    If I run your code, the PDF is a white image 1,800 by 400.

    However, this is also what I get if I show the image instead -

    from PIL import Image
ara = Image.open("cmx3g8_wv_1998.260_0745_mcidas.ara")
ara.show()

    I presume that you think the image is not just a while rectangle? What program are you using to view the original file?

    I viewed it by converting it to a PNG and then opening the resulting file in Apple's Preview app

    from PIL import Image
ara = Image.open("cmx3g8_wv_1998.260_0745_mcidas.ara")
ara.save("output.png")

    It turns out that this situation is more complicated. See #3838 (comment)
