# drawingGroup(opaque:colorMode:) Composites this view’s contents into an offscreen image before final display. ``` nonisolated func drawingGroup(opaque: Bool = false, colorMode: ColorRenderingMode = .nonLinear) -> some View ``` ## Parameters `opaque` A Boolean value that indicates whether the image is opaque. The default is `false`; if set to `true`, the alpha channel of the image must be `1`. `colorMode` One of the working color space and storage formats defined in [`ColorRenderingMode`](/documentation/SwiftUI/ColorRenderingMode). The default is [`ColorRenderingMode.nonLinear`](/documentation/SwiftUI/ColorRenderingMode/nonLinear). ## Return Value A view that composites this view’s contents into an offscreen image before display. ## Discussion The `drawingGroup(opaque:colorMode:)` modifier flattens a subtree of views into a single view before rendering it. In the example below, the contents of the view are composited to a single bitmap; the bitmap is then displayed in place of the view: ``` VStack { ZStack { Text("DrawingGroup") .foregroundColor(.black) .padding(20) .background(Color.red) Text("DrawingGroup") .blur(radius: 2) } .font(.largeTitle) .compositingGroup() .opacity(1.0) } .background(Color.white) .drawingGroup() ``` > Important: The visual result of a drawing group only includes views > that SwiftUI rasterizes directly using its own drawing primitives, > such as text, images, shapes, and composite views of these types. > It will not include views whose contents are composited by Core > Animation layers, such as more complex controls and containers, web > views, media players, and most types of UIKit and AppKit views. In > those cases, the output displays a placeholder image instead. > Whether a particular view is rendered using SwiftUI’s own drawing > primitives or composited by Core Animation may change in future > releases. However, any view that is currently supported is > guaranteed to remain supported.  --- Copyright © 2026 Apple Inc.
