texelDataWithBottomLeftOrigin()
Returns the texture’s image data, organized such that its first pixel represents the bottom-left corner of the image.
Declaration
func texelDataWithBottomLeftOrigin() -> 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 top-left-origin format, the first call to this method creates and caches image data in bottom-left-origin format.
This method returns nil if the texture was not initialized with image data and is not a MDLTexture subclass capable of loading or generating its own data.
