一、将 doc 转为 pdf

1、install 依赖

pip install pywin32

 

2、直接调用win32com接口打开文件，另存为pdf。SaveAs中的参数17代表村委pdf格式，完了关闭文件，关闭word。

 1     def doc2pdf(self):
 2         try:
 3             w = Dispatch("Word.Application")
 4             doc = w.Documents.Open(self.docPath, ReadOnly=1)
 5             doc.SaveAs(self.pdfPath, 17)
 6         except:
 7             traceback.print_exc()
 8         finally:
 9             doc.Close()
10             w.Quit()
11         self.checkFile(self.pdfPath, \'pdf\')

以下为文件格式对应表

wdFormatDocument = 0
wdFormatDocument97 = 0
wdFormatDocumentDefault = 16
wdFormatDOSText = 4
wdFormatDOSTextLineBreaks = 5
wdFormatEncodedText = 7
wdFormatFilteredHTML = 10
wdFormatFlatXML = 19
wdFormatFlatXMLMacroEnabled = 20
wdFormatFlatXMLTemplate = 21
wdFormatFlatXMLTemplateMacroEnabled = 22
wdFormatHTML = 8
wdFormatPDF = 17
wdFormatRTF = 6
wdFormatTemplate = 1
wdFormatTemplate97 = 1
wdFormatText = 2
wdFormatTextLineBreaks = 3
wdFormatUnicodeText = 7
wdFormatWebArchive = 9
wdFormatXML = 11
wdFormatXMLDocument = 12
wdFormatXMLDocumentMacroEnabled = 13
wdFormatXMLTemplate = 14
wdFormatXMLTemplateMacroEnabled = 15
wdFormatXPS = 18

　　

 

二、将pdf转为图片

1、install 依赖

1.1、pip isntall PyMuPDF

 

1.2、Windows安装配置poppler
Windows用户必须为Windows安装poppler (http://blog.alivate.com.au/poppler-windows/)，然后将bin/文件夹添加到PATH（开始>输入env>编辑系统环境变量>环境变量...>系统变量>Path）
安装完poppler需重启系统后生效。
 
2、将pdf转为图片
 1     def pdf2image(self):
 2         # 建立图片文件夹
 3         if not os.path.exists(self.imgFold):
 4             os.mkdir(self.imgFold)
 5 
 6         # 转存图片
 7         pages = fitz.open(self.pdfPath)
 8         for page in pages:
 9             imgPath = os.path.join(self.imgFold, str(page.number)+\'.jpg\')
10             pix = page.getPixmap()
11             pix.writeImage(imgPath)
12         self.checkFile(imgPath, \'last img\')

 

三、直接将word转为图片

方法：结合1,2

代码如下：

 1 \'\'\'
