Instance Property


A command buffer to use for image processing using Metal.



var metalCommandBuffer: MTLCommandBuffer? { get }


If you perform image processing with a Metal shader (and write output to the metalTexture property), encode your render or compute commands to this buffer. Core Image uses the same command buffer to render other effects that precede or follow your processor in a filter chain.
