// Use the method place holders WRITE_IMAGE to write to an ouput image.
// Mark your images as input images using the type place holders IMAGE_src_TYPE where 'src' stands for your variable name.
// To read the image size for within an OpenCL method, use the method place holders GET_IMAGE_WIDTH,
// GET_IMAGE_HEIGHT and GET_IMAGE_DEPTH.
// You find more details on these convenience place holders online: https://github.com/clEsperanto/clij-opencl-kernels
