 <p>FOP is a print formatter for <a href="#XSLFO">XSL formatting objects</a> .</p>
 <p>It can be used to render an XML file containing XSL formatting objects into a page layout. The main target is PDF but other rendering targets are supported, such as AWT, PCL, text and direct printing.</p>

 <p>FOP provides both an application and a library that converts an XSL FO document into paginated output.</p>
 <p>The FOP command line application can be directly used to transform XML into PDF, PostScript, PCL and other formats, there is also an AWT based viewer integrated.</p>
 <p>The library can be used in servlets and other Java applications.</p>

 <p>XSLFO (aka XSL-FO) is an XML vocabulary that is used to specify a pagination and other styling for page layout output. The acronym “FO” stands for <strong>F</strong> ormatting <strong>O</strong> bjects. XSLFO can be used in conjunction with <a href="#XSLT">XSLT</a> to convert from any XML format into a paginated layout ready for printing or displaying.</p>
 <p>XSLFO defines a set of elements in XML that describes the way pages are set up. The contents of the pages are filled from flows. There can be static flows that appear on every page (for headers and footers) and the main flow which fills the body of the page.</p>
 <p>Synonyms: XSL FO, XSL (FO), XSL:FO, XSL-FO, Formatting Objects</p>

 <p>XSLT describes the transformation of arbitrary XML input into other XML (like XSLFO), HTML or plain text. The “T” comes from <strong>T</strong> ransformation. For historical reasons, a transformation is often also called a “style sheet”.</p>

 <p>FOP was changed to be in accordance with the latest standard (see <a href="resources.html#specs-xslfo">XSL standard</a> ).The page master for a fo:page-sequence is now referenced by the master-reference attribute. Replace the master-name attributes of your fo:page-sequence elements by master-reference attributes.

 What you probably think of as "file names" are usually URLs, in particular the <code>src</code> attribute of fo:external-graphic.</p>
 <p>Because usage of URLs is growing, you should make yourself familiar with it. The relevant specification is <a href="http://www.rfc-editor.org/rfc/rfc2396.txt">RFC 2396</a> .</p>
 <p>In a nutshell, the correct syntax for an absolute file URL is <code>file:///some/path/file.ext</code> on Unix and <code>file:///z:/some/path/file.ext</code> on Windows systems. Note the triple slash, and also that only forward slashes are used, even on windows.</p>
 <p>A relative file URL starts with anything but a slash, and doesn't have the <code>file:</code> prefix, for example <code>file.ext</code> , <code>path/file.ext</code> or <code>../file.ext</code> . The string <code>file:path/file.ext</code> is <em>not</em> a relative URL, in fact, it isn't a valid URL at all. A relative URL is subject to a resolving process, which transforms it into an absolute URL.</p>

 <p>This is often caused by an invalid FO document. Currently only very common errors are intercepted and produce a comprehensible error message. If you forgot container elements like <code>fo:page-sequence</code> or <code>fo:flow</code> and put blocks and inline elements directly as children of <code>fo:root</code> or <code>fo:page-sequence</code> , you'll only get a NullPointerException. Check whether your FO file has a proper structure. In some cases there are mandatory properties, like the master-reference in <code>fo:conditional-page-master-reference</code> , check also whether you got them right.</p>
 <p>You may find it helpful to use the <a href="#fo-validate">validation tools</a> to validate your FO document. This will catch most problems, but should not be relied upon to catch all.</p>
 <p>If you use XSLT, problems in your style sheet and in your source XML also can produce a NullPointerException. <a href="1.0/running.html#check-input">Run the transformation separately</a> to check for this, usually you'll get a detailed error message from the XSLT processor.</p>
 <p>If you turn on debugging with the " <code>-d</code> " option you may be able to see more detailed information.</p>

