python - 在 Python 中合并图像

Question

如果两个图像大小相等，我正在尝试将它们合并在一起。有人可以帮我吗？这就是我到目前为止所得到的......

import PIL
from PIL import Image as img
x = img.open('index.jpg')
w1, h1 = x.size
print('Image 1 =',w1,'x',h1)

y = img.open('index2.jpg')
w2, h2 = y.size
print('Image 2 =',w1,'x',h1)

if x.size == y.size :
    print('Their size is equal.')
    height = max(h1,h2)
    width = w1 + w2
    z = img.new("RGB",(width,height))
    z.paste(x)
    #z.paste(y)
    z.show()

else:
    print('Their size is not equal.')

如何将第二张图像粘贴到第一张图像旁边？

Answer 1

.paste(..)函数允许您指定 box 参数来指定位置。

因此，您可以粘贴第二张图像:

import PIL
from PIL import Image as img
x = img.open('img1.jpg')
w1, h1 = x.size
print('Image 1 =',w1,'x',h1)

y = img.open('img2.jpg')
w2, h2 = y.size
print('Image 2 =',w1,'x',h1)

if x.size == y.size :
    print('Their size is equal.')
    z = img.new("RGB",(w1 + w2,h1))
    z.paste(x)
    z.paste(y<b>, box=(w1, 0)</b>)
    z.show()
else:
    print('Their size is not equal.')

请注意，由于尺寸相等，因此高度仅为 h1。

您可以放宽尺寸的限制，因为如果高度相同，这也可以工作，只是如果宽度不同，图像不会分成两半:

import PIL
from PIL import Image as img
x = img.open('img1.jpg')
w1, h1 = x.size
print('Image 1 =',w1,'x',h1)

y = img.open('img2.jpg')
w2, h2 = y.size
print('Image 2 =',w1,'x',h1)

if <b>h1 == h2</b>:
    print('Their size is equal.')
    z = img.new("RGB",(w1 + w2,h1))
    z.paste(x)
    z.paste(y, box=(w1, 0))
    z.show()
else:
    print('Their size is not equal.')
