Instance Method

getGlyphs(in:glyphs:characterIndexes:glyphInscriptions:elasticBits:bidiLevels:)

Extracts the information needed to lay out the provided glyphs from the provided range.

Declaration

func getGlyphs(in glyphsRange: NSRange, glyphs glyphBuffer: UnsafeMutablePointer<NSGlyph>!, characterIndexes charIndexBuffer: UnsafeMutablePointer<Int>!, glyphInscriptions inscribeBuffer: UnsafeMutablePointer<NSGlyphInscription>!, elasticBits elasticBuffer: UnsafeMutablePointer<ObjCBool>!, bidiLevels bidiLevelBuffer: UnsafeMutablePointer<UInt8>!) -> Int

Parameters

glyphsRange

The range of glyphs.

glyphBuffer

The glyphs to lay out.

charIndexBuffer

The original characters for the glyphs. Note that a glyph at index 1 is not necessarily mapped to the character at index 1, because a glyph may be for a ligature or accent.

inscribeBuffer

The inscription attributes for each glyph, which are used to layout characters that are combined together.

elasticBuffer

Contains a Boolean value indicating whether a glyph is elastic for each glyph. An elastic glyph can be made longer at the end of a line or when needed for justification.

bidiLevelBuffer

Contains the bidirectional level value generated by NSGlyphGenerator, in case a subclass chooses to use this value.

Discussion

A subclass can override this method to interact with custom glyph storage.
