# CVMetalTextureGetCleanTexCoords(_:_:_:_:_:) Returns convenient normalized texture coordinates for the part of the image that should be displayed. ``` func CVMetalTextureGetCleanTexCoords(_ image: CVMetalTexture, _ lowerLeft: UnsafeMutablePointer, _ lowerRight: UnsafeMutablePointer, _ upperRight: UnsafeMutablePointer, _ upperLeft: UnsafeMutablePointer) ``` ## Parameters `image` A CoreVideo Metal texture-based image buffer. `lowerLeft` An array that holds two `float` values. Upon return, the array contains the `s` and `t` texture coordinates for the lower left corner of the image. `lowerRight` An array that holds two `float` values. Upon return, the array contains the `s` and `t` texture coordinates for the lower right corner of the image. `upperRight` An array that holds two `float` values. Upon return, the array contains the `s` and `t` texture coordinates for the upper right corner of the image. `upperLeft` An array that holds two `float` values. Upon return, the array contains the `s` and `t` texture coordinates for the upper left corner of the image. ## Discussion This function automatically takes into account whether or not the texture is flipped. --- Copyright © 2026 Apple Inc.
