使用PIL显示numpy数组

Question

I want to display a (512, 512) numpy 2d-array of uint16 values with PIL. If I wrote a function:

def display_PIL(nparray):
    image = Image.fromarray(nparray)
    image.show()

I get an error message:

Cannot handle this data type.

But if I add:

def display_PIL(nparray):
    image = Image.fromarray(nparray,'L')
    image.show()

it displays the image, but I have only the upper-right quarter of the image. Is there a solution to have the complete image? Where can I find information regarding the L option and other options?

Answer 1

The question is solved using the option 'I;16' in the Image.fromarray function. Many thanks.
