  • Higher Quality 2D Text Rendering
    Journal of Computer Graphics Techniques Vol. 2, No. 1, 2013 Higher Quality 2D Text Rendering http://jcgt.org Higher Quality 2D Text Rendering Nicolas P. Rougier INRIA No hinting Native hinting Auto hinting Vertical hinting Figure 1. When displaying text on low-resolution devices (DPI < 150), one typically has to decide if one wants to respect the pixel grid (e.g., Cleartype technology / Microsoft / native hinting) for crisp rendering or, to privilege glyph shapes (Quartz technology / Apple / no hinting) at the cost of blurring. There is, however, a third way that may combine the best of the two technologies (vertical hinting). Abstract Even though text is pervasive in most 3D applications, there is surprisingly no native sup- port for text rendering in OpenGL. To cope with this absence, Mark Kilgard introduced the use of texture fonts [Kilgard 1997]. This technique is well known and widely used and en- sures both good performances and a decent quality in most situations. However, the quality may degrade strongly in orthographic mode (screen space) due to pixelation effects at large sizes and to legibility problems at small sizes due to incorrect hinting and positioning of glyphs. In this paper, we consider font-texture rendering to develop methods to ensure the highest quality in orthographic mode. The method used allows for both the accurate render- ing and positioning of any glyph on the screen. While the method is compatible with complex shaping and/or layout (e.g., the Arabic alphabet), these specific cases are not studied in this article. 50 Journal of Computer Graphics Techniques Vol.

  • Font Features for Scheherazade
    Font Features for Scheherazade The Scheherazade font includes a number of optional features that provide alternative rendering that might be preferable for use in some contexts. The chart below enumerates the details of these features. Whether these features are available to users will depend on both the application and the rendering technology (Graphite or OpenType) being used. Most features are available in both Graphite and OpenType, though there may be minor differences in their implementation. In LibreOffice 3.4.2+ (http://www.libreoffice.org/download/) or OpenOffice 3.2+ (http://www.openoffice.org/download/) the features are available only when Graphite rendering is enabled (the default). Features can be turned on by choosing the font (i.e., Scheherazade), followed by a colon, followed by the feature ID, and then followed by the feature setting. So, for example, if the “Kurdish-style Heh” is desired, the font selection would be “Scheherazade:cv48=3”. If you wish to apply two (or more) features, you can separate them with an “&”. Thus, “Scheherazade:cv48=3&cv44=1” would apply the “Kurdish-style Heh” plus the “Sindhi-style Meem” feature. In Mozilla Firefox, with either Graphite or OpenType rendering, features can be accessed using the appropriate CSS markup. A description of how to use the font features in Mozilla Firefox can be found here: http://scripts.sil.org/cms/scripts/page.php?site_id=projects&item_id=graphite_firefox#cf8a0574 (the technique described there works for both Graphite and OpenType). Ideally the selection of these font features is done in application programs, but many applications do not yet support this functionality.

  • Javatm Internationalization Roadmap
    JavaTM Internationalization Roadmap by Brian Beck – [email protected] Stuart Gill – [email protected] Norbert Lindenberg – [email protected] John O’Conner – [email protected] Sun Microsystems Inc. Introduction The Java 2 platform as available today provides a strong foundation for the development of internationalized and multilingual applications. The functionality it provides covers all the core areas of internationalization: • It uses Unicode 2.1 as its built-in character data type. • The Locale class lets applications identify locales, allowing for truly multilingual applications. • The ResourceBundle class provides the foundation for localization, including localization for multiple locales in a single application container. • The Date, Calendar, and TimeZone classes provide the basis for time handling around the globe. • The String and Character classes as well as the java.text package contain rich functionality for text processing, formatting, and parsing. • Text stream input and output classes support converting text between Unicode and other character encodings. • Keyboard handling and the input method framework allow for text input in many languages. • The Java 2D™ system supports text rendering for many of the major languages, including bidirectional text handling for Arabic and Hebrew. • The text components in the Swing user interface toolkit provide plug-and-play text editing functionality that takes full advantage of the input method framework and the 2D rendering system. • Component orientation support lets applications switch their user interfaces between left- to-right and right-to-left layouts. To date, most of our internationalization support has been focused on European, Middle Eastern, and Far East Asian locales. Those locales are now reasonably well supported so we have begun to turn our attention to the locales of South and Southeast Asia.

  • Proposal for Encoding Book Pahlavi in the Unicode Standard
    Proposal for Encoding Book Pahlavi in the Unicode Standard Version 1.1 Abe Meyers1 May 5, 2014 1abraham DOT meyers AT orientology DOT ca Foreword The purpose of this document is two-fold. First, to propose the inclusion of the Book Pahlavi script characters in the Unicode Standard, and second, to outline and address some of the shortcomings of the previous proposed encoding models [7, 20], in particular the more recent of the two [20]. The previous proposal admits that it “does not attempt to solve the multi-layer and complex problems of properly and completely representing text written in Book Pahlavi” [20, p.3]. The current proposal, on the other hand, proceeds to indeed solve those very problems. My first goal is to be able to uniquely and unambiguously represent Book Pahlavi texts in Unicode, without any loss of vital information in the transcoding process. To elaborate, first, a given shape standing for a Pahlavi word, should be able to be encoded only in one way to Unicode. Second, starting from the encoded word, only one shape must be able to be generated. Third, going through a round trip, i.e. encoding the word and then rendering it, the rendered shape and the original shape should contain the same amount of (relevant) information. In addition, I will encode the text in such a way that in the process of rendering it, no obligate ligature features and no obligate contextual shape changes, and in general no complex text layout (CTL) capabilities, are needed to get “minimum legible” text as defined by the Unicode Standard.