 <p>The most likely reason is a known problem with the Java run time environment which is triggered by rendering SVGs. Suns JDK 1.4 does not have this problem. See also <a href="#svghangs">FOP does not exit if a SVG is included</a> .</p>
 <p>Another possibility is that FOP went into a non terminating loop. Usually this is indicated by lots of log messages of the form "[INFO]: [NNNN]" which indicate a new page has been started or <a href="#boxoverflow">box overflows</a> . After some time, FOP will crash with an OutOfMemoryException.</p>
 <p>If you called the FOP command line application from some other program, for example from Java using Runtime.exec(), it may hang while trying to write log entries to the output pipe. You have to read the FOP output regularly to empty the pipe buffer. It is best to avoid exec'ing FOP, use the library interface instead.</p>

 <p>There is something too large to fit into the intended place, usually a large image, a table whose rows are kept together or a block with a space-before or space-after larger than the page size. Catch the first page showing this phenomenon and check it. If it is not obvious which element causes the trouble, remove stuff until the problem goes away. Decrease the dimensions of the offending element or property, or increase the dimension of the enclosing element or container, or remove keep-with-* properties.</p>

 <p>Leaders still work, in fact they work better than ever before. You'll just have to add <code>text-align="justify"</code> and/or <code>text-align-last="justify"</code> to the block with the leader. Be sure you haven't accidentally overridden the <code>leader-length.maximum="100%"</code> default value.</p>
 <p>Earlier versions of FOP used to expand a leader to fill the rest of the line unconditionally, anything following it, like page numbers in a TOC, was actually shifted beyond the right margin.</p>
 <p>The new implementation uses leader-length.optimum to determine where to break the line, and expands the leader only further if the line should be filled, as indicated by the text-align and text-align-last properties.</p>
 <p>Actually due to the fuzzyness of the specification both the old and the new method are conformant (although adding text after the expanded leader in the old variant never was).</p>
 <p>If you want to have a longer ruler or space in a non-justified line, you have to increase the leader-length.optimum property.</p>

 <p>This is because spec conformance has been improved.</p>
 <p>The <a href="http://www.w3.org/TR/xsl11/#force-page-count">force-page-count property</a> controls how a FO processor pads page sequences in order to get certain page counts or last page numbers. The default is " <code>auto</code> ". With this setting, if the next page sequence begins with an odd page number because you set the initial-page-number, and the current page sequence also ends with an odd page number, the processor inserts a blank page to keep odd and even page numbers alternating (similar for the case the current page sequence ends with an even page number and the next page sequence starts with an even page number).</p>

 <p>This is usually caused by setting a "height" on a table-row or table-cell and when the content is higher than the specified height. By setting "height" (a so-called corresponding property) you <a href="http://www.w3.org/TR/xsl11/#d0e4413">implicitely set</a> block-progression-dimension.minimum, block-progression-dimension.optimum and block-progression-dimension.maximum to the same value. You'll get some information about that in the warning message. Look for something like: "MinOptMax[min=opt=max=14000]".</p>
 <p>Assuming you set the height on the table-row to 14pt and your content is 75pt high, a constraint (maximum=14pt) is violated. Normally, you just want to make sure with the "height" property that the row has a minimum height. If that is so, the right solution is to specify block-progression-dimension.minimum="14pt" instead of height="14pt".</p>

 <p>This happens for <code>fo:page-number-citation</code> elements if the citation occurs before FOP formatted the requested page, usually in TOC or index pages.

 <p>No, although you might easily think so. The problem has to do with property inheritance of the start-indent and end-indent properties to which the margin properties are mapped. Apache FOP strictly adheres to the XSL-FO specification here which many other commercial FO implementations don't do to better meet end-user expectations. You can make FOP behave like these if you set <code>setBreakIndentInheritanceOnReferenceAreaBoundary(true)</code> on the FOUserAgent. The better way is to reset <code>start-indent</code> and <code>end-indent</code> to "0pt" on table-body or block-container.

