# texelDataWithTopLeftOrigin() Returns the texture’s image data, organized such that its first pixel represents the top-left corner of the image. ``` func texelDataWithTopLeftOrigin() -> Data? ``` ## Return Value The texture’s image data, or `nil` if data is not available. ## Discussion If the texture was initialized with image data in bottom-left-origin format, the first call to this method creates and caches image data in top-left-origin format. This method returns `nil` if the texture was not initialized with image data and is not a [`MDLTexture`](/documentation/ModelIO/MDLTexture) subclass capable of loading or generating its own data. --- Copyright © 2026 Apple Inc.
