It's finally here! - a new and improved Neatpad which demonstrates the rendering capabilities of UspLib. The purpose of this is tutorial to document the UspLib API, and secondly to mention a few details about how UspLib was integrated into Neatpad's code. I very much hope that the design of UspLib is good enough that it will others to import it into their own editors and get instant styled-text support! The image above shows Neatpad's new Unicode text-rendering engine in action. Five different scripts are being displayed - Devanagari, Tamil, Thai, Arabic and of course Latin. Font-fallback is not currently supported in Neatpad, so to display all of these different scripts a suitable font must be selected.
In the example above I used the "Arial Unicode MS" font which weighs in at a hefty 22Mb! Now, don't get too exited about this latest version. The UspLib API has been documented below. To use UspLib, include the single header-file usplib.h, and link against usplib.lib. UspAllocate UspFree. Drawing styled text with Uniscribe. Uniscribe: The Missing Documentation & Examples. Introduction Microsoft created an extremely powerful API called Uniscribe that allows applications to do typography of scripts that may have complex rules for transforming the input string (a list of Unicode code points) to the proper thing that should be rendered on the screen. Unfortunately, Microsoft did not document this library very well, gave no examples, and blessed it with an extremely complex API. I have attempted to document and give examples for some aspects of the Uniscribe library that I am familiar with in the hopes that it will be useful to other developers.
This document comes from my contribution to getting Uniscribe to work in Google Chrome. You can see the production versions of the code in: UniscribeHelper.h and UniscribeHelper.cpp. Note: In the examples, I use Unicode characters rather than images, and count on your browser to be able to display complex scripts properly. Why should you use Uniscribe? Overview Uniscribe works in two modes. Disclaimer ScriptItemize hdc, psc. Uniscribe. Uniscribe. Supporting multilanguage text layout and complex scripts with Windows 2000 By F. Avery Bishop, David C. Brown, David M. Meltzer This article is provided for historic reference purposes. The three authors of this article worked in the Windows Operating System division International group at Microsoft. A multilanguage version of Windows NT 5.0 will allow per-user setting of the user-interface language.
This article assumes you’re familiar with International Windows. Introduction All international versions of Windows 2000, from Japanese to Hebrew, are based on the same binary files. For developers of global applications, the shift to a single worldwide binary strategy is welcome news; different localized versions of an application can now be developed under a single Windows 2000-based system. In this article, we'll explore techniques for developing applications that handle multilingual text and complex scripts.
