public GlyphLine createGlyphLine(String content)

Specified by:

createGlyphLine in class PdfFont

appendGlyphs

public int appendGlyphs(String text,
                        int from,

Description copied from class: PdfFont

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

Overrides:

appendGlyphs in class PdfFont

Parameters:

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

getCmap

metrics - metrics[0] contains the glyph index and metrics[2] contains the Unicode code

Returns:

the stream representing this CMap or null

getFontDescriptor

protected PdfDictionary getFontDescriptor(String fontName)

Specified by:

getFontDescriptor in class PdfFont
