  • Method Details

    • writeSetupCodeList

      public static void writeSetupCodeList(org.apache.xmlgraphics.ps.PSGenerator gen, List setupCodeList, String type) throws IOException
      Formats and writes a List of PSSetupCode instances to the output stream.
      Parameters:
      gen - the PS generator
      setupCodeList - a List of PSSetupCode instances
      type - the type of code section
      Throws:
      IOException - if an I/O error occurs.

    • writeEnclosedExtensionAttachments

      public static void writeEnclosedExtensionAttachments(org.apache.xmlgraphics.ps.PSGenerator gen, Collection attachmentCollection) throws IOException
      Formats and writes a Collection of PSExtensionAttachment instances to the output stream. The instances are removed from the collection when they have been written.
      Parameters:
      gen - the PS generator
      attachmentCollection - a Collection of PSExtensionAttachment instances
      Throws:
      IOException - if an I/O error occurs.

    • writeEnclosedExtensionAttachment

      public static void writeEnclosedExtensionAttachment(org.apache.xmlgraphics.ps.PSGenerator gen, PSExtensionAttachment attachment) throws IOException
      Formats and writes a PSExtensionAttachment to the output stream.
      Parameters:
      gen - the PS generator
      attachment - an PSExtensionAttachment instance
      Throws:
      IOException - if an I/O error occurs.

    • setSafeSetPageDevice

      public void setSafeSetPageDevice(boolean value)
      Sets whether or not PostScript Document Structuring Conventions (DSC) compliance are enforced.

      It can cause problems (unwanted PostScript subsystem initgraphics/erasepage calls) on some printers when the pagedevice is set. If this causes problems on a particular implementation then use this setting with a 'false' value to try and minimize the number of setpagedevice calls in the PostScript document output.

      Set this value to false if you experience unwanted blank pages in your PostScript output.

      Parameters:
      value - boolean value (default is true)

    • isSafeSetPageDevice

      public boolean isSafeSetPageDevice()
      Indicates whether the "safe setpagedevice" mode is active. See setSafeSetPageDevice(boolean) for more information.
      Returns:
      true if active

    • setDSCComplianceEnabled

      public void setDSCComplianceEnabled(boolean value)
      Sets whether or not the safe set page device macro should be used (as opposed to directly invoking setpagedevice) when setting the PostScript page device.

      This option is a useful option when you want to guard against the possibility of invalid/unsupported PostScript key/values being placed in the page device.

      Parameters:
      value - setting to false and the renderer will make a standard "setpagedevice" call, setting to true will make a safe set page device macro call (default is false).

    • isDSCComplianceEnabled

      public boolean isDSCComplianceEnabled()
      Returns:
      true if DSC complicance is enabled

    • setAutoRotateLandscape

      public void setAutoRotateLandscape(boolean value)
      Controls whether landscape pages should be rotated.
      Parameters:
      value - true to enable the rotation

    • isAutoRotateLandscape

      public boolean isAutoRotateLandscape()
      Indicates whether landscape pages are rotated.
      Returns:
      true if landscape pages are to be rotated

    • setLanguageLevel

      public void setLanguageLevel(int level)
      Sets the PostScript language level.
      Parameters:
      level - the PostScript language level (Only 2 and 3 are currently supported)

    • getLanguageLevel

      public int getLanguageLevel()
      Indicates the selected PostScript language level.
      Returns:
      the PostScript language level

    • setAcrobatDownsample

      public void setAcrobatDownsample(boolean b)

    • isAcrobatDownsample

      public boolean isAcrobatDownsample()

    • setOptimizeResources

      public void setOptimizeResources(boolean value)
      Controls whether PostScript resources are optimized in a second pass over the document. Enable this to obtain smaller PostScript files.
      Parameters:
      value - true to enable resource optimization

    • isOptimizeResources

      public boolean isOptimizeResources()
      Indicates whether PostScript resources are optimized in a second pass over the document.
      Returns:
      true if resource optimization is enabled

    • setRenderingMode

      public void setRenderingMode(org.apache.fop.render.ps.PSRenderingMode renderingMode)
      Sets the rendering mode.
      Parameters:
      renderingMode - the rendering mode

    • getRenderingMode

      public org.apache.fop.render.ps.PSRenderingMode getRenderingMode()
      Returns the rendering mode.
      Returns:
      the rendering mode
