问题描述
我找到了一些Python2代码来从Excel文件中提取图像.
I found some Python2 code to extract images from Excel files.
我有一个非常基本的问题:我应该在哪里指定目标excel文件的路径?
I have a very fundamental question: Where shall I specify the path of my target excel file?
还是仅对打开的活动Excel文件起作用?
Or does it only work with an active opened Excel file?
import win32com.client # Need pywin32 from pip
from PIL import ImageGrab # Need PIL as well
import os
excel = win32com.client.Dispatch("Excel.Application")
workbook = excel.ActiveWorkbook
wb_folder = workbook.Path
wb_name = workbook.Name
wb_path = os.path.join(wb_folder, wb_name)
#print "Extracting images from %s" % wb_path
print("Extracting images from", wb_path)
image_no = 0
for sheet in workbook.Worksheets:
for n, shape in enumerate(sheet.Shapes):
if shape.Name.startswith("Picture"):
# Some debug output for console
image_no += 1
print("---- Image No. %07i ----", image_no)
# Sequence number the pictures, if there's more than one
num = "" if n == 0 else "_%03i" % n
filename = sheet.Name + num + ".jpg"
file_path = os.path.join (wb_folder, filename)
#print "Saving as %s" % file_path # Debug output
print('Saving as ', file_path)
shape.Copy() # Copies from Excel to Windows clipboard
# Use PIL (python imaging library) to save from Windows clipboard
# to a file
image = ImageGrab.grabclipboard()
image.save(file_path,'jpeg')
推荐答案
您可以像这样从现有Excel文件中抓取图像:
You can grab images from existing Excel file like this:
from PIL import ImageGrab
import win32com.client as win32
excel = win32.gencache.EnsureDispatch('Excel.Application')
workbook = excel.Workbooks.Open(r'C:\Users\file.xlsx')
for sheet in workbook.Worksheets:
for i, shape in enumerate(sheet.Shapes):
if shape.Name.startswith('Picture'):
shape.Copy()
image = ImageGrab.grabclipboard()
image.save('{}.jpg'.format(i+1), 'jpeg')
