Field Detail

### KEY_DEVICE_RESOLUTION

    public static final org.apache.batik.transcoder.TranscodingHints.Key KEY_DEVICE_RESOLUTION

  The key is used to specify the resolution for on-the-fly images generated due to complex effects like gradients and filters.

### KEY_STROKE_TEXT

    public static final org.apache.batik.transcoder.TranscodingHints.Key KEY_STROKE_TEXT

  The key to specify whether to stroke text instead of using text operations.

### KEY_AUTO_FONTS

    public static final org.apache.batik.transcoder.TranscodingHints.Key KEY_AUTO_FONTS

  The key is used to specify whether the available fonts should be automatically detected. The alternative is to configure the transcoder manually using a configuration file.

### VALUE_FORMAT_ON

    public static final java.lang.Boolean VALUE_FORMAT_ON

  The value to turn on text stroking.

### VALUE_FORMAT_OFF

    public static final java.lang.Boolean VALUE_FORMAT_OFF

  The value to turn off text stroking.

### userAgent

    protected org.apache.batik.bridge.UserAgent userAgent

  The user agent dedicated to this Transcoder.

Constructor Detail

### AbstractFOPTranscoder

    public AbstractFOPTranscoder()

  Constructs a new FOP-style transcoder.

Method Detail

### createUserAgent

    protected org.apache.batik.bridge.UserAgent createUserAgent()

  Creates and returns the default user agent for this transcoder. Override this method if you need non-default behaviour.

  Returns:
    UserAgent the newly created user agent

### setLogger

    public void setLogger(org.apache.commons.logging.Log logger)

  Sets the logger.

  Parameters:
    `logger` - the logger

### setEntityResolver

    public void setEntityResolver(org.xml.sax.EntityResolver resolver)

  Sets the EntityResolver that should be used when building SVG documents.

  Parameters:
    `resolver` - the resolver

### configure

    public void configure(org.apache.avalon.framework.configuration.Configuration cfg)
                   throws org.apache.avalon.framework.configuration.ConfigurationException

  {@inheritDoc}

  Throws:
    `org.apache.avalon.framework.configuration.ConfigurationException`

### getAutoFontsDefault

    protected boolean getAutoFontsDefault()

  Returns the default value for the KEY_AUTO_FONTS value.

  Returns:
    the default value

### getEffectiveConfiguration

    protected org.apache.avalon.framework.configuration.Configuration getEffectiveConfiguration()

  Returns the effective configuration for the transcoder.

  Returns:
    the effective configuration

### getLogger

    protected final org.apache.commons.logging.Log getLogger()

  Returns the logger associated with this transcoder. It returns a SimpleLog if no logger has been explicitly set.

  Returns:
    Logger the logger for the transcoder.

### createDocumentFactory

    protected org.apache.batik.dom.util.DocumentFactory createDocumentFactory(org.w3c.dom.DOMImplementation domImpl,
                                                                              java.lang.String parserClassname)

  Creates a `DocumentFactory` that is used to create an SVG DOM tree. The specified DOM Implementation is ignored and the Batik SVG DOM Implementation is automatically used.

  Parameters:
    `domImpl` - the DOM Implementation (not used)
    `parserClassname` - the XML parser classname
  Returns:
    the document factory

### isTextStroked

    protected boolean isTextStroked()

  Indicates whether text should be stroked rather than painted using text operators. Stroking text (also referred to as "painting as shapes") can used in situations where the quality of text output is not satisfying. The downside of the work-around: The generated file will likely become bigger and you will lose copy/paste functionality for certain output formats such as PDF.

  Returns:
    true if text should be stroked rather than painted using text operators

### getDeviceResolution

    protected float getDeviceResolution()

  Returns the device resolution that has been set up.

  Returns:
    the device resolution (in dpi)

### getImageManager

    protected org.apache.xmlgraphics.image.loader.ImageManager getImageManager()

  Returns the ImageManager to be used by the transcoder.

  Returns:
    the image manager

### getImageSessionContext

    protected org.apache.xmlgraphics.image.loader.ImageSessionContext getImageSessionContext()

  Returns the ImageSessionContext to be used by the transcoder.

  Returns:
    the image session context

### setupImageInfrastructure

    protected void setupImageInfrastructure(java.lang.String baseURI)

  Sets up the image infrastructure (the image loading framework).

  Parameters:
    `baseURI` - the base URI of the current document
