public CMap()

Method Detail

toCID

public int toCID(int character)

Gets CID for given character.

Parameters:

character - is code of character, for which CID is calculated.

Returns:

CID for given character or 0 if it cannot be obtained.

containsCode

public boolean containsCode(int character)

Returns:

true if this CMap can convert given code to CID.

getCodeFromStream

public int getCodeFromStream(InputStream stream)
                      throws IOException

Reads character code from input stream and returnes it's CID. This uses codespace information from CMap. Details are described in PDF32000 in 9.7.6.2 "CMap Mapping".

Parameters:

stream - is stream from which character codes will be read.

Returns:

CID of read code.

Throws:

IOException

useCMap

public void useCMap(CMap another)

Method adds all the data needed to this CMap from another CMap.

Parameters:

another - is another CMap.

getwMode

public int getwMode()

Returns:

writing mode of given CMap.

getRegistry

public String getRegistry()

Returns:

Registry value from CIDSystemInfo dictionary.

getOrdering

public String getOrdering()

Returns:

Ordering value from CIDSystemInfo dictionary.

getSupplement

public int getSupplement()

Returns:

supplement of CMap.

setSupplement

public void setSupplement(int supplement)

isUsesNonPredefinedCMap

public boolean isUsesNonPredefinedCMap()

Returns:

true if this CMap references non-predefined CMap with usecmap operator.

setUsesNonPredefinedCMap

public void setUsesNonPredefinedCMap(boolean usesNonPredefinedCMap)

Sets indicator for CMap to contain reference to a non-predefined CMap.

getUnicode

public String getUnicode(int code)

Returns Unicode sequence for given character code.

Parameters:

code - is code of character.

Returns:

Unicode sequence obtained from this CMap.

getName

public String getName()

Returns:

name of this CMap.

getCidMappings

public List<org.verapdf.pd.font.cmap.CIDMappable> getCidMappings()
