解壓.docx文件實現提取圖片
前言
.docx文件其實也就是一個壓縮文件,當我們將一個.docx文件直接解壓后可以看到如下目錄
其中我們要找的圖片就在word/media目錄內,如圖
所以,要提取word內的圖片就需要將.docx文件解壓,再從media文件內取得圖片,然后將解壓后的文件刪除
代碼實現
import
os
import
shutil
import
zipfile
def
get_pictures(word_path, result_path):
"""
獲取word內的所有圖片
:param word_path: word文件
:param result_path: 結果目錄,無需手動創建
:return: None or generator,None:word內沒有圖片,generator:每個圖片的路徑
"""
tmp_path
=
f
'{os.path.splitext(word_path)[0]}'
# 拷貝源文件后重命名再解壓
splitext
=
os.path.splitext(word_path)
zip_path
=
shutil.copy(word_path, f
'{splitext[0]}_new{splitext[1]}'
)
with zipfile.ZipFile(zip_path,
'r'
) as f:
for
file
in
f.namelist():
f.extract(
file
, tmp_path)
os.remove(zip_path)
# 注:word圖片在zip文件內的word/media目錄下
pic_path
=
os.path.join(tmp_path,
'word/media'
)
if
not
os.path.exists(pic_path):
shutil.rmtree(tmp_path)
return
'no pictures found'
pictures
=
os.listdir(pic_path)
if
not
os.path.exists(result_path):
os.makedirs(result_path)
for
picture
in
pictures:
# 根據word的文件名生成圖片的名稱
word_name
=
os.path.splitext(word_path)[
0
]
if
os.sep
in
word_name:
new_name
=
word_name.split(
'\\'
)[
-
1
]
else
:
new_name
=
word_name.split(
'/'
)[
-
1
]
picture_name
=
f
'{new_name}_{picture}'
shutil.copy(os.path.join(pic_path, picture), os.path.join(result_path, picture_name))
shutil.rmtree(tmp_path)
return
(os.path.join(result_path, pic)
for
pic
in
os.listdir(result_path))

word_path可以支持所有類型路徑,如
p
=
r
"C:\Users\Desktop\test\小說.docx"
p1
=
"C:/Users/Desktop/test/小說.docx"
p2
=
"C:\\Users\\Desktop\\test\\小說.docx"

利用三方庫docx實現圖片提取(推薦)
import
docx
import
os, re
def
get_pictures(word_path, result_path):
"""

:param word_path: word路徑
:param result_path: 結果路徑
:return:
"""
doc
=
docx.Document(word_path)
dict_rel
=
doc.part._rels
for
rel
in
dict_rel:
rel
=
dict_rel[rel]
if
"image"
in
rel.target_ref:
if
not
os.path.exists(result_path):
os.makedirs(result_path)
img_name
=
re.findall(
"/(.*)"
, rel.target_ref)[
0
]
word_name
=
os.path.splitext(word_path)[
0
]
if
os.sep
in
word_name:
new_name
=
word_name.split(
'\\'
)[
-
1
]
else
:
new_name
=
word_name.split(
'/'
)[
-
1
]
img_name
=
f
'{new_name}_{img_name}'
with
open
(f
'{result_path}/{img_name}'
,
"wb"
) as f:
f.write(rel.target_part.blob)
