Converts a XSL-FO file to another format, typically a page description language such as PDF.

Attributes:

Parameter child elements are passed to the XSL-FO processor in order to parametrize its behavior. These parameters are described in the documentation of the XSL-FO processors.

If the url attribute of a parameter child element is specified and its value is true, the parameter value must be a relative or absolute URL (properly escaped like all URLs). In such case, the value of the parameter is the fully resolved URL.

XFC example:

<parameter name="outputEncoding">Cp1252</parameter>

XEP example:

<parameter name="PS.LANGUAGE_LEVEL">2</parameter>

In addition to actual parameters, some XSL-FO processors may also support a number of pseudo-parameters. The documentation of these pseudo-parameters is displayed in the documentation pane of the dialog box of Options → Install Add-ons.

The processFO optional child element:

This optional child element specifies which FO processor to use when the FO processor specified by the parent processFO element is not available.

Example: try to use FOP when XEP is not available:

<processFO processor="XEP" file="__doc.fo" to="__doc.pdf">
  <parameter name="OUTPUT_FORMAT">pdf</parameter>

  <processFO processor="FOP" file="__doc.fo" to="__doc.pdf">
    <parameter name="renderer">pdf</parameter>
    <parameter name="configuration" url="true">fop.xconf</parameter>
  </processFO>
</processFO>
