All Implemented Interfaces:

ErrorHandler

public class Driver
extends Object
implements ErrorHandler

A driver for the conversion process.

The Driver class provides a high-level interface to set up and perform a conversion. A typical use is as follows:

1. Set conversion options using the setProperties or loadPropertyFile method.
2. Specify the conversion input source using one of the setInput methods. The input source may be specified as a character stream, a byte stream, a file name or a URL. It is represented internally by an instance of the InputSource object of the SAX API.
3. Specify the conversion output destination using one of the setOutput methods. The output destination may be specified as a character stream, a byte stream, or a file name. It is represented internally by an instance of the OutputDestination object.
4. Perform the conversion using the convert() method.

Alternatively, an application may create and initialize an InputSource object, create and initialize an OutputDestination object, and call the convert(InputSource, OutputDestination) method.

setProperty

public void setProperty(String key,
                        String value)

Sets a conversion option.

All conversion options are specified as standard Java properties. Property names and values are summarized in the table below.

Name	Value	Description	Default
alwaysSaveAsPNG	true or false	If true, do not attempt to save JPEG images as JPEG files in the output file. Instead always transcode JPEG images to PNG.	false
baseURL (1)	URL	base URL of relative paths in property values	none (paths are taken relative to the input source URL)
docx.useVML	true or false	Use VML -deprecated- elements rather than DrawingML elements to represent images	false
genericFontFamilies	A string having this syntax: map -> entry [',' entry]* entry -> generic_family '=' actual_family generic_family -> 'serif' | 'sans-serif' | 'monospace' | 'cursive' | 'fantasy'	May be used to map generic font families to actual font families.	Depends on the output format. Generally: serif=Times New Roman,sans-serif=Arial,monospace=Courier New
imageResolution	Positive integer	default image resolution in DPI. Used to compute the intrinsic size of an image when an image file does not contain resolution or absolute size information.	96
imageRendererResolution	Positive integer	default image resolution in DPI. Used to compute the intrinsic size of an image, according to the image renderer (that is, MS-Word or OpenOffice), when an image file does not contain resolution or absolute size information.	Depends on the output format. Generally 96. It is strongly recommended to use this default value.
outputEncoding	See below	output encoding	See below
outputFormat	rtf, wml, docx or odt	output format	rtf
prescaleImages	true or false	image scaling policy (2)	false
rtf.target	MSWord	target RTF viewer	none (no specified target)
screenResolution	Positive integer	screen resolution in DPI. Used to convert px lengths to other units.	96
set.graphic_factory_name.parameter_name	Depends on the parameter	Sets parameter parameter_name on graphic factory called graphic_factory_name (case-insensitive). graphic factory examples: ImageIO, WMF, EMF, SVG, MathML. Important: unlike all the other properties which only have an effect on this converter, property set.XXX.YYY immediately configures once for all specified graphic factory and have no direct effect on this converter. Example: invoking something like: Converter conv = new Converter(); conv.setProperty("set.SVG.resolution", "300"); // DPI without actually using converter conv is a simple way to configure graphic factory SVG.	Depends on the parameter
singleSidedLayout	true or false	single-sided page layout (3)	false
styles	An URL in its string form (e.g. "file:///C:/My%20Folder/styles.xfc") or a filename (e.g. "C:\My Folder\styles.xfc"). A relative filename is relative to the current working directory.	Specifies the location of an XML file containing the set of user styles to be used during the conversion.	Do not use user styles; only use direct formatting/automatic styles.

The outputEncoding property possible values depend on the target output format:

• For RTF output supported values are ASCII, Cp1250 (Windows Eastern European), Cp1251 (Windows Cyrillic) and Cp1252 (Windows Latin-1). The default value is Cp1252.
• For WML output all encodings available in the current JVM are supported. The property value may be either the encoding name (e.g. ISO8859_1) or the charset name (e.g. ISO-8859-1). The complete list of supported encodings is returned by the listEncodings method. The default value is Cp1252.
• For Open XML output the outputEncoding property specifies the encoding of XML content in the output document. Supported values are UTF-8 and UTF-16. The default value is UTF-8.
• For OpenDocument output the outputEncoding property specifies the encoding of XML content (files styles.xml and content.xml) in the output document. All encodings available in the current JVM are supported. The property value may be either the encoding name (e.g. ISO8859_1) or the charset name (e.g. ISO-8859-1). The complete list of supported encodings is returned by the listEncodings method. The default value is UTF8.

⁽¹⁾ Use of the baseURL property is deprecated. Applications should register their own URI resolver to handle URIs in property values.

⁽²⁾ By default images are not prescaled. Instead, the original size of images is preserved and scaling directives are inserted in the output document. Set the prescaleImages property to true if you prefer to minimize the size of the output document.

⁽³⁾ By default RTF, WML and Open XML output documents are given a double-sided page layout regardless of the input document properties. To force a single-sided page layout the singleSidedLayout property must be set to true.

Parameters:

key - the property name

value - the property value

setProperties, loadPropertyFile

setProperties

public void setProperties(Properties properties)

Sets conversion options.

All conversion options are specified as standard Java properties. See the setProperty method for an option summary.

Parameters:

properties - a property set

See Also:

setProperty, loadPropertyFile

loadPropertyFile

public void loadPropertyFile(String fileName)
                      throws IOException

Equivalent to loadPropertyFile(new File(fileName)).

Throws:

IOException

loadPropertyFile

public void loadPropertyFile(File file)
                      throws IOException

Reads conversion options from a file.

All conversion options are specified as standard Java properties. See the setProperty method for an option summary.

Parameters:

IOException - if an I/O error occurs

See Also:

loadUserConfiguration

loadUserConfiguration

public void loadUserConfiguration()
                           throws IOException

Reads conversion options from the user configuration file.

The user configuration file is a standard Java property file located at user_preferences_directory/xfc.properties, where user_preferences_directory is:

• $HOME/.xfc/ on Linux, Unix, etc.
• $HOME/Library/Application Support/XMLmind/FOConverter/ on Mac OS X.

setErrorHandler

public void setErrorHandler(ErrorHandler handler)

Registers a conversion error handler.

If no error handler is registered by an application, a default implementation will be used. The error method of this default handler throws an exception, while the warning method prints a warning message to the standard error output stream.

Parameters:

handler - the error handler

setUriResolver

public void setUriResolver(UriResolver resolver)

Registers a URI resolver.

An application may use this method to specify a custom URI resolver to be used for handling URIs in property values. By default URI specifications that do not denote an absolute location are considered relative to the input source URI, unless the baseURL option is set.

Parameters:

resolver - the URI resolver

See Also:

getUriResolver

getUriResolver

public UriResolver getUriResolver()

Returns the registered URI resolver.

Returns:

the URI resolver, or null if none has been specified

See Also:

setXMLReader

public void setXMLReader(XMLReader reader)

Registers an external XML reader.

An application may use this method to specify an external XML reader (org.xml.sax.XMLReader object) to be used for the conversion. If no XML reader is specified one is created internally.

Parameters:

reader - the XML reader

See Also:

getXMLReader

getXMLReader

public XMLReader getXMLReader()

Returns the registered external XML reader.

Returns:

the external XML reader, or null if none has been specified

See Also:

setXMLReader
