writeText

public void writeText(String text,
                      PdfOutputStream stream)

Specified by:

createGlyphLine

public GlyphLine createGlyphLine(String content)

Specified by:

createGlyphLine in class PdfFont

appendGlyphs

public int appendGlyphs(String text,
                        int from,
                        int to,
                        List<Glyph> glyphs)

Description copied from class: PdfFont

Append all supported glyphs and return number of processed chars. Composite font supports surrogate pairs.

Specified by:

appendGlyphs in class PdfFont

Parameters:

text - String to convert to glyphs.

from - from index of the text.

to - to index of the text.

glyphs - array for a new glyphs, shall not be null.

Returns:

number of processed chars from text.

appendAnyGlyph

public int appendAnyGlyph(String text,
                          int from,
                          List<Glyph> glyphs)

Description copied from class: PdfFont

Append any single glyph, even notdef. Returns number of processed chars: 2 in case surrogate pair, otherwise 1.

Specified by:

appendAnyGlyph in class PdfFont

Parameters:

text - String to convert to glyphs.

decode

public String decode(PdfString content)

Specified by:

decode in class PdfFont

decodeIntoGlyphLine

public GlyphLine decodeIntoGlyphLine(PdfString characterCodes)

Decodes sequence of character codes (e.g. from content stream) into a GlyphLine

Specified by:

decodeIntoGlyphLine in class PdfFont

Parameters:

characterCodes - the string which is interpreted as a sequence of character codes. Note, that PdfString acts as a storage for char code values specific to given font, therefore individual character codes must not be interpreted as code units of the UTF-16 encoding

Returns:

the GlyphLine containing the glyphs encoded by the passed string

appendDecodedCodesToGlyphsList

public boolean appendDecodedCodesToGlyphsList(List<Glyph> list,
                                              PdfString characterCodes)

Decodes sequence of character codes (e.g. from content stream) to sequence of glyphs and appends them to the passed list.

Overrides:

appendDecodedCodesToGlyphsList in class PdfFont

Parameters:

list - the list to the end of which decoded glyphs are to be added

characterCodes - the string which is interpreted as a sequence of character codes. Note, that PdfString acts as a storage for char code values specific to given font, therefore individual character codes must not be interpreted as code units of the UTF-16 encoding

Returns:

true if all codes where successfully decoded, false otherwise

getContentWidth

public float getContentWidth(PdfString content)

Specified by:

getContentWidth in class PdfFont

isBuiltWith

public boolean isBuiltWith(String fontProgram,

flush

public void flush()

Description copied from class: PdfFont

To manually flush a PdfObject behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference. Basically this means that before flushing you need to explicitly call PdfObjectWrapper.makeIndirect(PdfDocument). For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.

Overrides:

flush in class PdfFont

getCmap

public CMapEncoding getCmap()

Gets CMAP associated with the Pdf Font.

Returns:

CMAP

See Also:

CMapEncoding

                                   boolean isType2)

Generates the CIDFontType2 dictionary.

Parameters:

fontDescriptor - the font descriptor dictionary

fontName - a name of the font

isType2 - true, if the font is CIDFontType2 (TrueType glyphs), otherwise false, i.e. CIDFontType0 (Type1/CFF glyphs)

Returns:

fully initialized CIDFont

getToUnicode

public PdfStream getToUnicode()

Creates a ToUnicode CMap to allow copy and paste from Acrobat.
