thesis: Optimization of Fontconfig Library Supervisor: Teemu Korpela Term and year of completion: Spring 2017 Number of pages: 39 + 1 appendix Fontconfig is a library that manages a database of fonts on Linux systems. The aim of this Bachelor's thesis was to explore options for making it respond faster to application's queries. The library was identified as a bottleneck during the startup of graphical applications. The typical usage of the library by applications was analyzed and a set of standalone benchmarks were created. The library was profiled to identify hot spots and multiple optimizations were applied to it. It was determined that to achieve an optimal performance, a complete rewrite would be necessary. However, that could not be done while staying backward compatible. Nevertheless, the optimizations applied to the existing fontconfig yielded significant performance improvements, up to 98% speedups in benchmarks based on the real-world usage. Keywords: fontconfig, optimization, benchmarking, profiling 3 CONTENTS 1 INTRODUCTION 6 2 BACKGROUND 7 1.1 Motivation 7 1.2 Fontconfig 8 1.2.1 Function 9 1.2.2 Configuration 11 2 ANALYSIS 12 2.1 Main entry functions 12 2.1.1 FcFontMatch 12 2.1.2 FcFontSort 14 2.1.3

  • Gstreamer SDK
    GStreamer SDK Andoni Morales Alastruey (ylatuya) GStreamer Conference, 27th of August 2012 - San Diego The GStreamer SDK is a joint initiative from Fluendo and Collabora to provide a stable and tested distribution of GStreamer for the most common platforms (Linux, Windows and OS X). ˆ The first release of the SDK, Amazon 2012.5, was done the end of May. ˆ A new bugfix release for Amazon is scheduled within the next weeks. ˆ The next release will be named Brahmputra, with support for Android. Topics: ˆ Goals of the SDK ˆ SDK's components ˆ Developments done for the SDK ˆ Building the SDK ˆ Packaging the SDK ˆ Integration with the native OS development tools (VS, XCode) ˆ cerbero: the build system used to build and package the SDK 1. Goals of the SDK Lower the barrier to entry for new GStreamer adopters - GStreamer is a huge project and it's sometimes hard to get started with - The current documentation is very good, but it can be overwhelming for developers starting with GStreamer. - It's hard to evaluate GStreamer as a solution for a project in a quick way. ✔ A new documentation site where GStreamer is described in a more generic way for newcomers. ✔ Create a new set of tutorials to introduce progressively new developers in the GStreamer concepts. Promote GStreamer as a multi-platform multimedia framework - GStreamer is the best multimedia framework on Linux (isn't it?), but still not very popular in other platforms. - It's a cross-platform framework, but we don't provide installers/packages for Windows and OS X - Developing and distributing GStreamer apps is rather tricky on Windows and OS X (no package managers like yum or apt-get to resolve deps ☹ ) ✔ Provide installers with pre-compiled binaries.

  • New Evolutions in the X Window System
    New Evolutions in the X Window System Matthieu Herrb∗ and Matthias Hopf† October 2005 Abstract This paper presents an overview of recent and on-going evolutions in the X window system. First, the state of some features will be presented that are already available for several months in the X server, but not yet widely used in applications. Then some ongoing and future evolutions will be shown: on the short term, the new EXA acceleration framework and the new modular- ized build system. The last part will focus on a longer term project: the new Xgl server architecture, based on the OpenGL technology for both 2D and 3D acceleration. Introduction The X window system celebrated its twentieth birthday last year. After some quick evolution in its early years, its development slowed down during the nineties, be- cause the system had acquired a level of maturity that made it fit most of the needs of the users of graphical work stations. But after all this time, pushed by the com- petition with other systems (Mac OS X and Microsoft Windows) the need for more advanced graphics features triggered new developments. The first part of this paper is going to describe some of these features that are already available (and have been used) for a couple of years but not necessarily known by users of the X window system. A second part will address some on-going work that will be part of the X11R7 release: a new 2D acceleration architecture and the modularization of the source tree. In the third part, a complete redesign of the device dependent layer of the X server, based on OpenGL, will be presented.

