PIL如何在1幅新圖像上調整大小，分割和共享圖像？

Question

我試圖製作一個popart圖像（顯示在下面），但我不知道如何調整圖像大小，然後將其分割爲1個大圖像上共享的9個較小圖像，保持與原始大小相同一。 這裏的腳本（這使得POPART是def Popart()腳本的一部分：

main.mainloop() 

這是我想要做什麼：

出於這種（我知道的顏色是不是很完美）：

我也知道，我喜歡用簡單的z變量，我應該例如Original_Image使用。我只是想知道如何調整它，並把它分解，同時保持圖像的原始大小。

Answer 1

我有9個不同的圖像，每個圖像都命名爲result0.png; result1.png; result2.png;...，所以我創建了一個包含這些圖像的列表，然後我用for循環一次打開它們，然後根據它們的位置調整它們的大小，創建的圖像。 這裏是代碼：

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")
