  • Method Details

    • convertImageCs

      com.itextpdf.kernel.pdf.xobject.PdfImageXObject convertImageCs (com.itextpdf.kernel.pdf.xobject.PdfImageXObject imageToConvert, OptimizationSession session)
      Converts color space of passed image.
      Parameters:
      imageToConvert - the image for which color space should be converting
      session - is an auxiliary object used to support share data between stages of optimization process
      Returns:
      the image with converted color space if converting can be performed and the same instance otherwise

    • convertContentStream

      com.itextpdf.kernel.pdf.PdfStream convertContentStream (com.itextpdf.kernel.pdf.PdfStream contentStream, com.itextpdf.kernel.pdf.PdfResources externalResources, OptimizationSession session)
      Converts color space of the passed content stream. Note that this method does not process content stream resources and passed external resources. This method doesn't convert transparency group entry, for it use attemptToConvertTransparencyGroup(PdfObject, OptimizationSession) method.
      Parameters:
      contentStream - the PDF content stream instance for conversion
      externalResources - the external content stream resources. Used in the case when the page content stream is converted, and the resources are stored not in the content stream but in the page dictionary. In other case should be null
      session - is an auxiliary object used to support share data between stages of optimization process
      Returns:
      the content stream with converted color space if converting can be performed and the same instance otherwise

    • convertStoredResources

      void convertStoredResources (OptimizationSession session)
      Converts color space of the stored content stream resources.
      Parameters:
      session - is an auxiliary object used to support share data between stages of optimization process

    • convertAnnotationIcArray

      com.itextpdf.kernel.pdf.PdfArray convertAnnotationIcArray (com.itextpdf.kernel.pdf.PdfArray icArray)
      Converts annotation interior color array.
      Parameters:
      icArray - the interior color array
      Returns:
      the converted interior color array if converting can be performed and the same instance otherwise

    • attemptToConvertTransparencyGroup

      void attemptToConvertTransparencyGroup (com.itextpdf.kernel.pdf.PdfObject groupEntryHolder, OptimizationSession session)
      Attempt to converts transparency group dictionary which stored in passed groupEntryHolder PDF object, if this groupEntryHolder can store transparency group by PDF specification.
      Parameters:
      groupEntryHolder - the PDF object which stored transparency group dictionary to convert
      session - is an auxiliary object used to support share data between stages of optimization process

    • getConverterProperties

      CsConverterProperties getConverterProperties()
      Gets current converter properties instance.
      Returns:
      the converter properties instance