 <p>If you render the same document once to a PNG or TIFF and once into a PDF, the output may not be the same, i.e. line breaks are different or lines may have different heights. The reason for this: The Java2D-based renderers use the font subsystem of Java2D/AWT. The PDF and PS renderers use FOP's own font subsystem which provides much better font metrics than Java2D. These can lead to different layout decisions when the same document is rendered with different renderers. An alternative approach to fix this problem might be available but it hasn't been tested, yet.

 <p>This phenomenon is not a bug in FOP, but rather in the dependent packages: Apache Batik, Apache Xalan-J and SAXON. The bug in Apache Batik will be fixed in the next release. In the latest release of Apache Xalan-J, the bug is already fixed. It only occurs in the Xalan version bundled with Sun's JVM, because Sun uses a rather old version.</p>
 <p>Bug description: In a namespace-enabled Level 3 DOM, an attribute in the default namespace must be set with <code>"null"</code> as the value for the namespace URI. SAX, on the other side, uses an empty string ("") to designate the default namespace. Many packages appear to not properly handle this difference in which case they still use the empty string as the namespace URI parameter for <code>org.w3c.dom.Element.setAttributeNS()</code> .</p>
 <p>Work-around: Use the latest version of Apache Xalan-J. Note that starting with JDK 1.4 it's not enough to replace Xalan-J on the normal application classpath and you need to override the Xalan-J version bundled with the Sun JVM using the <a href="http://java.sun.com/j2se/1.4.2/docs/guide/standards/">Endorsed Standards Override Mechanism</a> , i.e. you must place Xalan-J in the <code>"lib/endorsed"</code> directory of your JRE.</p>

 <p>Check the paper size in Acrobat settings and the "fit to page" print setting. Contorted printing is often caused by a mismatched paper format, for example if the setting is "US Letter" but the PDF was made for A4. Sometimes also the printer driver interferes, check its settings too.</p>

How can I get rid of strange single-pixel lines inside table borders or between table cells in Adobe Acrobat? ## <a id="acrobat-anti-aliasing"></a></h3>
 <p>Since Apache FOP supports the collapsed border model, every border segment consists of two separate shapes. This is due to the fact that each side of the border segment can have a different color. Now, Adobe Acrobat may display thin (1 pixel wide) lines inside the border segment or sometimes even between to adjacent colored rectangles making up the background of a block or table cell. This effect is due to the way Adobe Acrobat does anti-aliasing. Adobe's algorithm seems to cause these artifacts. Other PDF viewers don't have that problem. Or at least we haven't had any reports in that direction.</p>
 <p>First of all, these artifacts do not appear in print since no anti-aliasing is done by Adobe Acrobat in this case (except maybe if you tell Acrobat to print the page as a bitmap in which case Adobe fully composes the page itself). So, if the artifacts appear on screen, it doesn't mean they have to appear in print, too.</p>
 <p>To get rid of the artifacts, you can call up the "Preferences" dialog of Adobe Acrobat and select the tab "Page display". Enabling "Enhance thin lines" may help in some situations. Otherwise, you can disable "Smooth line art". You may have to disable "Use 2D graphics acceleration", too, so you can disable "Smooth line art" in the first place.</p>
 <p>Here an example of how the effect can look like (left: anti-aliasing on, right: anti-aliasing off):
 <figure alt="Left: anti-aliasing on, Right: off" src="images/acrobat-anti-aliasing-artifacts.png"></figure>
 Unfortunately, it is not possible to control the above settings from within the PDF file. The user has to change these settings himself. Improving FOP to avoid this kind of problem would be possible although rather hard to achieve because we'd need to add a considerable amount of code to combine the various line segments. Something like that has been tried already years ago showing that this is a tricky task. Also, the improvement may not justify the amount of effort required.</p>

 <p>It depends whether you mean "printing to a printer under control of the server" or "printing on the client's printer".</p>
 <p>For the first problem, look at the print servlet in the FOP examples. You'll have to gather any printer settings in a HTML form and send it to the server.</p>
 <p>For the second task, you can use some client side script to start Acrobat Reader in print mode, or use a Java applet based on the FOP print servlet. This depends heavily on the client installation and should not be relied on except in tightly controlled environments.</p>

 <p>You will get better results if you transform your source XML directly into XSLFO. It is tempting to use the XML-&gt;XHTML-&gt;XSLFO approach, because this apparently means there's only one transformation to maintain, but XHTML and publishing grade PDF are dissimilar enough that an "generic" XHTML-&gt;XSLFO(PDF) usually wont cut it, because the XHTML already lacks information from the original XML. It may be worthwhile to go from the source XML to an intermediate custom XML which on one hand is close enough to representation to allow simple transformation to either XHTML or XSLFO for most of the structure, but on the other hand retains enough semantic from the original XML that elements which must be handled differently in the two representations can be handled differently. Setting this up requires experience and most likely extensive prototyping.</p>

 <p>When entering special (non-ASCII) characters in XML, the general rule is to use the applicable Unicode character instead of trying to use a character entity as you would with HTML. Remember that HTML is an SGML document type. SGML has a limited character set, which requires it to use character entities to represent special characters. One of the improvements of XML over SGML (and thus HTML) is native support for Unicode. Basic XML has only a handful of character entities, primarily because it doesn't really need more.</p>
 <p>Entities such as <code>&amp;uuml;</code> (u with an umlaut), which work in HTML, will be flagged as undefined entities unless you define them yourself in your DTD. Use the corresponding Unicode character instead. A list of predefined HTML entities and their Unicode codepoints can be found at <a href="http://www.w3.org/TR/html4/sgml/entities.html">Character entity references in HTML 4</a> .</p>
 <p>One common example is <code>&amp;nbsp;</code> , used to obtain a non-breaking space in HTML. In XML, use &#160; instead.</p>

 Getting your XML correctly encoded is only part of the job. If you want the character to display or print correctly (and you probably do), then the selected font must contain the necessary glyph. Because of differences between font encoding methods, and limitations in some font technologies, this can be a troublesome issue, especially for symbol characters. The FOP example file <a href="fo/fonts.fo.pdf">Base-14 Font Character Mapping</a> is a very useful resource in sorting these issues out for the Base-14 fonts. For other fonts, use font editing sofware or operating system utilities (such as the Character Map in most Windows platforms) to determine what characters the font supports.</p>
 <p>An alternative to encoding the character and making it available through a font is to use an embedded graphic to represent the character: GIF, PNG, SVG, etc.</p>

 <p>The handful of basic XML character entities that do exist are the ampersand, apostrophe, less-than, greater-than, and single-quote characters. These are needed to distinguish markup tags from content, and to distinguish character entities from content. To avoid parser complaints about illegal characters and entities in your input, ensure that ampersands in text and attributes are written as &amp;, "&lt;" is written as &lt;, and "&gt;" as &gt;. It is not necessary everywhere, but it is wise to do so anyway, just to be sure.</p>
 <p>Most XML parsers will provide a line number and sometimes a column number for offending characters.</p>

 <p>If the parser complains about illegal bytes or characters in the input, or there are unexpected characters in the output, this is usually the result of a character encoding problem. See the <a href="http://www.dpawson.co.uk/xsl">XSL FAQ</a> for additional information. Many software packages that produce XML, including XSLT processors, use UTF-8 encoding as a default. If you view their output with something not aware of the encoding, like Notepad for Win95/98/ME/NT, funny characters are displayed. A � is a giveaway.</p>

 <p>To write "This page is intentionally left blank" (or something similar) on an intentionally blank page, first define a conditional page master with a page master specific for blank pages.

Otherwise, you will want to set them up so that the header does not overlap body content or the body extend into the footer.</p>
 <p>Assuming you wish to keep the regions separate, if you have a header region with an extent of 20mm, you should define a margin for the body region of at least 20mm too.
