# Applying projective transformations to images Warp images in three dimensions. ## Topics ### Computing a projective transformation from source and destination quadrilaterals [`func vImageGetPerspectiveWarp(UnsafePointer<(Float, Float)>, UnsafePointer<(Float, Float)>, UnsafeMutablePointer, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageGetPerspectiveWarp(_:_:_:_:)) Returns a projective-transformation structure that defines the mapping between a source quadrilateral and a destination quadrilateral. [`struct vImage_PerpsectiveTransform`](/documentation/Accelerate/vImage_PerpsectiveTransform) A projective-transformation matrix. ### Warping planar buffers [`func vImagePerspectiveWarp_Planar8(UnsafePointer, UnsafePointer, UnsafeMutableRawPointer!, UnsafePointer, vImage_WarpInterpolation, Pixel_8, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePerspectiveWarp_Planar8(_:_:_:_:_:_:_:)) Applies a perspective warp to an 8-bit planar image. [`func vImagePerspectiveWarp_Planar16F(UnsafePointer, UnsafePointer, UnsafeMutableRawPointer!, UnsafePointer, vImage_WarpInterpolation, Pixel_16F, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePerspectiveWarp_Planar16F(_:_:_:_:_:_:_:)) Applies a perspective warp to a floating-point 16-bit planar image. [`func vImagePerspectiveWarp_Planar16U(UnsafePointer, UnsafePointer, UnsafeMutableRawPointer!, UnsafePointer, vImage_WarpInterpolation, Pixel_16U, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePerspectiveWarp_Planar16U(_:_:_:_:_:_:_:)) Applies a perspective warp to a unsigned 16-bit planar image. ### Warping interleaved buffers [`func vImagePerspectiveWarp_ARGB8888(UnsafePointer, UnsafePointer, UnsafeMutableRawPointer!, UnsafePointer, vImage_WarpInterpolation, UnsafeMutablePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePerspectiveWarp_ARGB8888(_:_:_:_:_:_:_:)) Applies a perspective warp to an 8-bit-per-channel, four-channel interleaved image. [`func vImagePerspectiveWarp_ARGB16F(UnsafePointer, UnsafePointer, UnsafeMutableRawPointer!, UnsafePointer, vImage_WarpInterpolation, UnsafeMutablePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePerspectiveWarp_ARGB16F(_:_:_:_:_:_:_:)) Applies a perspective warp to a floating-point 16-bit , four-channel interleaved image. [`func vImagePerspectiveWarp_ARGB16U(UnsafePointer, UnsafePointer, UnsafeMutableRawPointer!, UnsafePointer, vImage_WarpInterpolation, UnsafeMutablePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImagePerspectiveWarp_ARGB16U(_:_:_:_:_:_:_:)) Applies a perspective warp to an unsigned 16-bit , four-channel interleaved image. --- Copyright © 2026 Apple Inc.
