Converts a 3D Numpy array to a PIL Image instance.

Used in the notebooks

Used in the guide Used in the tutorials

Usage:

from PIL import Image
img = np.random.random(size=(100, 100, 3))
pil_img = tf.keras.preprocessing.image.array_to_img(img)

x Input Numpy array.
data_format Image data format, can be either "channels_first" or "channels_last". Defaults to None, in which case the global setting tf.keras.backend.image_data_format() is used (unless you changed it, it defaults to "channels_last").
scale Whether to rescale image values to be within [0, 255]. Defaults to True.
dtype Dtype to use. Default to None, in which case the global setting tf.keras.backend.floatx() is used (unless you changed it, it defaults to "float32")

A PIL Image instance.

ImportError if PIL is not available.
