Detailed Description

The PdfShading class that represents the Shading Dictionary PDF object.

Constructor & Destructor Documentation

◆ AbstractPdfShading() [1/2]

iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.AbstractPdfShading ( PdfDictionary pdfObject )

inlinepackage

Creates the AbstractPdfShading object from the existing iText.Kernel.Pdf.PdfDictionary.

Parameters

pdfObject

iText.Kernel.Pdf.PdfDictionary from which the AbstractPdfShading object will be created

◆ AbstractPdfShading() [2/2]

iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.AbstractPdfShading	(	PdfDictionary	pdfObject,
		int	type,
		PdfColorSpace	colorSpace
	)

inlinepackage

Creates the AbstractPdfShading object from the existing iText.Kernel.Pdf.PdfDictionary , using provided type and colorspace.

Parameters

pdfObject

iText.Kernel.Pdf.PdfDictionary from which the AbstractPdfShading object will be created

Parameters

type	type with which this AbstractPdfShading object will be created
colorSpace

iText.Kernel.Pdf.Colorspace.PdfColorSpace with which this AbstractPdfShading object will be created

Member Function Documentation

◆ Flush()

sealed override void iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.Flush ( )

inlinevirtual

To manually flush a PdfObject behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference.

To manually flush a PdfObject behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference. Basically this means that before flushing you need to explicitly call iText.Kernel.Pdf.PdfObjectWrapper.MakeIndirect(iText.Kernel.Pdf.PdfDocument). For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.

Reimplemented from iText.Kernel.Pdf.PdfObjectWrapper< PdfDictionary >.

◆ GetColorSpace()

virtual PdfObject iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.GetColorSpace ( )

inlinevirtual

Gets the color space in which colour values shall be expressed.

Returns

iText.Kernel.Pdf.PdfObject Color space

◆ GetFunction()

virtual PdfObject iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.GetFunction ( )

inlinevirtual

Gets the function PdfObject that represents color transitions across the shading geometry.

Returns

iText.Kernel.Pdf.PdfObject Function

◆ GetShadingType()

virtual int iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.GetShadingType ( )

inlinevirtual

Gets the shading type.

Returns: int value of iText.Kernel.Pdf.PdfName.ShadingType

◆ IsWrappedObjectMustBeIndirect()

override bool iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.IsWrappedObjectMustBeIndirect ( )

inlinepackagevirtual

Defines if the object behind this wrapper must be an indirect object in the resultant document.

Implements iText.Kernel.Pdf.PdfObjectWrapper< PdfDictionary >.

◆ MakeShading()

static iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.MakeShading ( PdfDictionary shadingDictionary )

inlinestatic

Creates the AbstractPdfShading object from the existing iText.Kernel.Pdf.PdfDictionary with corresponding type.

Parameters

shadingDictionary

iText.Kernel.Pdf.PdfDictionary from which the AbstractPdfShading object will be created

Returns: Created AbstractPdfShading object

◆ SetFunction() [1/2]

void iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.SetFunction ( IPdfFunction function )

inline

Sets the function that represents color transitions across the shading geometry as one object.

Parameters

function The iText.Kernel.Pdf.Function.IPdfFunction to set

◆ SetFunction() [2/2]

void iText.Kernel.Pdf.Colorspace.Shading.AbstractPdfShading.SetFunction ( IPdfFunction[] functions )

inline

Sets the function object that represents color transitions across the shading geometry as an array of functions.

Parameters

functions The array of iText.Kernel.Pdf.Function.IPdfFunction to be set
