def gimpfu_numpy_converter.copy_array_into_layer	(		data,
			layer
	)

copies an array into a layer.

(image/layer size must match)

Parameters

layer	a gimp layer
data	a numpy array representing the layer (height x width x channels; must match the layers' size/channels). The data is converted into uint8.
