Adjusting only the width of a picture

Say an image with size (width = 200, height = 250)

I want to change the size to (width = 400, height = 250)

How would that be possible without giving the error "IndexError: image index out of range"?

Solution

  • Use PIL:

    from PIL import Image
im=Image.open(filename)
im2=im.resize((400,250))
im2.save(filename)

    If currently, saves as new image, but if want to display it, do:

    im2.show()

    Easy as that.

    PIL.Image.resize does it.

    Note for second argument, which has a default parameter (0), it's using NearestNeighbors, if you set it to 1 it's LANCZOS, if you set it to 2 it's BILINEAR, if you set it to 3 it's BICUBIC
