Detailed Description

This class represents /OCProperties entry if pdf catalog and manages the layers of the pdf document.

This class represents /OCProperties entry if pdf catalog and manages the layers of the pdf document.

To be able to be wrapped with this iText.Kernel.Pdf.PdfObjectWrapper the iText.Kernel.Pdf.PdfObject must be indirect.

Constructor & Destructor Documentation

PdfOCProperties() [1/2]

iText.Kernel.Pdf.Layer.PdfOCProperties.PdfOCProperties ( PdfDocument  document )

inline

Creates a new PdfOCProperties instance.

Parameters

document

the document the optional content belongs to

PdfOCProperties() [2/2]

iText.Kernel.Pdf.Layer.PdfOCProperties.PdfOCProperties ( PdfDictionary  ocPropertiesDict )

inline

Creates a new PdfOCProperties instance by the dictionary it represents, the dictionary must be an indirect object.

Parameters

ocPropertiesDict

the dictionary of optional content properties, must have an indirect reference.

Member Function Documentation

AddOCGRadioGroup()

virtual void iText.Kernel.Pdf.Layer.PdfOCProperties.AddOCGRadioGroup ( IList< PdfLayer >  group )

inlinevirtual

Use this method to set a collection of optional content groups whose states are intended to follow a "radio button" paradigm.

Use this method to set a collection of optional content groups whose states are intended to follow a "radio button" paradigm. That is, the state of at most one optional content group in the array should be ON at a time: if one group is turned ON, all others must be turned OFF.

Parameters

group

the radio group

FillDictionary()

virtual PdfObject iText.Kernel.Pdf.Layer.PdfOCProperties.FillDictionary ( )

inlinevirtual

Fills the underlying PdfDictionary object with the current layers and their settings.

Fills the underlying PdfDictionary object with the current layers and their settings. Note that it completely regenerates the dictionary, so your direct changes to the dictionary will not take any affect.

Returns

the resultant dictionary

GetLayers()

virtual IList<PdfLayer> iText.Kernel.Pdf.Layer.PdfOCProperties.GetLayers ( )

inlinevirtual

Gets the list of all the layers currently registered in the OCProperties.

Gets the list of all the layers currently registered in the OCProperties. Note that this is just a new list and modifications to it will not affect anything.
