<title>Readme file for the ICU LayoutEngine demo</title>
|

</head>

|
<h2> What is the layout demo?</h2>
|
|
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. <br>
|
|
|
|
<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.<br>
|
|
</p>
|
|
<h2> How do I run the demo?</h2>
|
|
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>Download the 1.3 version of the JDK from the<a
|
|
href="http://www.ibm.com/java"> IBM developerWorks Java technology zone</a>
|
|
page. From this page, follow the "Tools and products" link on the left
|
|
hand side, and then the link for the "IBM Developer Kit for Linux", or
|
|
the "IBM Developer Kit for Windows(R), Release 1.3.0". You'll need to
|
|
register with them if you haven't downloaded before. Download and
|
|
install the "Runtime Environment Package." You'll need one font from
|
|
this package. If you've let the installer use it's defaults, the fonts
|
|
will be in C:\Program Files\IBM\Java13\jre\lib\fonts. The file you want
|
|
is "Thonburi.ttf" On Windows, copy this font file to your Fonts folder,
|
|
on Linux, copy this font file to the directory from which you'll run
|
|
the layout demo.</p>
|
|
<p>Next is the Hindi font. Go to the NCST site and download <a
|
|
href="http://rohini.ncst.ernet.in/indix/download/font/raghu.ttf">
|
|
raghu.ttf</a>. Be sure to look at the <a
|
|
href="http://rohini.ncst.ernet.in/indix/download/font/README"> README</a>
|
|
file before you download the font. On Linux, you can download raghu.ttf
|
|
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://home.att.net/%7Ejameskass/">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><span style="font-weight: bold;">Note:</span> 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>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>
|
|
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>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>

You can also use the script name "DEFAULT" to represent all scripts
|
|
which you don't explicitly list in the FontMap file.<br>
|
|
<br>
|
|
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. <br>
