<h2> What are letest and gendata?</h2>
|
|
letest is a program you can use to verify that you have built and installed
|
|
the ICU LayoutEngine correctly. The test is not comprehensive, it just verifies
|
|
that the results of laying out some Devanagari, Arabic and Thai text are
|
|
as expected. Once this test has passed, you can use the ICU LayoutEngine in
|
|
your application knowing that it has been correctly installed and that the
|
|
basic functionality is in place.
|
|
<p>gendata is a program that is used by the ICU team to build the source file
|
|
testdata.cpp, which contains the expected results of running letest. Unless
|
|
you have changed your copy of the LayoutEngine and want to validate the changes
|
|
on other platforms, there's no reason for you to run this program. </p>
|
|
<p>(The ICU team first runs a Windows application which uses the ICU LayoutEngine
|
|
to display the text that letest uses. Once it has been verified that the text
|
|
is displayed correctly, gendata is run to produce testdata.cpp, and then
|
|
letest is run on Windows to verify that letest still works with the new data.)

<h2> How do I build letest?</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 UNIX 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 letest on Windows, just open the letest project in <icu>\source\test\letest
|
|
and build it. On UNIX systems, connect to <top-build-dir>/test/letest
|
|
and do "make all" <br>
|
|
</p>
|
|
<h2> How do I run letest?</h2>
|
|
Before you can run letest, you'll need to get the fonts it uses. For legal
|
|
reasons, we can't include them with ICU, but you can get them for free 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://www7b.boulder.ibm.com/wsdd/wspvtindex.html">
|
|
IBM WebSphere preview technologies</a> page. From this page, follow the "Download"
|
|
link on the right had side. You'll need to register with them if you haven't
|
|
downloaded before. Download and install the "Runtime Environment Package."
|
|
You'll need three fonts 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 files you want are "LucidaSansRegular.ttf" and "Thonburi.ttf" Copy these
|
|
to the directory from which you'll run letest. </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. You can download raghu.ttf
|
|
into the directory from which you'll run letest.<br>
|
|
</p>
|
|
<p>There's still one more font to get. Go to the Microsoft <a href="http://www.microsoft.com/typography/fontpack/default.htm">
|
|
TrueType core fonts for the Web</a> page and download the "Times New Roman"
|
|
font. This will download an installer program, called "Times32.exe" which
|
|
will install the Times New Roman fonts in your fonts folder. (If you've already
|
|
got these fonts in you fonts folder, you may want to move them to another
|
|
folder before you install these fonts.) </p>
|
|
<p>NOTE: this installer will display an End User License Agreement (EULA)
|
|
which you must accept before proceeding. Be sure that you read and understand
|
|
this agreement before you install the font. </p>
|
|
<p>After you run the installer program, it will add the Times Roman fonts
|
|
to your fonts folder. Open the fonts folder and copy the "Times New Roman"
|
|
font (the file name will be "Times.TTF") to the directory from which you'll
|
|
run letest. </p>
|
|
<p>That's it! Now all you have to do is run letest (CTRL+F5 in Visual C++,
|
|
or "./letest" in UNIX) If everything's OK you should see something like
|
|
this: </p>
|
|
<blockquote><tt>Test 0, font = raghu.ttf... passed.</tt> <br>
|
|
<tt>Test 1, font = Times.TTF... passed.</tt> <br>
|
|
<tt>Test 2, font = LucidaSansRegular.ttf... passed.</tt> <br>
|
|
<tt>Test 3, font = Thonburi.ttf... passed.</tt></blockquote>
