Detailed Description

Looks for image streams and performs theirs optimization.

Constructor & Destructor Documentation

◆ ImageQualityOptimizer() [1/2]

iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.ImageQualityOptimizer ( )
inline

Creates an empty image quality optimizer.

◆ ImageQualityOptimizer() [2/2]

iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.ImageQualityOptimizer ( IDictionary< ImageType, IImageProcessor >  processors )
inline

Creates a new image quality optimizer with custom configuration of image processors.

Creates a new image quality optimizer with custom configuration of image processors. Note that type of the image is identifying based on iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType() call.

Parameters
processors is a map where image types are associated with processors for them

iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType()

Member Function Documentation

◆ GetImageProcessors()

virtual IDictionaryIImageProcessor> iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.GetImageProcessors ( )
inlinevirtual

Gets a copy of current configuration of the image processor.

Returns
a map where iText.IO.Image.ImageType keys are associated with actual iText.Pdfoptimizer.Handlers.Imagequality.Processors.IImageProcessor

◆ GetPredicate()

virtual PdfImageXObjectPredicate iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.GetPredicate ( )
inlinevirtual

Gets current search predicate.

Gets current search predicate. If it was not set return default implementation.

Returns
search predicate.

◆ OptimizePdf()

override void iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.OptimizePdf ( PdfDocument  document,
OptimizationSession  session 
)
inlinepackagevirtual

The method searches across all the document and for each found iText.Kernel.Pdf.Xobject.PdfImageXObject performs an optimization according to its type.

Parameters
document

Performs an optimization of the document.

Parameters
session

Performs an optimization of the document.

Implements iText.Pdfoptimizer.AbstractOptimizationHandler.

◆ SetJBig2Processor()

virtual iText.Pdfoptimizer.Handlers.ImageQualityOptimizer iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.SetJBig2Processor ( IImageProcessor  processor )
inlinevirtual

Sets a processor for iText.IO.Image.ImageType.JBIG2 images.

Sets a processor for iText.IO.Image.ImageType.JBIG2 images. Note that type of the image is identifying based on iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType() call.

Parameters
processor is an image processor to set
Returns
this instance

iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType()

◆ SetJpeg2000Processor()

virtual iText.Pdfoptimizer.Handlers.ImageQualityOptimizer iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.SetJpeg2000Processor ( IImageProcessor  processor )
inlinevirtual

Sets a processor for iText.IO.Image.ImageType.JPEG2000 images.

Sets a processor for iText.IO.Image.ImageType.JPEG2000 images. Note that type of the image is identifying based on iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType() call.

Parameters
processor is an image processor to set
Returns
this instance

◆ SetJpegProcessor()

virtual iText.Pdfoptimizer.Handlers.ImageQualityOptimizer iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.SetJpegProcessor ( IImageProcessor  processor )
inlinevirtual

Sets a processor for iText.IO.Image.ImageType.JPEG images.

Sets a processor for iText.IO.Image.ImageType.JPEG images. Note that type of the image is identifying based on iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType() call.

Parameters
processor is an image processor to set
Returns
this instance

◆ SetPngProcessor()

virtual iText.Pdfoptimizer.Handlers.ImageQualityOptimizer iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.SetPngProcessor ( IImageProcessor  processor )
inlinevirtual

Sets a processor for iText.IO.Image.ImageType.PNG images.

Sets a processor for iText.IO.Image.ImageType.PNG images. Note that type of the image is identifying based on iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType() call.

Parameters
processor is an image processor to set
Returns
this instance

◆ SetPredicate()

virtual iText.Pdfoptimizer.Handlers.ImageQualityOptimizer iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.SetPredicate ( PdfImageXObjectPredicate  predicate )
inlinevirtual

Sets a search predicate.

Sets a search predicate. Allows to provide custom implementation of iText.Pdfoptimizer.Handlers.Util.PdfImageXObjectPredicate with overridden method iText.Pdfoptimizer.Handlers.Util.PdfImageXObjectPredicate.CustomCondition(iText.Kernel.Pdf.PdfObject) to skip some types of images during optimization process.

Parameters
predicate is a predicate to set
Returns
this instance

◆ SetTiffProcessor()

virtual iText.Pdfoptimizer.Handlers.ImageQualityOptimizer iText.Pdfoptimizer.Handlers.ImageQualityOptimizer.SetTiffProcessor ( IImageProcessor  processor )
inlinevirtual

Sets a processor for iText.IO.Image.ImageType.TIFF images.

Sets a processor for iText.IO.Image.ImageType.TIFF images. Note that type of the image is identifying based on iText.Kernel.Pdf.Xobject.PdfImageXObject.IdentifyImageType() call.

Parameters
processor is an image processor to set
Returns
this instance
