Constructor Detail

PDFont

public PDFont(COSDictionary dictionary)

Constructor from COSDictionary.

Parameters:

dictionary - is font dictionary.

Method Detail

getDictionary

public COSDictionary getDictionary()

Returns:

font COSDictionary.

getFontDescriptor

public PDFontDescriptor getFontDescriptor()

Returns:

font descriptor COSDictionary.

getType

public String getType()

Returns:

font type (Type entry).

getSubtype

public ASAtom getSubtype()

Returns:

font subtype (Subtype entry).

getFontName

public ASAtom getFontName()

Returns:

font name defined by BaseFont entry in the font dictionary and FontName key in the font descriptor.

Throws:

IllegalStateException - if font names specified in font dictionary and font descriptor are different.

isSymbolic

public boolean isSymbolic()

Returns:

true if the font flags in the font descriptor dictionary mark indicate that the font is symbolic (the entry /Flags has bit 3 set to 1 and bit 6 set to 0). descriptor is null.

getEncodingMapping

public Encoding getEncodingMapping()

getEncodingMappingFromCOSObject

public static Encoding getEncodingMappingFromCOSObject(COSObject e)

getName

public String getName()

getEncoding

public COSObject getEncoding()

getFontFile2

public COSStream getFontFile2()

getDifferences

public Map<Integer,String> getDifferences()

getDifferencesFromCosEncoding

public static Map<Integer,String> getDifferencesFromCosEncoding(COSObject e)

getWidths

public COSObject getWidths()

getFirstChar

public Long getFirstChar()

getLastChar

public Long getLastChar()

readCode

public int readCode(InputStream stream)
             throws IOException

Method reads next character code from stream according to font data. It can contain from 1 to 4 bytes.

Parameters:

stream - is stream with raw data.

Returns:

next character code read.

Throws:

IOException - if reading fails.

getFontProgram

public abstract FontProgram getFontProgram()

toUnicode

public String toUnicode(int code)

Gets Unicode string for given character code. This method returns null in case when no toUnicode mapping for this character was found, so some inherited classes need to call this method, check return value on null and then implement their special logic.

Parameters:

code - is code for character.

Returns:

Unicode string

getWidth

public Double getWidth(int code)

getDefaultWidth

public Double getDefaultWidth()

isSuccessfullyParsed

public boolean isSuccessfullyParsed()

setSuccessfullyParsed

public void setSuccessfullyParsed(boolean successfullyParsed)

isSubset

protected boolean isSubset()
