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.
|
|

<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.
|
|
|

|
|
|
|
|
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.
