Detailed Description

This is the abstract class for color space converters which are used to convert PDF objects in the original color space to PDF objects in target color space.

Constructor & Destructor Documentation

AbstractCsConverter()

iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.AbstractCsConverter ( CsConverterProperties  csConverterProperties )

inline

Creates an AbstractCsConverter.

Parameters

csConverterProperties

CsConverterProperties to be used by this AbstractCsConverter

Member Function Documentation

AttemptToConvertTransparencyGroup()

virtual void iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.AttemptToConvertTransparencyGroup ( PdfObject  groupEntryHolder, OptimizationSession  session  )

inlinevirtual

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

Implements iText.Pdfoptimizer.Handlers.Converters.ICsConverter.

ConvertAnnotationIcArray()

virtual PdfArray iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.ConvertAnnotationIcArray ( PdfArray  icArray )

inlinevirtual

Converts annotation interior color array by using of current color converter.

Parameters

icArray

Converts annotation interior color array.

Returns

Converts annotation interior color array.

Implements iText.Pdfoptimizer.Handlers.Converters.ICsConverter.

ConvertContentStream()

virtual PdfStream iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.ConvertContentStream ( PdfStream  stream, PdfResources  externalResources, OptimizationSession  session  )

inlinevirtual

Converts color space of the passed content stream.

Converts color space of the passed content stream. Note that this method does not process content stream resources and passed external resources. Also, this method saves resources for their subsequent processing within the ConvertStoredResources(iText.Pdfoptimizer.OptimizationSession) method.

Parameters

stream

Converts color space of the passed content stream.

Parameters

externalResources

Converts color space of the passed content stream.

Parameters

session

Converts color space of the passed content stream.

Returns

Converts color space of the passed content stream.

Implements iText.Pdfoptimizer.Handlers.Converters.ICsConverter.

ConvertImageCs()

virtual PdfImageXObject iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.ConvertImageCs ( PdfImageXObject  imageToConvert, OptimizationSession  session  )

inlinevirtual

Converts passed image in original color space to image in target color space.

Parameters

imageToConvert	the image in original color space
session	is an auxiliary object used to support share data between stages of optimization process

Returns

the image in target color space if converting can be performed and the same instance otherwise

Implements iText.Pdfoptimizer.Handlers.Converters.ICsConverter.

ConvertStoredResources()

virtual void iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.ConvertStoredResources ( OptimizationSession  session )

inlinevirtual

Converts color space of the stored content stream resources.

Converts color space of the stored content stream resources. Resource stored takes place within the ConvertContentStream(iText.Kernel.Pdf.PdfStream, iText.Kernel.Pdf.PdfResources, iText.Pdfoptimizer.OptimizationSession) method. Note that this method should be called after all content streams have been processed.

Parameters

session

Converts color space of the stored content stream resources.

Implements iText.Pdfoptimizer.Handlers.Converters.ICsConverter.

GetConverterProperties()

virtual CsConverterProperties iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.GetConverterProperties ( )

inlinevirtual

Gets current converter properties instance.

Returns

the converter properties instance

Implements iText.Pdfoptimizer.Handlers.Converters.ICsConverter.
