  • Method Details

    • writeFontDict

      public static Map writeFontDict(org.apache.xmlgraphics.ps.PSGenerator gen, FontInfo fontInfo) throws IOException
      Generates the PostScript code for the font dictionary. This method should only be used if no "resource optimization" is performed, i.e. when the fonts are not embedded in a second pass.
      Parameters:
      gen - PostScript generator to use for output
      fontInfo - available fonts
      Returns:
      a Map of PSResource instances representing all defined fonts (key: font key)
      Throws:
      IOException - in case of an I/O problem

    • writeFontDict

      public static Map writeFontDict(org.apache.xmlgraphics.ps.PSGenerator gen, FontInfo fontInfo, PSEventProducer eventProducer) throws IOException
      Generates the PostScript code for the font dictionary. This method should only be used if no "resource optimization" is performed, i.e. when the fonts are not embedded in a second pass.
      Parameters:
      gen - PostScript generator to use for output
      fontInfo - available fonts
      eventProducer - to report events
      Returns:
      a Map of PSResource instances representing all defined fonts (key: font key)
      Throws:
      IOException - in case of an I/O problem

    • writeFontDict

      public static Map writeFontDict(org.apache.xmlgraphics.ps.PSGenerator gen, FontInfo fontInfo, Map<String,Typeface> fonts, PSEventProducer eventProducer) throws IOException
      Generates the PostScript code for the font dictionary. This method assumes all used fonts and characters are known, i.e. when PostScript is generated with resource optimization turned on.
      Parameters:
      gen - PostScript generator to use for output
      fontInfo - available fonts
      fonts - the set of fonts to work with
      eventProducer - the event producer
      Returns:
      a Map of PSResource instances representing all defined fonts (key: font key)
      Throws:
      IOException - in case of an I/O problem

    • determineSuppliedFonts

      public static Map determineSuppliedFonts(org.apache.xmlgraphics.ps.dsc.ResourceTracker resTracker, FontInfo fontInfo, Map<String,Typeface> fonts)
      Determines the set of fonts that will be supplied with the PS file and registers them with the resource tracker. All the fonts that are being processed are returned as a Map.
      Parameters:
      resTracker - the resource tracker
      fontInfo - available fonts
      fonts - the set of fonts to work with
      Returns:
      a Map of PSResource instances representing all defined fonts (key: font key)

    • defineEncoding

      public static org.apache.xmlgraphics.ps.PSResource defineEncoding(org.apache.xmlgraphics.ps.PSGenerator gen, SingleByteEncoding encoding) throws IOException
      Defines the single-byte encoding for use in PostScript files.
      Parameters:
      gen - the PostScript generator
      encoding - the single-byte encoding
      Returns:
      the PSResource instance that represents the encoding
      Throws:
      IOException - In case of an I/O problem

    • defineDerivedFont

      public static org.apache.xmlgraphics.ps.PSResource defineDerivedFont(org.apache.xmlgraphics.ps.PSGenerator gen, String baseFontName, String fontName, String encoding) throws IOException
      Derives a new font based on an existing font with a given encoding. The encoding must have been registered before.
      Parameters:
      gen - the PostScript generator
      baseFontName - the font name of the font to derive from
      fontName - the font name of the new font to be define
      encoding - the new encoding (must be predefined in the PS file)
      Returns:
      the PSResource representing the derived font
      Throws:
      IOException - In case of an I/O problem
