tf.keras.preprocessing.image.random_zoom(
    x, zoom_range, row_axis=1, col_axis=2, channel_axis=0,
    fill_mode='nearest', cval=0.0, interpolation_order=1
)

Arguments
x	Input tensor. Must be 3D.
zoom_range	Tuple of floats; zoom range for width and height.
row_axis	Index of axis for rows in the input tensor.
col_axis	Index of axis for columns in the input tensor.
channel_axis	Index of axis for channels in the input tensor.
fill_mode	Points outside the boundaries of the input are filled according to the given mode (one of {'constant', 'nearest', 'reflect', 'wrap'}).
cval	Value used for points outside the boundaries of the input if mode='constant'.
interpolation_order	int, order of spline interpolation. see ndimage.interpolation.affine_transform

Returns
Zoomed Numpy image tensor.

Raises
ValueError	if zoom_range isn't a tuple.
