<title>Readme file for the ICU LayoutEngine demo</title>
</head>
<body>
<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>First, download the Thai font. Go to <a href="http://www.into-asia.com/thai_language/thaifont/">
into-asia.com</a> and click on the link for the Angsana font. This will
download a .ZIP file. Extract the font file, angsd___.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>Here is the list of legal script names:

</tt></blockquote>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.
