PIL 如何在 1 张新图像上调整大小、拆分和共享图像？

Question

我正在尝试制作 popart 图像（如下所示），但我不知道如何调整图像大小，然后将其拆分为 9 个小图像共享在 1 个大图像上，保持相同大小作为原来的。这是脚本（制作 popart 的脚本部分是 def Popart():

这是我想要做的：

出自这个（我知道颜色不是很完美）：

我也知道我在应该使用 Original_Image 的地方使用像 z 这样的简单变量。我只是想知道如何在保持原始图像大小的同时调整它的大小和拆分它。

Answer 1

我有 9 张不同的图片，每张都命名为 result0.png; result1.png; result2.png;...，所以我创建了一个包含这些图片的列表，然后我用 for 循环一次打开它们，然后我调整它们和每一张的大小它们的位置取决于它们在新创建的图像中的位置。这是代码：

 Img1=[None]*9
    pixels1=[None]*9
    Imaz=Image.new("RGB",(basewidth*3,hsize*3))
    pixels=Imaz.load()
    for i in range(9):
        Img1[i]=Image.open(''+dir_path+'\PopArt\Resized Images\resized_image'+str(i)+'.png')
        pixels1[i]=Img1[i].load()


    for x in range(0,basewidth):
        for y in range(0,hsize):
            pixels[x,y]=pixels1[0][x,y]
        for y in range(hsize,hsize*2):
            pixels[x,y]=pixels1[1][x,y-hsize]
        for y in range(hsize*2,hsize*3):
            pixels[x,y]=pixels1[2][x,y-hsize*2]

    for x in range(basewidth,basewidth*2):
        for y in range(0,hsize):
            pixels[x,y]=pixels1[3][x-basewidth,y]
        for y in range(hsize,hsize*2):
            pixels[x,y]=pixels1[4][x-basewidth,y-hsize]
        for y in range(hsize*2,hsize*3):
            pixels[x,y]=pixels1[5][x-basewidth,y-hsize*2]

    for x in range(basewidth*2,basewidth*3):
        for y in range(0,hsize):
            pixels[x,y]=pixels1[6][x-basewidth*2,y]
        for y in range(hsize,hsize*2):
            pixels[x,y]=pixels1[7][x-basewidth*2,y-hsize]
        for y in range(hsize*2,hsize*3):
            pixels[x,y]=pixels1[8][x-basewidth*2,y-hsize*2]
    Imaz = Imaz.resize((size[0] , size[1] ), PIL.Image.ANTIALIAS)
    Imaz.save(""+dir_path+"\PopArt\Result Image\result.png")

PIL 如何在 1 张新图像上调整大小、拆分和共享图像？
