# LoupeMarkup A loupe magnifier that magnifies the content below the loupe. ``` struct LoupeMarkup ``` ## Overview The loupe magnifies the content beneath its frame within the parent markup. The loupe centers the magnified region on the center of its frame. ## Topics ### Creating a loupe [`init(frame: CGRect, magnification: CGFloat, strokeColor: CGColor?, lineWidth: CGFloat, allowedInteractions: MarkupInteractions, id: MarkupID)`](/documentation/PaperKit/LoupeMarkup/init(frame:magnification:strokeColor:lineWidth:allowedInteractions:id:)) Initializes and returns a new loupe markup from the specified parameters. ### Configuring appearance [`var magnification: CGFloat`](/documentation/PaperKit/LoupeMarkup/magnification) The magnification level applied to the content displayed within the loupe. [`var strokeColor: CGColor?`](/documentation/PaperKit/LoupeMarkup/strokeColor) The color of the loupe’s border. [`var lineWidth: CGFloat`](/documentation/PaperKit/LoupeMarkup/lineWidth) The width of the loupe’s border in points. ### Identifying markup [`var id: MarkupID`](/documentation/PaperKit/LoupeMarkup/id) Stable unique identity of the markup. ## Relationships ### Conforms To [`Identifiable`](/documentation/Swift/Identifiable) [`Markup`](/documentation/PaperKit/Markup) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
