Last change on this file was 2, checked in by jkacer, 18 years ago

Added all DocBook Framework stuff:

  • DocBook DTD
  • Transformation software FOP 0.20.5 and Saxon 6
  • XSL styles
  • Rexx scripts

Also added some WarpIN-related stuff for creation of WarpIN installation packages.
This state corresponds to version 1.0.0 from November 2005, just slightly modified to carry versioning information (Rexx scripts).

362<h3>Installation</h3>
363<div style="margin-left: 0 ; border: 2px">
364<a name="N10211"></a><a name="install-instruct"></a>
365<h4>Instructions</h4>
366<div style="margin-left: 0 ; border: 2px">
367<p>Basic FOP installation consists of first unzipping the <span class="codefrag">.gz</span> file that is the distribution medium, then unarchiving the resulting <span class="codefrag">.tar</span> file in a directory/folder that is convenient on your system. Please consult your operating system documentation or Zip application software documentation for instructions specific to your site.</p>
368</div>

370<h4>Problems</h4>
371<div style="margin-left: 0 ; border: 2px">
372<p>Some Mac OSX users have experienced filename truncation problems using Stuffit to unzip and unarchive their distribution media. This is a legacy of older Mac operating systems, which had a 31-character pathname limit. Several Mac OSX users have recommended that Mac OSX users use the shell command <span class="codefrag">tar -xzf</span> instead.</p>

376<a name="N1022F"></a><a name="standalone-start"></a>
377<h3>Starting FOP as a Standalone Application</h3>
378<div style="margin-left: 0 ; border: 2px">
379<p>The usual and recommended practice for starting FOP from the command line is to run the batch file fop.bat (Windows) or the shell script fop.sh (Unix/Linux).
380If you write your own scripts, be sure to review these standard scripts to make sure that you get your environment properly configured.</p>
381<p>The standard scripts for starting FOP require that the environment variable JAVA_HOME be set to a path pointing to the appropriate Java installation on your system. Macintosh OSX includes a Java environment as part of its distribution. We are told by Mac OSX users that the path to use in this case is <span class="codefrag">/Library/Java/Home</span>. <strong>Caveat: </strong>We suspect that, as Apple releases new Java environments and as FOP upgrades the minimum Java requirements, the two will inevitably not match on some systems. Please see <a target="_top" href="http://developer.apple.com/java/faq">Java on Mac OSX FAQ</a> for information as it becomes available.</p>

429<h3>Using Xalan to Check XSL-FO Input</h3>
430<div style="margin-left: 0 ; border: 2px">
431<p>FOP sessions that use -xml and -xsl input instead of -fo input are actually controlling two distinct conversions: Tranforming XML to XSL-FO, then formatting the XSL-FO to PDF (or another FOP output format).
432Although FOP controls both of these processes, the first is included merely as a convenience and for performance reasons.
433Only the second is part of FOP's core processing.
434If a user has a problem running FOP, it is important to determine which of these two processes is causing the problem.
435If the problem is in the first process, the user's stylesheet is likely the cause.
436The FOP development team does not have resources to help with stylesheet issues, although we have included links to some useful <a href="resources.html#specs">Specifications</a> and <a href="resources.html#articles">Books/Articles</a>.
437If the problem is in the second process, FOP may have a bug or an unimplemented feature that does require attention from the FOP development team.</p>
438<div class="frame note">
439<div class="label">Note</div>
440<div class="content">The user is always responsible to provide correct XSL-FO code to FOP.</div>
441</div>
442<p>In the case of using -xml and -xsl input, although the user is responsible for the XSL-FO code that is FOP's input, it is not visible to the user. To make the intermediate FO file visible, the FOP distribution includes xalan.bat (Windows batch file) and xalan.sh (Unix/Linux script), which run only the first (transformation) step, and write the results to a file.</p>

445<div class="content">When asking for help on the FOP mailing lists, <em>never</em> attach XML and XSL to illustrate the issue. Always run the xalan script and send the resulting XSL-FO file instead. Of course, be sure that the XSL-FO file is correct before sending it.</div>

447<p>
448 The scripts are invoked the same way that <a href="http://xml.apache.org/xalan-j/commandline.html">Xalan</a> is:

461<h3>Memory Usage</h3>
462<div style="margin-left: 0 ; border: 2px">
463<p>
464FOP can consume quite a bit of memory, even though this has been continually improved.
465This is partly inherent to the formatting process and partly caused by implementation choices.
466All FO processors currently on the market have memory problems with certain layouts.
467 </p>
468<p>
469If you are running out of memory when using FOP, here are some ideas that may help:
470 </p>
471<ul>
472
473<li>
474Increase memory available to the JVM. See <a href="http://java.sun.com/j2se/1.3/docs/tooldocs/solaris/java.html">the -Xmx option</a> for more information.
475 <!--<warning>-->
476(Warning: It is usually unwise to increase the memory allocated to the JVM beyond the amount of physical RAM, as this will generally cause significantly slower performance.)
477 <!--</warning>-->
478 </li>
479
480<li>
481Avoid forward references.
482Forward references are references to some later part of a document.
483Examples include page number citations which refer to pages which follow the citation, tables of contents at the beginning of a document, and page numbering schemes that include the total number of pages in the document (<a href="faq.html#pagenum">"page N of TOTAL"</a>).
484Forward references cause all subsequent pages to be held in memory until the reference can be resolved, i.e. until the page with the referenced element is encountered.
485Forward references may be required by the task, but if you are getting a memory overflow, at least consider the possibility of eliminating them.
486A table of contents might be eliminated, relying on PDF bookmarks instead.
487Or it might be moved to the end of the document without dimishing its value very much.
488Or, in some circumstances, the paper could even be reshuffled after printing.
489 </li>
490
491<li>
492Avoid large images, especially if they are scaled down.
493If they need to be scaled, scale them in another application upstream from FOP.
494For many image formats, memory consumption is driven mainly by the size of the image file itself, not its dimensions (width*height), so increasing the compression rate may help.
495 </li>
496
497<li>
498Use multiple page sequences.
499FOP starts rendering after the end of a page sequence is encountered.
500While the actual rendering is done page-by-page, some additional memory allocated for other purposes could be freed after the page sequence has been rendered.
501 </li>
502
503<li>
504Break down large tables.
505If you don't use table headers and footers, just start a new table every N rows.
506With headers and footers, consider integrating them as normal table rows, or, if they are used at page breaks, try to put the information into static content.
507You can then use markers to change them.
508 </li>
509
510<li>
511Clear the image cache. At the moment, images in the cache are not released automatically when an OutOfMemoryError is imminent.
512Starting with version 0.20.5 however, you can call <span class="codefrag">org.apache.fop.image.FopImageFactory.resetCache()</span> to empty the
513<a target="_top" href="graphics.html#caching">image cache</a>.
514 </li>
515
516</ul>
517<p>
518There are currently some bugs which cause FOP to go into a nonterminating loop, which will also often result in a memory overflow.
519A characteristic symptom is continuous <a href="faq.html#boxoverflow">box overflows</a> in the log.
520Most of these loops are triggered by elements that do not fit in the available space, such as big images or an improperly specified width in nested block elements.
521The only workaround is to locate such problems and correct them.
522 </p>
523<p>
524One of FOP's stated design goals is to be able to process input of arbitrary size.
525Addressing this goal is one of the prime motivations behind the <a href="dev/index.html">FOP Redesign</a>.
