Here's a sample of some text written in Sanskrit: श्रीमद् भगवद्गीता अध्याय अर्जुन विषाद योग धृतराष्ट्र उवाच। धर्मक्षेत्रे कुरुक्षेत्रे समवेता युयुत्सवः मामकाः पाण्डवाश्चैव किमकुर्वत संजय Here's a sample of some text written in Arabic: أساسًا، تتعامل الحواسيب فقط مع الأرقام، وتقوم بتخزين الأحرف والمحارف الأخرى بعد أن تُعطي رقما معينا لكل واحد منها. وقبل اختراع "يونِكود"، كان هناك مئات الأنظمة للتشفير وتخصيص هذه الأرقام للمحارف، ولم يوجد نظام تشفير واحد يحتوي على جميع المحارف الضرورية and here's a sample of some text written in Thai: บทที่๑พายุไซโคลนโดโรธีอาศัยอยู่ท่ามกลางทุ่งใหญ่ในแคนซัสกับลุงเฮนรีชาวไร่และป้าเอ็มภรรยาชาวไร่บ้านของพวกเขาหลังเล็กเพราะไม้สร้างบ้านต้องขนมาด้วยเกวียนเป็นระยะทางหลายไมล์	1.66 KB	2022-04-07 22:41

For composite fonts, * if there is no single physical font which can render all of the text, * return a physical font which can render an initial substring of the text, * and set the <code>offset</code> parameter to the end of that substring. * * Internally, the LayoutEngine works with runs of text all in the same * font and script, so it is best to call this method with text which is * in a single script, passing the script code in as a hint. If you don't * know the script of the text, you can use zero, which is the script code * for characters used in more than one script. * * The default implementation of this method is intended for instances of * <code>LEFontInstance</code> which represent a physical font. It returns * <code>this</code> and indicates that the entire string can be rendered. * * This method will return a valid <code>LEFontInstance</code> unless you * have passed illegal parameters, or an internal error has been encountered. * For composite fonts, it may return the warning <code>LE_NO_SUBFONT_WARNING</code> * to indicate that the returned font may not be able to render all of * the text. Whenever a valid font is returned, the <code>offset</code> parameter * will be advanced by at least one. * * Subclasses which implement composite fonts must override this method. * Where it makes sense, they should use the script code as a hint to render * characters from the COMMON script in the font which is used for the given * script. For example, if the input text is a series of Arabic words separated * by spaces, and the script code passed in is <code>arabScriptCode</code> you * should return the font used for Arabic characters for all of the input text, * including the spaces.

All Rights Reserved." /> <meta name="Author" content="Eric Mader" /> <title>Readme file for the ICU LayoutEngine demo</title> </head> <body> <h2>What is the layout demo?</h2> <p>The layout demo displays a paragraph of text that is laid out using the LayoutEngine. There are two versions of this demo, "layout.exe" which runs on Windows 2000, and "gnomelayout" which runs on Linux. Both programs read a file containing the Unicode text to display, and a file that says which font to use to display each script.</p> <h2>How do I build the layout demo?</h2>First, you need to build ICU, including the LayoutEngine. <p>On Windows, the layout project should be listed as a dependency of all, so layout will build when you build all. If it doesn't for some reason, just select the layout project in the project toolbar and build it.</p> <p>On Linux systems, you need to add the "--enable-layout=yes" option when you invoke the runConfigureICU script. When you've done that, layout should build when you do "make all install"</p> <p>To build the demo on Windows, just open the layout project in <icu>\source\samples\layout and build it.</p> <p>On Linux systems, connect to <top-build-dir>/samples/layout and do "make all". To build the layout demo on Linux, you'll need the gnome-libs-devel and freetype-devel packages, which should be part of your Linux distribution. The demo uses the FreeType 1 library, and the make files assume that the FreeType header files are in /usr/include/freetype1, and that the freetype library is /usr/lib/libttf.so. This is how RedHat Linux 7.2 installs FreeType 1. If your system is different, you may need to add sym links to where the files are stored on your system, or modify <top-src-dir>/samples/layout/Makefile.in to reference the files correctly for your system.</p> <h2>How do I run the demo?