我有一个像这样的小背景图片:
它比我的图像尺寸小,所以我需要反复绘制它。 (想想 css 中的背景重复)
我搜索了很多,但找不到解决方案....非常感谢。
最佳答案
根据 Marcin 链接到的代码,这将在较大的图像上平铺背景图像:
from PIL import Image
# Opens an image
bg = Image.open("NOAHB.png")
# The width and height of the background tile
bg_w, bg_h = bg.size
# Creates a new empty image, RGB mode, and size 1000 by 1000
new_im = Image.new('RGB', (1000,1000))
# The width and height of the new image
w, h = new_im.size
# Iterate through a grid, to place the background tile
for i in xrange(0, w, bg_w):
for j in xrange(0, h, bg_h):
# Change brightness of the images, just to emphasise they are unique copies
bg = Image.eval(bg, lambda x: x+(i+j)/1000)
#paste the image at location i, j:
new_im.paste(bg, (i, j))
new_im.show()
产生这个:
或者删除 Image.eval()
行:
