<b>Frequently asked questions concerning PPower4</b>
</p>
<ul>
<li><strong>Q:</strong> Do I need a full Java implementation to
run PPower4?<br>
<strong>A:</strong> No, it is sufficient for running PPower4,
to install the Java Runtime Environment (JRE) and then call
<code>jre</code> instead of <code>java</code>
</li>
<li><strong>Q:</strong> I would like to find the whole set of
options for <code>pdfpagetransition</code>.
<br>
<strong>A:</strong> This is a matter of the transition effect
for PDF files, described in section 6.4.1.4 of the
<a
href="http://partners.adobe.com/asn/developer/acrosdk/docs.html#filefmtspecs">PDF reference manual</a> by Adobe.<br>
<a href="mailto:dongen@cs.ucc.ie">Marc van Dongen</a> has kindly
prepared some additional <a href="pagetrans.tex">commands</a>
to access the effects and agreed to publish these. Thanks!<br>
For transition effects between partial builds of a page refer
to <a href="extension.pdf">the extensions demo</a>.
</li>
<li><strong>Q:</strong> Can I use thumbnails with PPower4?<br>
<strong>A:</strong> Together with the development of our new
PDF processing library we have created a <a
href="pdfthumb">program</a> to add
thumbnails to PDF files. It needs to run GhostScript as a
subprocess. This is still only available for Unix
users.
</li>
<li><strong>Q:</strong> If I run LaTeX on my document and your
examples I get an error about an undefined control
sequence <code>\pauselevel</code>.<br>
<strong>A:</strong> Make sure that there is no outdated
version of <code>pause.sty</code> in your installation
(probably from the <code>pdfslide</code> package).
</li>
<li><strong>Q:</strong> Is there a list of planned enhancements?
<br>
<strong>A:</strong>
No, all current developments are released now.
</li>
<li><strong>Q:</strong> Is there an archive of the mailing list?<br>
<strong>A:</strong> Yes, you find it (while supplies last;-)
<a href="http://www.mail-archive.com/ppower4%40iti.informatik.tu-darmstadt.de/">here</a>,
hosted by <a href="http://www.mail-archive.com/">mail-archive.com</a>.
Archiving was started on December 7, 1999. Earlier messages
are recorded only as far as they made it into my personal log.
</li>
<li><strong>Q:</strong> You have used the <code>foils.sty</code>
in your documents. I can find such a file neither in my TeX
distribution nor on CTAN. Where do I get this file?
<br>
<strong>A:</strong> <code>foils.sty</code> is created from
<code>foiltex.dtx</code>, which can be found on CTAN. Watch out
for the copyright. It is in the nonfree tree.<br>
It is not necessary to have <code>foils.sty</code> for running
PPower4. Just some examples refer to this style.
</li>
</ul>
<b>Problems and possible solutions</b>
<ul>
<li><strong>Q:</strong> When I look at the demo, the reader
comes up in full screen mode and then freezes...return and page
down do not work.
<br>
<strong>A:</strong> Make sure that the reader application has
the keyboard input focus. Maybe you have to download the demo
files to local disk, then start the reader and select the demo
document from the "File" menu.
</li>
<li><strong>Q:</strong> I tried to compile <code>exm2.tex</code> but the
background is still white.
<br>
<strong>A:</strong> To have background colors you must run
the post processor first and then view the resulting output pdf.
</li>
<li><strong>Q:</strong> I tried to use gradient background, but
my initial monochrome background is still there.
<br>
<strong>A:</strong> To have gradient colors you must run
the post processor and then view the resulting output
pdf. <br>But beware: if you use the pagecolor macro from
pdftex.def, the post processor does not remove that and it
sticks to the page covering any post processor added backgrounds.
</li>
<li><strong>Q:</strong> When I run PPower4 on presentations with
larger images, I get an error message starting with<br>
<code>Exception in thread "main" de.tu_darmstadt.sp.paul.PDFStreamException:<br>
could not read stream content from input at ...</code>
<br>
<strong>A:</strong> This happens, if you use the same file
name for input and output. While this is possible under
certain circumstances, it is not an intended usage.<br>
Use different files for input and output and this problem
should go away.
</li>
<li><strong>Q:</strong> When I typeset fractions, the bar is
written in a different color.<br>
<strong>A:</strong> This problem is independent of PPower4.
It seems to be resolved in versions 4.05 of Acrobat Reader.
Time to update your version?
</li>
<li><strong>Q:</strong> I get this message error when trying to
execute <code>ppower4.bat</code>:<br><code>
C:\xxx>C:\xxx\jdk1.2.2\jre\bin\java.exe -jar C:\xxx\pp4p.jar<br>
count = 0, total = 76<br>
Exception in thread "main" java.lang.NoClassDefFoundError: de/tu_darmstadt/sp/pp4/PPower4</code><br>
<strong>A:</strong> Most probably the file
<code>pp4p.jar</code> was damaged during download. Check the
file size, because most damages will lead to different
lengths.
</li>
</ul>
