Since no version information was provided previously, the initial - value of this attribute is <code>2.0</code>. Future backward compatible changes will update the minor - version number, while future non-backward compatible changes will update the major version number. - </li> - <li> - On the <code>text</code> element, a new alternate representation is used for adjustments to glyph positions as expressed by a <code>dp</code> - attribute instead of the <code>dx</code> attribute. For further information, see - <a href="http://mail-archives.apache.org/mod_mbox/xmlgraphics-fop-dev/201202.mbox/%3cCACQ=j+evStXx=7hW=CHVNKCrZHUso9FHZCSk_5EoENOHcGpGOg@mail.gmail.com%3e">complex - script patch - intermediate format changes</a>. - </li> - <li> - On the <code>border-rect</code> element, the attributes {<code>before</code>, <code>after</code>, <code>start</code>, <code>end</code>} - have been renamed to {<code>top</code>, <code>bottom</code>, <code>left</code>, <code>right</code>}, respectively. - For further information, see - <a href="http://mail-archives.apache.org/mod_mbox/xmlgraphics-fop-dev/201202.mbox/%3cCACQ=j+evStXx=7hW=CHVNKCrZHUso9FHZCSk_5EoENOHcGpGOg@mail.gmail.com%3e">complex - script patch - intermediate format changes</a>. - </li> - </ul> - </li> - <li> - The <code>IFPainter</code> interface (of package <code>org.apache.fop.render.intermediate</code>), specifically the - <code>drawText</code> and <code>drawBorderRect</code> method signatures, have been modified to express the semantics of the above changes to the IF output format. - </li> - <li> - The area tree (AT) output format has underwent minor modification as follows: - <ul> - <li> - In order to track changes to the AT format, a <code>version</code> attribute has been added to the root - <code>areaTree</code> element. Since no version information was provided previously, the initial - value of this attribute is <code>2.0</code>. Future backward compatible changes will update the minor - version number, while future non-backward compatible changes will update the major version number. - </li> - <li> - An optional <code>level</code> attribute has been added to a number of element types to express resolved bidirectional level. - </li> - <li> - An optional <code>reversed</code> attribute has been added to the <code>word</code> element type to express that the glyphs that - correspond to the character content of the element should be reversed (in order) in the inline progression dimension when rendering. - </li> - </ul> - </li> - <li> - Because complex script features are now enabled by default, it is possible that different font specific data will be used for - kerning than was previously used. This may be the case if a font supports a traditional TrueType <code>kern</code> table and - also supports the advanced typographic <code>kern</code> feature with a <code>GPOS</code> table. In FOP 1.0, the former is used for kerning, - while in FOP 1.1 with complex script features enabled, the latter is used. If it is desired to explicitly use the <code>kern</code> table (rather - than the <code>GPOS</code> table) in such a case, then the <code>-nocs</code> command line option may be used when invoking FOP - in order to disable complex script features. - </li> - </ul> - </section> - <section id="pre-1.0"> - <title>Upgrading from Pre-1.0 Versions</title> - <p> - If you're planning to upgrade to the latest Apache™ FOP version from a pre-1.0 version, - there are a few very important things to consider: - </p> - <ul> - <li> - The API of FOP has changed considerably and is not - backwards-compatible with versions 0.20.5 and - 0.91beta. Version 0.92 introduced the <strong>new stable - API</strong>. - </li> - <li> - Since version 0.92 some deprecated methods which were part - of the old API have been removed. If you upgrade from 0.91 - beta, you will need to adjust your Java code. Similarly if - you upgrade from 0.92 and use deprecated methods. - </li> - <li> - If you are using a configuration file for version 0.20.5, you have to rebuild it in the new format. The format - of the configuration files has changed since version 0.20.5. See conf/fop.xconf for - an example configuration file. A XML Schema file can be found under - src/foschema/fop-configuration.xsd. - </li> - <li> - Beginning with version 0.94 you can skip the generation of - font metric files and remove the "font-metrics" attribute - in the font configuration. In the unlikely case that due to - a bug you still need to use font metrics files you will need - to regenerate the font metrics file if yours are from a FOP - version before 0.93. - </li> - <li> - <p> - The new code is much more strict about the interpretation of the XSL-FO specification. - Things that worked fine in version 0.20.5 might start to produce warnings or even errors - now. FOP 0.20.5 contains many bugs which have been corrected in the new code. - </p> - <note label="An example"> - While FOP 0.20.5 allowed you to have empty <code>fo:table-cell</code> elements, the new code - will complain about that (unless relaxed validation is enabled) because the specification - demands at least one block-level element (<code>(%block;)+</code>, see - <a href="http://www.w3.org/TR/xsl/#fo_table-cell">XSL-FO 1.1, 6.7.10</a>) - inside an <code>fo:table-cell</code> element. - </note> - </li> - <li> - Extensions and Renderers written for version 0.20.5 will not work with the new code! The new FOP - extension for <a href="http://barcode4j.sourceforge.net">Barcode4J</a> is available since - January 2007. - </li> - <li> - The SVG Renderer and the MIF Handler have not yet been resurrected! They are currently non-functional - and hope for someone to step up and reimplement them. - </li> - </ul> - <p> - When you use your existing FO files or XML/XSL files which work fine with FOP version - 0.20.5 against this FOP version some things may not work as expected. The following - list will hopefully help you to identify and correct those problems. - </p> - <ul> - <li> - Check the <a href="../compliance.html">Compliance page</a> for the feature causing - trouble. It may contain the necessary information to understand and resolve the problem. - </li> - <li> - Not all 0.20.5 output formats are supported. PDF and Postscript should be fully supported. - See <a href="output.html">Output Targets</a> for a more complete description. - </li> - <li> - As stated above, empty table cells <code><fo:table-cell></fo:table-cell></code> - are not allowed by the specification. The same applies to empty <code>fo:static-content</code> - and <code>fo:block-container</code> elements, for example. - </li> - <li> - Version 0.20.5 is not XSL-FO compliant with respect to sizing images (<code>external-graphic</code>) - or <code>instream-foreign-object</code> - objects. If images or SVGs are sized differently in your outputs with the new FOP version - check <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37136">Bug 37136</a> - as it contains some hints on what to do. The file - <a href="http://svn.apache.org/viewcvs.cgi/xmlgraphics/fop/trunk/examples/fo/basic/images.fo?view=markup"> - <code>"examples/fo/basic/images.fo"</code></a> has - a number of good examples that show the correct behaviour. - </li> - <li> - The <code>fox:outline</code> extension is not implemented in the current version: - it has been superseded by the new bookmark elements from XSL-FO 1.1. - </li> - </ul> - </section> - </body> -</document> |
