Instance Method

texelDataWithTopLeftOrigin

Returns the texture’s image data, organized such that its first pixel represents the top-left corner of the image.

Declaration

- (NSData *)texelDataWithTopLeftOrigin;

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 subclass capable of loading or generating its own data.
