# CVReadOnlyPixelBuffer CVReadOnlyPixelBuffer provides an immutable view of the pixel data held by the pixel buffer. ``` final class CVReadOnlyPixelBuffer ``` ## Topics ### Initializers [`init(consuming CVMutablePixelBuffer)`](/documentation/CoreVideo/CVReadOnlyPixelBuffer/init(_:)) Initialize a read-only pixel buffer by consuming a mutable pixel buffer value. [`init(unsafeBuffer: sending CVPixelBuffer)`](/documentation/CoreVideo/CVReadOnlyPixelBuffer/init(unsafeBuffer:)) Initialize a read-only pixel buffer by transferring existing CVPixelBuffer value. ### Instance Methods [`func withUnsafeBuffer((CVPixelBuffer) throws -> sending R) rethrows -> sending R`](/documentation/CoreVideo/CVReadOnlyPixelBuffer/withUnsafeBuffer(_:)) ## Relationships ### Conforms To [`Content`](/documentation/CoreMedia/CMSampleBuffer/Content) [`ViewRepresentable`](/documentation/CoreAI/InferenceValue/ViewRepresentable) [`Copyable`](/documentation/Swift/Copyable) [`CVPixelBufferRepresentable`](/documentation/CoreVideo/CVPixelBufferRepresentable) [`CVBufferRepresentable`](/documentation/CoreVideo/CVBufferRepresentable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Escapable`](/documentation/Swift/Escapable) [`Sendable`](/documentation/Swift/Sendable) [`CVImageBufferRepresentable`](/documentation/CoreVideo/CVImageBufferRepresentable) [`ContentWithFormatDescription`](/documentation/CoreMedia/CMSampleBuffer/ContentWithFormatDescription) --- Copyright © 2026 Apple Inc.
