  • Method Details

    • getDataName

      protected String getDataName()
      Returns the name of the data segment associated with this image form.
      Returns:
      the data segment name

    • getAdditionalFilters

      private String getAdditionalFilters(PSGenerator gen)

    • generatePaintProc

      protected void generatePaintProc(PSGenerator gen) throws IOException
      Generates the PostScript code for the PaintProc of the form.
      Specified by:
      generatePaintProc in class FormGenerator
      Parameters:
      gen - the PostScript generator
      Throws:
      IOException - if an I/O error occurs

    • generateAdditionalDataStream

      protected void generateAdditionalDataStream(PSGenerator gen) throws IOException
      Generates some PostScript code right after the form definition (used primarily for bitmap data).
      Overrides:
      generateAdditionalDataStream in class FormGenerator
      Parameters:
      gen - the PostScript generator
      Throws:
