我做了一個合并圖像的程序，我想升級這個程序，使圖像的總高度應小于 2450 像素，并保存每個合并的圖像。import osimport tkinter.ttk as ttkimport tkinter.messagebox as msgboxfrom tkinter import * # __all__from tkinter import filedialogfrom PIL import Image# add filedef add_file():files = filedialog.askopenfilenames(title="??? ??? ?????", \ filetypes =(('jpg ??', '*.jpg'), ('?? ??', '*.*')), \ initialdir='D:/jh/??/????/??? ??? ??? ????/image') # file list that user can selectfor file in files: list_file.insert(END, file)# file frame(file add, selected file delete)file_frame = Frame(root)file_frame.pack(fill='x', padx=5, pady=5)btn_add_file = Button(file_frame, padx=5, pady=5, width=12, text='????', command=add_file)btn_add_file.pack(side='left')btn_del_file = Button(file_frame, padx=5, pady=5, width=12, text='????', command=del_file)btn_del_file.pack(side='right')# list framelist_frame = Frame(root)list_frame.pack(fill='both', padx=5, pady=5)scrollbar = Scrollbar(list_frame)scrollbar.pack(side='right', fill='y')list_file = Listbox(list_frame, selectmode='extended', height=12, yscrollcommand=scrollbar.set)list_file.pack(side='left', fill='both', expand=True)scrollbar.config(command=list_file.yview)..... dest_path = os.path.join(txt_dest_path.get(), txt_file.get()) # txt_file get values after to input entry for file name. ex) desk result_img.save(dest_path) #save result_img to dest_path msgbox.showinfo('??', '??? ???????.') 在這個編碼中，list_file 是 Listbox 并且有幾個相同寬度但不同高度的圖像。我想合并這張圖片，但合并后的圖片高度不能超過 2450 像素。例如，list_file 是 a0、a1、a2、a3、a4、a5、a6。list_file 中圖片的高度為 200, 1500, 2400, 100, 300, 500, 1600。那么 list_file 應該是 a0 <-(a0+a1), a1<-(a2), a2<-(a3, a4, a5) , a3<-(a6) [1700, 2400, 900, 1600]我想獲取條目值并保存 list_file 的每個圖像。例如輸入值為desk，文件名應為desk 001.jpg、desk 002.jpg、desk 003.jpg、desk 004.jpg等。

您可以使用Image.new(...)創建合并圖像，然后使用Image.paste(...)將所需圖像復制到合并圖像中：
def merge_images(imagelist, width, height, seqno):
if imagelist:
# create the merged image
merged_image = Image.new('RGB', (width, height), (0,0,0))
y = 0
for image in imagelist:
merged_image.paste(image, (0, y))
y += image.height
# save the merged image
dest_path = os.path.join(txt_dest_path.get(), 'desk%03d.jpg' % seqno)
merged_image.save(dest_path)
seqno += 1
return seqno
def merge():
MAX_HEIGHT = 2450
merge_list = []
height = 0
width = None
seqno = 1
for file in list_file.get(0, 'end'):
image = Image.open(file)
if width is None:
width = image.width
if height+image.height <= MAX_HEIGHT:
merge_list.append(image)
height += image.height
else:
seqno = merge_images(merge_list, width, height, seqno)
merge_list = [image]
height = image.height
merge_images(merge_list, width, height, seqno)
