paragraphSpacing(afterGlyphAt:withProposedLineFragmentRect:)
Returns the paragraph spacing that is in effect after the specified glyph.
Declaration
func paragraphSpacing(afterGlyphAt glyphIndex: Int, withProposedLineFragmentRect rect: NSRect) -> CGFloatParameters
- glyphIndex:
The index of the glyph in question.
- rect:
The line fragment rectangle of the last line in the paragraph.
Return Value
The paragraph spacing—that is, the number of points of space added following a paragraph—that is in effect after the glyph specified by glyphIndex.
Discussion
The typesetter adds the number of points specified in the return value to the bottom of the line fragment rectangle specified by rect (but not to the used line fragment rectangle for that line). Paragraph spacing added after a paragraph correlates to the value returned by the paragraphSpacing method of NSParagraphStyle, which you can set using the paragraphSpacing method of NSMutableParagraphStyle.
