impl NDPluginProcess for OverlayProcessor

fn process_array( &mut self, array: &NDArray, _pool: &NDArrayPool, ) -> ProcessResult

Process one array. Return output arrays and param updates.

fn plugin_type(&self) -> &str

Plugin type name for PLUGIN_TYPE param.

fn register_params(&mut self, base: &mut PortDriverBase) -> AsynResult<()>

Register plugin-specific params on the base. Called once during construction.

fn on_param_change( &mut self, reason: usize, params: &PluginParamSnapshot, ) -> ParamChangeResult

Called when a param changes. Reason is the param index. Return param updates to be written back to the port driver.

fn array_data_handle( &self, ) -> Option<Arc<Mutex<RawMutex, Option<Arc<NDArray>>>>>

Return a handle to the latest NDArray data for array reads. Override this in plugins like NDPluginStdArrays that serve pixel data via readInt8Array/readInt16Array/etc.
