FlateDecodeFilter() [2/2]

iText.Kernel.Pdf.Filters.FlateDecodeFilter.FlateDecodeFilter ( bool  strictDecoding )

inline

Creates a FlateDecodeFilter.

Parameters

strictDecoding

defines whether the decoder will try to read a corrupted stream

Member Function Documentation

Decode()

override byte [] iText.Kernel.Pdf.Filters.FlateDecodeFilter.Decode ( byte[]  b, PdfName  filterName, PdfObject  decodeParams, PdfDictionary  streamDictionary  )

inlinevirtual

Decode the byte[] using the provided filterName.

Implements iText.Kernel.Pdf.MemoryLimitsAwareFilter.

Reimplemented in iText.Kernel.Pdf.Filters.FlateDecodeStrictFilter.

DecodePredictor()

static byte [] iText.Kernel.Pdf.Filters.FlateDecodeFilter.DecodePredictor ( byte @[]  in, PdfObject  decodeParams  )

inlinestatic

Parameters

in	Input byte array.
decodeParams	PdfDictionary of decodeParams.

Returns

a byte array

FlateDecode()

static byte [] iText.Kernel.Pdf.Filters.FlateDecodeFilter.FlateDecode ( byte @[]  in, bool  strict  )

inlinestatic

A helper to flateDecode.

Parameters

in	the input data
strict

true to read a correct stream. false to try to read a corrupted stream.

Returns

the decoded data

IsStrictDecoding()

virtual bool iText.Kernel.Pdf.Filters.FlateDecodeFilter.IsStrictDecoding ( )

inlinevirtual

Checks whether the decoder will try to read a corrupted stream (not strict) or not (strict)

Returns

true if the decoder will try to read a corrupted stream otherwise false

SetStrictDecoding()

virtual iText.Kernel.Pdf.Filters.FlateDecodeFilter iText.Kernel.Pdf.Filters.FlateDecodeFilter.SetStrictDecoding ( bool  strict )

inlinevirtual

Defines how the corrupted streams should be treated.

Parameters

strict

true if the decoder should try to read a corrupted stream otherwise false

Returns

the decoder
