AddExtraEncoding()

static void iTextSharp.text.pdf.PdfEncodings.AddExtraEncoding ( String  name, IExtraEncoding  enc  )

static

Adds an extra encoding.

Parameters

name	the name of the encoding. The encoding recognition is case insensitive
enc	the conversion class

ClearCmap()

static void iTextSharp.text.pdf.PdfEncodings.ClearCmap ( String  name )

static

Clears the CJK cmaps from the cache. If name is the empty string then all the cache is cleared. Calling this method has no consequences other than the need to reload the cmap if needed.

Parameters

name	the name of the cmap to clear or all the cmaps if the empty string

ConvertCmap() [1/2]

static String iTextSharp.text.pdf.PdfEncodings.ConvertCmap ( String  name, byte[]  seq  )

static

Converts a byte array encoded as name to a CID string. This is needed to reach some CJK characters that don't exist in 16 bit Unicode.

The font to use this result must use the encoding "Identity-H" or "Identity-V".

See ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/.

Parameters

name	the CJK encoding name
seq	the byte array to be decoded

Returns

the CID string

ConvertCmap() [2/2]

static String iTextSharp.text.pdf.PdfEncodings.ConvertCmap ( String  name, byte[]  seq, int  start, int  length  )

static

Converts a byte array encoded as name to a CID string. This is needed to reach some CJK characters that don't exist in 16 bit Unicode.

The font to use this result must use the encoding "Identity-H" or "Identity-V".

See ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/.

Parameters

name	the CJK encoding name
start	the start offset in the data
length	the number of bytes to convert
seq	the byte array to be decoded

Returns

the CID string

ConvertToBytes() [1/2]

static byte [] iTextSharp.text.pdf.PdfEncodings.ConvertToBytes ( char  char1, String  encoding  )

static

Converts a String to a byte array according to the font's encoding.

Returns

an array of byte representing the conversion according to the font's encoding

Parameters

encoding	the encoding
char1	the char to be converted

ConvertToBytes() [2/2]

static byte [] iTextSharp.text.pdf.PdfEncodings.ConvertToBytes ( string  text, string  encoding  )

static

Converts a string to a byte array according to the font's encoding.

Parameters

text	the string to be converted

Returns

an array of byte representing the conversion according to the font's encoding

ConvertToString()

static string iTextSharp.text.pdf.PdfEncodings.ConvertToString ( byte[]  bytes, string  encoding  )

static

IsPdfDocEncoding()

static bool iTextSharp.text.pdf.PdfEncodings.IsPdfDocEncoding ( String  text )

static

Checks is text only has PdfDocEncoding characters.

Parameters

text	the String to test

Returns

true if only PdfDocEncoding characters are present

LoadCmap()

static void iTextSharp.text.pdf.PdfEncodings.LoadCmap ( String  name, byte  newline[][]  )

static

Loads a CJK cmap to the cache with the option of associating sequences to the newline.

Parameters

name	the CJK cmap name
newline	the sequences to be replaced bi a newline in the resulting CID. See CRLF_CID_NEWLINE

CRLF_CID_NEWLINE

byte [][] iTextSharp.text.pdf.PdfEncodings.CRLF_CID_NEWLINE = new byte[][]{new byte[]{(byte)'\n'}, new byte[]{(byte)'\r', (byte)'\n'}}

static

Assumes that '\n' and '\r\n' are the newline sequences. It may not work for all CJK encodings. To be used with LoadCmap().
