Detailed Description

Represents image data from a PDF.

Constructor & Destructor Documentation

◆ ImageRenderInfo()

iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.ImageRenderInfo	(	Stack< CanvasTag >	canvasTagHierarchy,
		CanvasGraphicsState	gs,
		Matrix	ctm,
		PdfStream	imageStream,
		PdfName	resourceName,
		PdfDictionary	colorSpaceDictionary,
		bool	isInline
	)

inline

Creates an ImageRenderInfo.

Parameters

canvasTagHierarchy	the hierarchy of nested canvas tags for the text from the most inner (nearest to text) tag to the most outer
gs	the canvas graphics state
ctm	the coordinate transformation matrix at the time the image is rendered
imageStream	the image stream object
resourceName	the name of the image resource
colorSpaceDictionary	the color space dictionary from resources which are associated with the image
isInline	defines if the encountered image was inline

Member Function Documentation

◆ GetArea()

virtual float iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetArea ( )

inlinevirtual

Gets the size of the image in User space units.

Returns: the size of the image, in User space units

◆ GetCanvasTagHierarchy()

virtual IList<CanvasTag> iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetCanvasTagHierarchy ( )

inlinevirtual

Gets hierarchy of the canvas tags that wraps given text.

Returns: list of the wrapping canvas tags. The first tag is the innermost (nearest to the text).

◆ GetColorSpaceDictionary()

virtual PdfDictionary iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetColorSpaceDictionary ( )

inlinevirtual

Gets the color space dictionary of the image.

Returns: the color space dictionary from resources which are associated with the image

◆ GetImage()

virtual PdfImageXObject iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetImage ( )

inlinevirtual

Gets the image wrapped in ImageXObject.

Gets the image wrapped in ImageXObject. You can:

get image bytes with iText.Kernel.Pdf.Xobject.PdfImageXObject.GetImageBytes(bool) , these image bytes represent native image, i.e you can write these bytes to disk and get just an usual image;
obtain PdfStream object which contains image dictionary with iText.Kernel.Pdf.PdfObjectWrapper.GetPdfObject() method;
convert image to System.Drawing.Bitmap with iText.Kernel.Pdf.Xobject.PdfImageXObject.GetBufferedImage() ;

Returns: the image

◆ GetImageCtm()

virtual Matrix iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetImageCtm ( )

inlinevirtual

Gets the coordinate transformation matrix in User space which was active when this image was rendered.

Returns: the coordinate transformation matrix in User space which was active when this image was rendered

◆ GetImageResourceName()

virtual PdfName iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetImageResourceName ( )

inlinevirtual

Gets the name of the image resource.

Returns: the name of the image resource

◆ GetMcid()

virtual int iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetMcid ( )

inlinevirtual

Gets the marked-content identifier associated with this ImageRenderInfo instance

Returns: associated marked-content identifier or -1 in case content is unmarked

◆ GetStartPoint()

virtual Vector iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.GetStartPoint ( )

inlinevirtual

Gets the vector in User space representing the start point of the image.

Returns: the vector in User space representing the start point of the image

◆ HasMcid() [1/2]

virtual bool iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.HasMcid ( int mcid )

inlinevirtual

Checks if the text belongs to a marked content sequence with a given mcid.

Parameters

mcid	a marked content id

Returns: true if the text is marked with this id

◆ HasMcid() [2/2]

virtual bool iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.HasMcid	(	int	mcid,
		bool	checkTheTopmostLevelOnly
	)

inlinevirtual

Checks if the text belongs to a marked content sequence with a given mcid.

Parameters

mcid	a marked content id
checkTheTopmostLevelOnly	indicates whether to check the topmost level of marked content stack only

Returns: true if the text is marked with this id

◆ IsInline()

virtual bool iText.Kernel.Pdf.Canvas.Parser.Data.ImageRenderInfo.IsInline ( )

inlinevirtual

Gets the inline flag.

Returns

true if image was inlined in original stream
