# getLineFragmentRect(_:usedRect:forParagraphSeparatorGlyphRange:atProposedOrigin:) Calculates the line fragment rectangle and the portion of the rectangle that contains marks. ``` func getLineFragmentRect(_ lineFragmentRect: UnsafeMutablePointer, usedRect lineFragmentUsedRect: UnsafeMutablePointer, forParagraphSeparatorGlyphRange paragraphSeparatorGlyphRange: NSRange, atProposedOrigin lineOrigin: NSPoint) ``` ## Discussion The method returns the calculated line fragment rectangle in `lineFragmentRect`, and it returns the used rectangle (the portion of the line fragment rectangle that actually contains marks) in `lineFragmentUsedRect`. The `paragraphSeparatorGlyphRange` is the range of glyphs under consideration, and `lineOrigin` is the origin point of the line fragment rectangle. A `paragraphSeparatorGlyphRange` with length 0 indicates an extra line fragment (which occurs if the last character in the paragraph is a line separator.) --- Copyright © 2026 Apple Inc.
