Member Function Documentation

◆ AddSubsetRange()

virtual void iText.Kernel.Font.PdfFont.AddSubsetRange ( int[] range )

inlinevirtual

Adds a character range when subsetting.

Adds a character range when subsetting. The range is an int array where the first element is the start range inclusive and the second element is the end range inclusive. Several ranges are allowed in the same array. Note, #setSubset(true) will be called implicitly therefore this range is an addition to the used glyphs.

Parameters

range the character range

◆ AppendAnyGlyph()

Append any single glyph, even notdef.

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

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

Implemented in iText.Kernel.Font.PdfType0Font, and iText.Kernel.Font.PdfSimpleFont< T >.

◆ AppendGlyphs()

abstract int iText.Kernel.Font.PdfFont.AppendGlyphs	(	String	text,
		int	from,

pure virtual

Append all supported glyphs and return number of processed chars.

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

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.

Implemented in iText.Kernel.Font.PdfType0Font, and iText.Kernel.Font.PdfSimpleFont< T >.

◆ ContainsGlyph()

virtual bool iText.Kernel.Font.PdfFont.ContainsGlyph ( int unicode )

inlinevirtual

Check whether font contains glyph with specified unicode.

Parameters

unicode a unicode code point

Returns: true if font contains glyph, represented with the unicode code point, otherwise false.

◆ ConvertToBytes()

abstract byte [] iText.Kernel.Font.PdfFont.ConvertToBytes ( String text )

pure virtual

Converts the text into bytes to be placed in the document.

Converts the text into bytes to be placed in the document. The conversion is done according to the font and the encoding and the characters used are stored.

Parameters

text	the text to convert

Returns: the conversion

Implemented in iText.Kernel.Font.PdfType0Font, and iText.Kernel.Font.PdfSimpleFont< T >.

◆ DecodeIntoGlyphLine()

abstract GlyphLine iText.Kernel.Font.PdfFont.DecodeIntoGlyphLine ( PdfString content )

pure virtual

Decodes a given iText.Kernel.Pdf.PdfString containing encoded string (e.g. from content stream) into a iText.IO.Font.Otf.GlyphLine

Parameters

content the encoded string

Returns: the iText.IO.Font.Otf.GlyphLine containing the glyphs encoded by the passed string

Implemented in iText.Kernel.Font.PdfType0Font, and iText.Kernel.Font.PdfSimpleFont< T >.

◆ Flush()

override void iText.Kernel.Font.PdfFont.Flush ( )

inlinevirtual

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.

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 iText.Kernel.Pdf.PdfObjectWrapper<T>.MakeIndirect(iText.Kernel.Pdf.PdfDocument). For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.

Reimplemented from iText.Kernel.Pdf.PdfObjectWrapper< PdfDictionary >.

Reimplemented in iText.Kernel.Font.PdfType0Font.
