       image_type
           Describes the image type and must be either CL_MEM_OBJECT_IMAGE1D, CL_MEM_OBJECT_IMAGE1D_BUFFER,
           CL_MEM_OBJECT_IMAGE1D_ARRAY, CL_MEM_OBJECT_IMAGE2D, CL_MEM_OBJECT_IMAGE2D_ARRAY, or
           CL_MEM_OBJECT_IMAGE3D.

       image_width
           The width of the image in pixels. For a 2D image and image array, the image width must be ≤
           CL_DEVICE_IMAGE2D_MAX_WIDTH. For a 3D image, the image width must be ≤ CL_DEVICE_IMAGE3D_MAX_WIDTH.
           For a 1D image buffer, the image width must be ≤ CL_DEVICE_IMAGE_MAX_BUFFER_SIZE. For a 1D image and
           1D image array, the image width must be ≤ CL_DEVICE_IMAGE2D_MAX_WIDTH.

       image_height
           The height of the image in pixels. This is only used if the image is a 2D, 3D or 2D image array. For
           a 2D image or image array, the image height must be ≤ CL_DEVICE_IMAGE2D_MAX_HEIGHT. For a 3D image,
           the image height must be ≤ CL_DEVICE_IMAGE3D_MAX_HEIGHT.

       image_depth
           The depth of the image in pixels. This is only used if the image is a 3D image and must be a value ≥
           1 and ≤ CL_DEVICE_IMAGE3D_MAX_DEPTH.

       image_array_size
           The number of images in the image array. This is only used if the image is a 1D or 2D image array.
           The values for image_array_size, if specified, must be a value ≥ 1 and ≤
           CL_DEVICE_IMAGE_MAX_ARRAY_SIZE.

           Note that reading and writing 2D image arrays from a kernel with image_array_size = 1 may be lower
           performance than 2D images.

       image_row_pitch
           The scan-line pitch in bytes. This must be 0 if host_ptr is NULL and can be either 0 or ≥ image_width
           * size of element in bytes if host_ptr is not NULL. If host_ptr is not NULL and image_row_pitch = 0,
           image_row_pitch is calculated as image_width * size of element in bytes. If image_row_pitch is not 0,
           it must be a multiple of the image element size in bytes.

       image_slice_pitch
           The size in bytes of each 2D slice in the 3D image or the size in bytes of each image in a 1D or 2D
           image array. This must be 0 if host_ptr is NULL. If host_ptr is not NULL, image_slice_pitch can be
           either 0 or ≥ image_row_pitch * image_height for a 2D image array or 3D image and can be either 0 or
           ≥ image_row_pitch for a 1D image array. If host_ptr is not NULL and image_slice_pitch = 0,
           image_slice_pitch is calculated as image_row_pitch * image_height for a 2D image array or 3D image
           and image_row_pitch for a 1D image array. If image_slice_pitch is not 0, it must be a multiple of the
           image_row_pitch.

       num_mip_level, num_samples
           , Must be 0.

       buffer
           Refers to a valid buffer memory object if image_type is CL_MEM_OBJECT_IMAGE1D_BUFFER. Otherwise it
           must be NULL. For a 1D image buffer object, the image pixels are taken from the buffer object's data
           store. When the contents of a buffer object's data store are modified, those changes are reflected in
           the contents of the 1D image buffer object and vice-versa at corresponding sychronization points. The
           image_width * size of element in bytes must be ≤ size of buffer object data store.

       imageDescriptor - The image descriptor structure describes the type and dimensions of the image or image
       array and is defined as:

       typedef struct _cl_image_desc { cl_mem_object_type
       image_type; size_t image_width; size_t image_height;
       size_t image_depth; size_t image_array_size; size_t
       image_row_pitch; size_t image_slice_pitch; cl_uint
       num_mip_levels; cl_uint num_samples; cl_mem buffer; }
       cl_image_desc;

       Concurrent reading from, writing to and copying between both a buffer object and 1D image buffer object
       associated with the buffer object is undefined. Only reading from both a buffer object and 1D image
       buffer object associated with the buffer object is defined.