    TUGboat, Volume 34 (2013), No. 2 121 What is new in X TE EX 0.9999? Khaled Hosny One of the strengths of X TE EX is the use of external libraries from the underlying system as well as from third parties to do the heavy lifting of supporting modern font technologies and text layout require- ments, as well as various aspects of Unicode support. Unicode and modern fonts support can be hard to Figure 1: Some kerning bugs with Adobe fonts that get right and requires a great deal of time and effort; were fixed after the switch to HarfBuzz. by using those external libraries we can build upon already existing work in these areas. For OpenType layout we were using the ICU Layout Engine and Sil- ∩≨≳⊊⫌⊕⊗⊜⋚⨽⪬ Graphite for Graphite layout. On Mac OS X we were using Apple's Font Manager API for locating fonts, ATSUI for AAT layout and QuickTime for loading ∩≨≳⊊⫌⊕⊗⊜⋚⨽⪬ images. On other systems we were using FreeType and FontConfig for loading and locating fonts, and Figure 2: Some variants of mathematical symbols in Poppler for PDF images. the XITS Math font (in text mode). But all this is not without a cost; depending on external libraries requires continuous maintenance effort to catch up with changes in these external For example, some kerning improvements are shown dependencies, if we want to remain relevant. So in fig. 1. version 0.9999 of X TE EX saw a long overdue update Another benefit we get from using HarfBuzz is to the underlying libraries. support for Unicode Variation Selectors.

  • The Wayland Display Server
    The Wayland Display Server Kristian Hgsberg [email protected] July 26, 2010 1 Wayland Overview • wayland is a protocol for a new display server. • wayland is an implementation 1.1 Replacing X11 Over time, a lot of functionality have slowly moved out of the X server and into client-side libraries or kernel drivers. One of the first components to move out was font rendering, with freetype and fontconfig providing an alternative to the core X fonts. Direct rendering OpenGL as a graphics driver in a client side library. Then cairo came along and provided a modern 2D rendering library independent of X and compositing managers took over control of the rendering of the desktop. Recently with GEM and KMS in the Linux kernel, we can do modesetting outside X and schedule several direct rendering clients. The end result is a highly modular graphics stack. 1.2 Make the compositing manager the display server Wayland is a new display server building on top of all those components. We are trying to distill out the functionality in the X server that is still used by the modern Linux desktop. This turns out to be not a whole lot. Applications can allocate their own off-screen buffers and render their window contents by themselves. In the end, whats needed is a way to present the resulting window surface to a compositor and a way to receive input. This is what Wayland provides, by piecing together the components already in the eco-system in a slightly different way. X will always be relevant, in the same way Fortran compilers and VRML browsers are, but its time that we think about moving it out of the critical path and provide it as an optional component for legacy applications.

  • Font Configuration and Customization for Open Source Systems
    Font Configuration and Customization for Open Source Systems Keith Packard Research Staff Compaq Computer Corporation Cambridge Research Laboratory [email protected] Font configuration and customization has traditionally been left to each application. Fontconfig is a library designed to provide a common system that can serve to ease application development and provide users with the ability to confidently install new fonts with the expectation that they will be used by most applications. Fontconfig provides the ability for multiple configuration interfaces to affect a wide range of systems without requiring custom code for each new system. Fontconfig provides a range of services to allow applications to pick those appropriate without being forced to use the entire interface. Wide acceptance of the Fontconfig mechanisms will improve system consistency without requiring a radical redesign of existing applications. 1. Introduction The original ideas for Fontconfig came about during the design and deployment of the Xft library[xft]. Xft was originally designed to connect fonts rasterized with the FreeType[freetype] library with the X Render Extension[render] to the X window system[x]. As FreeType provided no font configuration or customization mechanisms, Xft included its own. Extending the problem of font configuration by creating yet another incompatible configuration file format. During a subsequent redesign of Xft, the configuration and customization portions of the library were extracted and moved into a separate library with the idea that they would be more useful if shared with other applications. The development of Xft-based desktop environments included the ability to configure Xft font selection. The need to embed the parser for the custom Xft configuration language made it evident that a standard configuration file format was required.
