Class: FDFDoc

Core.PDFNet. FDFDoc


new FDFDoc()

FDFDoc is a class representing Forms Data Format (FDF) documents. FDF is typically used when submitting form data to a server, receiving the response, and incorporating it into the interactive form. It can also be used to export form data to stand-alone files that can be stored, transmitted electronically, and imported back into the corresponding PDF interactive form. In addition, beginning in PDF 1.3, FDF can be used to define a container for annotations that are separate from the PDF document to which they apply.

Methods


<static> create()

Default constructor that creates an empty new document.
Returns:
A promise that resolves to an object of type: "PDFNet.FDFDoc"
Type
Promise.<Core.PDFNet.FDFDoc>

<static> createFromMemoryBuffer(buf)

Open a SDF/Cos document from a memory buffer. Note: the document should be fully loaded in the memory buffer. Note: the buffer ownership is not transfered to the Document so the user should clean-up if necessary.
Parameters:
Name Type Description
buf ArrayBuffer | Int8Array | Uint8Array | Uint8ClampedArray a memory buffer containing the serialized document
Returns:
A promise that resolves to an object of type: "PDFNet.FDFDoc"
Type
Promise.<Core.PDFNet.FDFDoc>

<static> createFromStream(stream)

Open an existing FDF document
Parameters:
Name Type Description
stream Core.PDFNet.Filter input stream containing a serialized document. The input stream may be a random-access file, memory buffer, slow HTTP connection etc. Note: if the input stream doesn't support Seek() operation the document will load whole data stream in memory before parsing. In case of linearized FDF, the document may be parsed on-the-fly while it is being loaded in memory. Note that since StdFile implements Seek() interface, the document does not have to be fully in memory before it is used. Note: Make sure to call InitSecurityHandler() after FDFDoc(...) for encrypted documents.
Returns:
A promise that resolves to an object of type: "PDFNet.FDFDoc"
Type
Promise.<Core.PDFNet.FDFDoc>

<static> createFromXFDF(file_name)

Create a new FDFDoc from XFDF input. Input can be either a XFDF file path, or the XFDF data itself.
Parameters:
Name Type Description
file_name string string containing either the file path to a XFDF file, or the XML buffer containing the XFDF.
Returns:
A promise that resolves to a new FDFDoc.
Type
Promise.<Core.PDFNet.FDFDoc>

<static> createXFDFExportOptions()

Method to create a XFDFExportOptions object
Returns:
A promise that resolves to a PDFNet.FDFDoc.XFDFExportOptions.
Type
Promise.<Core.PDFNet.FDFDoc.XFDFExportOptions>

destroy()

Destructor
Inherited From:
Returns:
Type
Promise.<void>

fieldCreate(field_name, type [, field_value])

Create a new interactive form FDFField.
Parameters:
Name Type Argument Description

type number
PDFNet.Field.Type = {
	e_button : 0
	e_check : 1
	e_radio : 2
	e_text : 3
	e_choice : 4
	e_signature : 5
	e_null : 6
}
field_value Core.PDFNet.Obj <optional>
Returns:
A promise that resolves to
Type
Promise.<Core.PDFNet.FDFField>

fieldCreateFromString(field_name, type, field_value)

Parameters:
Name Type Description
field_name string
type number
PDFNet.Field.Type = {
	e_button : 0
	e_check : 1
	e_radio : 2
	e_text : 3
	e_choice : 4
	e_signature : 5
	e_null : 6
}
field_value string
Returns:
A promise that resolves to an object of type: "PDFNet.FDFField"
Type
Promise.<Core.PDFNet.FDFField>

getFDF()

Returns:
A promise that resolves to the FDF dictionary located in "/Root" or NULL if dictionary is not present.
Type
Promise.<Core.PDFNet.Obj>

getField(field_name)

Parameters:
Name Type Description
field_name string a string representing the fully qualified name of the field (e.g. "employee.name.first").
Returns:
A promise that resolves to a FDFField associated with the given field_name or invalid field (null) if the field is not found.
Type
Promise.<Core.PDFNet.FDFField>

getFieldIterator(field_name)

An interactive form (sometimes referred to as an AcroForm) is a collection of fields for gathering information interactively from the user. A FDF document may contain any number of fields appearing on any combination of pages, all of which make up a single, global interactive form spanning the entire document. The following methods are used to access and manipulate Interactive form fields (sometimes referred to as AcroForms).
Parameters:
Name Type Description
field_name string String representing the name of the FDFField to get.
Returns:
A promise that resolves to an iterator to the FDFField in the document. Note: if the document has no AcroForms, HasNext() will return false.
Type
Promise.<Core.PDFNet.Iterator.<Core.PDFNet.FDFField>>

getFieldIteratorBegin()

An interactive form (sometimes referred to as an AcroForm) is a collection of fields for gathering information interactively from the user. A FDF document may contain any number of fields appearing on any combination of pages, all of which make up a single, global interactive form spanning the entire document. The following methods are used to access and manipulate Interactive form fields (sometimes referred to as AcroForms).
Returns:
A promise that resolves to an iterator to the first FDFField in the document. Note: if the document has no AcroForms, HasNext() will return false.
Type
Promise.<Core.PDFNet.Iterator.<Core.PDFNet.FDFField>>