</h2> <p>Before you can run the demo, you'll need to get the fonts it uses. For legal reasons, we can't include these fonts with ICU, but you can download them from the web. To do this, you'll need access to a computer running Windows. Here's how to get the fonts:</p> <p>First, download the Thai font. Go to <a href= "http://www.freelang.net/fonts/index.php">freelang.net</a> and click on the link for the Courier Thai font. This will download a .ZIP file. Extract the Courpro.ttf font. On Windows, copy this font file to your Fonts folder (note the name of the font after it is installed), on Linux, copy this font file to the directory from which you'll run the layout demo.</p> <p>Next is the Hindi font. Download the font from <a href= "http://www.ffonts.net/Raghindi.font.download">Raghindi</a>. On Linux, you can download the font into the directory from which you'll run the layout demo. On Windows, you'll need to install it in your Fonts folder.</p> <p>There's still one more font to get, the Code2000 Unicode font. Go to James Kass' <a href="http://www.code2000.net/">Unicode Support In Your Browser</a> page and click on the link that says "Click Here to download Code2000 shareware demo Unicode font." This will download a .ZIP file which contains CODE2000.TTF and CODE2000.HTM. Expand this .ZIP file. If you're going to run the layout demo on Linux, put the CODE2000.TTF file in the directory from which you'll run the demo. On Windows, copy the font to your fonts folder.</p> <p><strong>Note:</strong> The Code2000 font is shareware. If you want to use it for longer than a trial period, you should send a shareware fee to James. Directions for how to do this are in CODE2000.HTM.</p> <p>Be sure that your FontMap.GDI (on Windows) or FontMap.Gnome file (on Linux) contains accurate font names for each script type. For example, the following is a valid FontMap.GDI (assuming you have the correct fonts): <br><br>DEVANAGARI: Raghindi<br>THAI: Courier MonoThai<br>DEFAULT: Code2000<br><br>Note that only the Code2000 default font is strictly necessary, and that the other two can simply be commented out by a '#' if you do not wish to use them.</p> <p>Also note that the FontMap and the sample.txt files have to be in the same directory as the layout executable.</p> <p>That's it! Now all you have to do is run letest (CTRL+F5 in Visual C++, or "./gnomelayout" in Linux)</p> <h2>How can I customize the layout demo?</h2> <p>The text that the layout demo displays is read from the file "Sample.txt." You can change the text by editing this file using a Unicode-aware text editor. (it is in UTF8 format with a BOM as the first character; the demo can also read UTF16 and UTF32 format files) Remember that the text will be displayed in a single paragraph; you can include CR and LF characters in the text, but they will be ignored.</p> <p>If you add scripts to the text other than Arabic, Devanagari, Latin or Thai, you'll need to find a font which contains the characters in that script, and add an entry to the FontMap file ("FontMap.GDI" on Windows, "FontMap.Gnome" on Linux) This file contains a single entry per line. Each entry contains a script name followed by a colon, and then a font name.</p> <p>Here is the list of legal script names:</p> <blockquote> <tt>ARABIC</tt><br /> <tt>ARMENIAN</tt><br /> <tt>BENGALI</tt><br /> <tt>BOPOMOFO</tt><br /> <span style="font-family: monospace;">BUHID</span><br /> <tt>CANADIAN_ABORIGINAL</tt><br /> <tt>CHEROKEE</tt><br /> <tt>CYRILLIC</tt><br /> <tt>DESERET</tt><br /> <tt>DEVANAGARI</tt><br /> <tt>ETHIOPIC</tt><br /> <tt>GEORGIAN</tt><br /> <tt>GOTHIC</tt><br /> <tt>GREEK</tt><br /> <tt>GUJARATI</tt><br /> <tt>GURMUKHI</tt><br /> <tt>HAN</tt><br /> <tt>HANGUL</tt><br /> <span style="font-family: monospace;">HANUNOO</span><br /> <tt>HEBREW</tt><br /> <tt>HIRAGANA</tt><br /> <tt>KANNADA</tt><br /> <tt>KATAKANA</tt><br /> <tt>KHMER</tt><br /> <tt>LATIN</tt><br /> <tt>MALAYALAM</tt><br /> <tt>MONGOLIAN</tt><br /> <tt>MYANMAR</tt><br /> <tt>OGHAM</tt><br /> <tt>OLD_ITALIC</tt><br /> <tt>ORIYA</tt><br /> <tt>RUNIC</tt><br /> <tt>SINHALA</tt><br /> <tt>SYRIAC</tt><br /> <span style="font-family: monospace;">TAGALOG<br /> TAGBANWA</span><br /> <tt>TAMIL</tt><br /> <tt>TELUGU</tt><br /> <tt>THAANA</tt><br /> <tt>THAI</tt><br /> <tt>TIBETAN</tt><br /> <tt>YI<br /></tt> </blockquote> <p>You can also use the script name "DEFAULT" to represent all scripts which you don't explicitly list in the FontMap file.</p> <p>On Windows use the full name of the font as it appears in the Windows Fonts folder (eg. "Times New Roman") On Linux, use the file name of the font file (e.g. "Times.TTF") If you're running on Windows, you'll need to install the new fonts in your Fonts folder. If you're running on Linux, put them in the directory from which you'll run the demo.</p><br /> </body> </html>	7.32 KB	2022-04-07 22:41
