layoutParagraph(at:)
Lays out glyphs in the current glyph range until the next paragraph separator is reached.
Declaration
func layoutParagraph(at lineFragmentOrigin: NSPointPointer) -> IntParameters
- lineFragmentOrigin:
The upper-left corner of line fragment rectangle. On return,
lineFragmentOrigincontains the next origin.
Return Value
The next glyph index; usually the index right after the paragraph separator, but it can be inside the paragraph range if, for example, the end of the text container is reached before the paragraph separator.
Discussion
Concrete subclasses must implement this method. A concrete implementation must invoke beginParagraph(), beginLine(withGlyphAt:), endLine(withGlyphRange:), and endParagraph().
