Methods summary
public static (array)
# getAvailableFilters( )

Get a list of available decoding filters.

public static Decoded
# decodeFilter( $filter, $data )

Decode data using the specified filter type.

public static Decoded
# decodeFilterStandard( $data )

Standard Default decoding filter (leaves data unchanged).

public static Decoded
# decodeFilterASCIIHexDecode( $data )

ASCIIHexDecode Decodes data encoded in an ASCII hexadecimal representation, reproducing the original binary data.

public static Decoded
# decodeFilterASCII85Decode( $data )

ASCII85Decode Decodes data encoded in an ASCII base-85 representation, reproducing the original binary data.

public static Decoded
# decodeFilterLZWDecode( $data )

LZWDecode Decompresses data encoded using the LZW (Lempel-Ziv-Welch) adaptive compression method, reproducing the original text or binary data.

public static Decoded
# decodeFilterFlateDecode( $data )

FlateDecode Decompresses data encoded using the zlib/deflate compression method, reproducing the original text or binary data.

public static
# decodeFilterRunLengthDecode( $data )

RunLengthDecode Decompresses data encoded using a byte-oriented run-length encoding algorithm.

public static Decoded
# decodeFilterCCITTFaxDecode( $data )

CCITTFaxDecode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using the CCITT facsimile standard, reproducing the original data (typically monochrome image data at 1 bit per pixel).

public static Decoded
# decodeFilterJBIG2Decode( $data )

JBIG2Decode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using the JBIG2 standard, reproducing the original monochrome (1 bit per pixel) image data (or an approximation of that data).

public static Decoded
# decodeFilterDCTDecode( $data )

DCTDecode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using a DCT (discrete cosine transform) technique based on the JPEG standard, reproducing image sample data that approximates the original data.

public static Decoded
# decodeFilterJPXDecode( $data )

JPXDecode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using the wavelet-based JPEG2000 standard, reproducing the original image data.

public static Decoded
# decodeFilterCrypt( $data )

Crypt (NOT IMPLEMETED - RETURN AN EXCEPTION) Decrypts data encrypted by a security handler, reproducing the data as it was before encryption.

public static
# Error( $msg )

Throw an exception.

Properties summary
private static array $available_filters

Define a list of available filter decoders.

# array('ASCIIHexDecode', 'ASCII85Decode', 'LZWDecode', 'FlateDecode', 'RunLengthDecode')
