                      PdfOutputStream stream)

Specified by:

writeText in class PdfFont

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.

from - from index of the text.

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

Returns:

number of processed chars: 2 in case surrogate pair, otherwise 1

decode

public String decode(PdfString content)

Specified by:

decode in class PdfFont

public GlyphLine decodeIntoGlyphLine(PdfString content)

Decodes a given PdfString containing encoded string (e.g. from content stream) into a GlyphLine

Specified by:

decodeIntoGlyphLine in class PdfFont

Parameters:

content - the encoded string

Returns:

the GlyphLine containing the glyphs encoded by the passed string

getContentWidth

public float getContentWidth(PdfString content)

Specified by:

getContentWidth in class PdfFont

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
