<section><title>Export PowerPoint slides into java.awt.Graphics2D</title>
<p>
HSLF provides a way to export slides into images. You can capture slides into java.awt.Graphics2D object (or any other)
and serialize it into a PNG or JPEG format. Please note, although HSLF attempts to render slides as close to PowerPoint as possible,
the output may look differently from PowerPoint due to the following reasons:
</p>
<ul>
<li>Java2D renders fonts differently vs PowerPoint. There are always some differences in the way the font glyphs are painted</li>
<li>HSLF uses java.awt.font.LineBreakMeasurer to break text into lines. PowerPoint may do it in a different way.</li>
<li>If a font from the presentation is not avaiable, then the JDK default font will be used.</li>
</ul>
<p>
Current Limitations:
</p>
<ul>
<li>Some types of shapes are not yet supported (WordArt, complex auto-shapes)</li>
<li>Only Bitmap images (PNG, JPEG, DIB) can be rendered in Java</li>
</ul>

POI Release Guide
(I) Prerequisites
1. You should read the <a href="http://apache.org/dev/release.html">Apache Release FAQ</a>
2. You must have shell access to people.apache.org
3. Release manager must have his public key appended to the KEYS file checked in to SVN and the key published on one of the public key servers.
More info can be found here: <a href="http://www.apache.org/dev/release-signing.html">http://www.apache.org/dev/release-signing.html</a>
4. You must have <a href="java.sun.com">JDK 1.4 / 1.5</a>
5. You must have the following utilities installed on your local machine and available in your path:
* <a href="www.openssh.com">ssh</a>
* <a href="www.gnupg.org">gnupg</a>
* <a href="www.openssl.org">openssl</a>
For Windows users, install Cygwin and make sure you have the above utilities
6. The POI build system requires two components to perform a build
* <a href="ant.apache.org">Ant</a>
* <a href="http://forrest.apache.org/">Forrest</a>.
POI 3.0.2 and 3.1 were built using Ant 1.6.2 and Forrest 0.5
(II) Making release artefacts
1. Update version id in build.xml.
2. Tag current version. Include the current revision number in the comment
{code}
$ svn cp https://svn.apache.org/repos/asf/poi/trunk \
https://svn.apache.org/repos/asf/poi/tags/$TAG \
-m "tag r649911 as 3.1-beta1"
{code}
where $TAG is the release tag, for example, REL_3_1_BETA1
3. Checkout the tagged version
{code}
cd tags
svn checkout https://svn.apache.org/repos/asf/poi/tags/TAG
{code}
4. Merge (if required)
{code}
cd $TAG
$ svn merge https://svn.apache.org/repos/asf/poi/tags/TAG \
https://svn.apache.org/repos/asf/poi/trunk
{code}
5. Start a new section in sites.xml and status.xml.
6. Build as if the vote had passed. The buid date must be +7 days from current.
{code}
ant build
{code}
After build you should have the following files in the build/dist:
{code}
poi-$TAG-$DATE.jar
poi-bin-$TAG-$DATE.tar.gz
poi-bin-$TAG-$DATE.zip
poi-contrib-$TAG-$DATE.jar
poi-scratchpad-$TAG-$DATE.jar

poi-src-$TAG-$DATE.zip
{code}
where $TAG is the release tag specified in build.xml in the version.id property, $DATE is the release date (typically +7 days from the actual build date).
7. Build Mavn POM files
{code}
ant maven-dist
{code}
8. Signing the release artifacts:
{code}
cd build/dist
for i in *.zip ; do
gpg --armor --output $i.asc --detach-sig $i;
done
for i in *.gz ; do
gpg --armor --output $i.asc --detach-sig $i;
done
{code}
Verify the signatures:
{code}
gpg --multifile --verify *.asc
{code}
9. Create MD5 checksums for all artifacts to be published:
{code}
for i in *.zip ; do
openssl md5 < $i > $i.md5
done
for i in *.gz ; do
openssl md5 < $i > $i.md5
done
{code}
10. Upload to your area at people.apache.org.
There should be two directories:
main
maven
Make sure that the all files have read permission.
(III) After the vote:
Log-in on people.apache.org
1. Go to ~/POI-3.1-BETA1
cd ~/POI-3.1-BETA1/main
BETA and ALPHA releases:
cp *-src-* /www/www.apache.org/dist/poi/dev/src
cp *-bin-* /www/www.apache.org/dist/poi/dev/bin
FINAL release:
cp *-src-* /www/www.apache.org/dist/poi/release/src
cp *-bin-* /www/www.apache.org/dist/poi/release/bin
cd ~/POI-3.1-BETA1/maven
cp -r org.apache.poi /www/people.apache.org/repo/m1-ibiblio-rsync-repository/
cp -r poi/poms /www/people.apache.org/repo/m1-ibiblio-rsync-repository/poi
2. Make sure that the files are owned by the unix group apcvs and that they are writable by this group.
3. Wait for the distributions to appear on your favourite mirror
4. Send announcements:
- to poi-user and poi-dev lists
- send announcements to announcement@apache.org, announcements@jakarta.apache.org
