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.

◆ 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

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

◆ 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
