Batch replace tables in Word with pictures and save

之前我在《将WordThe table in the picture is copied to WeChat and sent》Shared how to assignwordThe table in is pasted as a picture,参考：https://xxmdmst.blog.csdn.net/article/details/125999841

Today, a group of friends asked how to make oneWordReplace all tables with pictures,Please see my complete code below：

import os
import win32com.client as win32
from io import BytesIO
import win32clipboard
from PIL import Image, ImageGrab, ImageChops


def crop_image(im, backgroud_color=(255, 255, 255)):
    '''Crop the margins of the image and fill the alpha channel with a white background,作者：小小明'''
    bg = Image.new(mode='RGBA', size=im.size)
    bbox = ImageChops.difference(im, bg).getbbox()
    if bbox:
        im = im.crop(bbox)
    img = Image.new('RGB', im.size, backgroud_color)
    img.paste(im, (0, 0, *im.size), im)
    return img


def write_img2clipboard(img):
    """Write the specified picture to the clipboard,作者：小小明"""
    win32clipboard.OpenClipboard()
    try:
        win32clipboard.EmptyClipboard()
        out = BytesIO()
        img.save(out, "BMP")
        # BMP图片有14字节的header,need to be removed
        data = out.getvalue()[14:]
        # DIB: 设备无关位图(device-independent bitmap)
        win32clipboard.SetClipboardData(win32clipboard.CF_DIB, data)
    finally:
        win32clipboard.CloseClipboard()


def process_clipboard_pic(backgroud_color=(255, 255, 255)):
    """Blank the clipping edges of the image in the clipboard and add a background color to the transparent parts,作者：小小明"""
    img = ImageGrab.grabclipboard()
    img = crop_image(img, backgroud_color)
    write_img2clipboard(img)
    return img


# 获取正在运行的Word应用
wordApp = win32.GetActiveObject("Word.Application")
# 获取当前激活的word文档
doc = wordApp.ActiveDocument
# Iterate over all table objects
for t in doc.Tables:
    t.Select()
    wordApp.Selection.CopyAsPicture()
    img = process_clipboard_pic()
# display(img)
    t.Delete()
    wordApp.Selection.Paste()

# 另存为word文件
doc.SaveAs2(os.path.abspath("替换图片.docx"))

As long as we open the ones that need to be replaced in batchesWord文件,然后执行上述代码,You can see the effect before and after running.

打开的Word文档：

运行上述代码后：

The table can be replaced smoothly,If you need to change the background color of the picture,可以向process_clipboard_pic()Pass in the specified color value,Such as bean paste color background：

process_clipboard_pic(backgroud_color=(204, 232, 207))

There are also some problems when a table grows to span multiple pages,The program can only take screenshots to the content of the first page,This requires that long tables must be manually split in advance.

我使用WPS's split by row feature：

Run the above code again after manually splitting the table,The complete table image has been successfully captured：

注意：Save as if not neededWord文档,可以直接保存,The last line of code can be modified as follows：

doc.Save()

Of course you can also delete the last line of code about saving,Manually review the modification results,Decide whether to save or save as.

It is recommended to save as a backup of the original document as well,In case which form is too long and forget to split it？
