Interface for color space converting of PDF objects.

Member Function Documentation

AttemptToConvertTransparencyGroup()

void iText.Pdfoptimizer.Handlers.Converters.ICsConverter.AttemptToConvertTransparencyGroup	(	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

Implemented in iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.

ConvertAnnotationIcArray()

PdfArray iText.Pdfoptimizer.Handlers.Converters.ICsConverter.ConvertAnnotationIcArray

(

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

Implemented in iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.

ConvertContentStream()

PdfStream iText.Pdfoptimizer.Handlers.Converters.ICsConverter.ConvertContentStream	(	PdfStream	contentStream,
		PdfResources	externalResources,
		OptimizationSession	session
	)

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. This method doesn't convert transparency group entry, for it use AttemptToConvertTransparencyGroup(iText.Kernel.Pdf.PdfObject, iText.Pdfoptimizer.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

Implemented in iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.

ConvertImageCs()

PdfImageXObject iText.Pdfoptimizer.Handlers.Converters.ICsConverter.ConvertImageCs	(	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

Implemented in iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.

ConvertStoredResources()

void iText.Pdfoptimizer.Handlers.Converters.ICsConverter.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

Implemented in iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.

GetConverterProperties()

CsConverterProperties iText.Pdfoptimizer.Handlers.Converters.ICsConverter.GetConverterProperties

(

)

Gets current converter properties instance.

Returns

the converter properties instance

Implemented in iText.Pdfoptimizer.Handlers.Converters.AbstractCsConverter.
