如何在python中创建大型缩放图像

Question

Hi I currently have a graph of many data points with error bars and I was wondering how I can create an image from this that is very long horizontally.

This image is made up of 11, 256-point graphs appended on each-other. I would like to create an image (.png) that has 256 points in it when it opens but can be scrolled to the right to see more of the same image.

Thanks!

Here is a nice script that you can use that use from Jonas Wagner . Plus, it uses the cool python builtin function map() that I have never used before this.

from PIL import Image
import sys

if not len(sys.argv) > 3:
    raise SystemExit("Usage: %s src1 [src2] .. dest" % sys.argv[0])

images = map(Image.open, sys.argv[1:-1])
w = sum(i.size[0] for i in images)
mh = max(i.size[1] for i in images)

result = Image.new("RGBA", (w, mh))

x = 0
for i in images:
    result.paste(i, (x, 0))
    x += i.size[0]

result.save(sys.argv[-1])
