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：
