如何使用alpha_composite组合4张图片？

Question

我遇到并发出我收到的错误消息，当一切看起来都正常时，我的图像不匹配。我已经搜索了整个互联网，知道如何做至少2个图像，但4个图像是不工作的。

下面是我的代码：

#### Generate Images    
for item in all_images:

im1 = Image.open(f'./trait-layers/backgrounds/{background_files[item["Background"]]}.jpg').convert('RGBA')
im2 = Image.open(f'./trait-layers/elephants/{elephant_files[item["Elephant"]]}.png').convert('RGBA')
im3 = Image.open(f'./trait-layers/hats/{hat_files[item["Hat"]]}.png').convert('RGBA')
im4 = Image.open(f'./trait-layers/smoke/{smoke_files[item["Smoke"]]}.png').convert('RGBA')

#Create each composite
com1 = Image.alpha_composite(im1, im2)
com2 = Image.alpha_composite(com1, im3)
com3 = Image.alpha_composite(com2, im4)



#Convert to RGB
rgb_im = com3.convert('RGB')
file_name = str(item["tokenId"]) + ".png"
rgb_im.save("./images/" + file_name)

我收到这个错误消息：

  ValueError: images do not match

     12     com3 = Image.alpha_composite(com2, im4)

您需要确保所有图像文件都是相同的
