As an AI language model, I do not have access to images or image processing libraries, so I cannot provide a specific example for the `image.putdata` function. However, I can provide some information about the function.
`image.putdata` is a method in Python's image processing libraries such as Pillow and OpenCV. It is used to set the pixel values of an image from a sequence of data. This sequence of data can be a list, tuple, or any iterable object that contains a sequence of pixel values in a specific order.
The `putdata` method takes one argument, which is the sequence of pixel values, and assigns them to the image object. The sequence of data must contain the exact number of pixel values required to fill the image, which is the width multiplied by the height.
Here's a general example of how the `putdata` method can be used:
```
from PIL import Image
# create a new image object
img = Image.new('RGB', (100, 100))
# create a sequence of pixel values
data = [(255, 0, 0) for i in range(100*100)] # set all pixels to red
# set the pixel values of the image using putdata
img.putdata(data)
# display the image
img.show()
```
In this example, a new image object is created with a size of 100x100 pixels. Then, a sequence of pixel values is created using a list comprehension, which sets all pixels to red. Finally, the `putdata` method is used to assign the pixel values to the image object, and the resulting image is displayed using the `show` method.
