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

Create an ImageRenderInfo

Parameters

ctm	the coordinate transformation matrix at the time the image is rendered
imageStream	image stream object
resourceName	Parameters colorSpaceDictionary the color space dictionary from resources which are associated with the image isInline defines if the encountered image was inline

Member Function Documentation

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).

GetImage()

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

inlinevirtual

Gets an image wrapped in ImageXObject.

Gets an 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 Java.Awt.Image.BufferedImage with iText.Kernel.Pdf.Xobject.PdfImageXObject.GetBufferedImage() ;

GetImageCtm()

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

inlinevirtual

Returns

The coordinate transformation matrix which was active when this image was rendered. Coordinates are in User space.

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
