python转换doc到pdf
利用python将图片版PDF转文字版PDF图片版pdf无法复制,转化成文字版的pdf后使用更方便.
我们需要用到python3.6,pypdf2,ghostscript,pythonmagick,百度文字识别服务和pdfkit.
安装
安装python3.6 略
安装ghostscript
https://ghostscript.com/download/gsdnld.html
安装wkhtmltopdf
https://wkhtmltopdf.org/downloads.html
pip安装pypdf2,ghostscript,baidu-aip,pdfkit
|
pip install pypdf2 pip install ghostscript pip install baidu - aip pip install pdfkit |
pip安装pythonmagick
https://www.lfd.uci.edu/~gohlke/pythonlibs/
|
cd 下载目录 pip install pythonmagick‑ 0.9 . 13 ‑cp36‑cp36m‑win_amd64.whl |
pypdf2用于拆分和合并pdf
示例代码如下:
|
#导入pdffilereader和pdffilewriter from pypdf2 import pdffilereader, pdffilewriter #获取一个pdf对象 pdf_input = pdffilereader( open (r 'pdf路径' , 'rb' )) #获取pdf页数 page_count = pdf_input.getnumpages() #获取pdf第四页的内容 page = pdf_input.getpage( 3 ) page[ '/contents' ] #获取一个pdfwriter对象 pdf_output = pdffilewriter() # 将一个 pageobject 加入到 pdffilewriter 中 pdf_output.addpage(page) #把新pdf保存 pdf_output.write( open (r '新pdf路径' , 'wb' )) |
pythonmagick用于将单页pdf转化为jpg
百度云-文字识别-python sdk
每天有500次免费的识别
示例代码如下:
|
#导入baidu-aip from aip import aipocr #https://console.bce.baidu.com/#/index/overview #产品服务->人工智能->文字识别->创建应用 #获取以下三个值 app_id = '??' api_key = '??' secret_key = '?? ' #新建一个aipocr client = aipocr(app_id, api_key, secret_key) #读取本地图片的函数 def get_file_content(filepath): with open (filepath, 'rb' ) as fp: return fp.read() #读取本地图片 image = get_file_content( 'p1.jpg' ) #可选参数 options = {} options[ "language_type" ] = "chn_eng" options[ "detect_direction" ] = "true" options[ "detect_language" ] = "true" options[ "probability" ] = "true" #通用文字识别 client.basicgeneral(image, options) #读取网络图片 url = "https://note.youdao.com/yws/public/resource/1577071c1ffa2b6bf4e238ef6dbcfbf5/xmlnote/e5a19bedfeba4879b217c5bbf53b0245/22138" #可选参数 options = {} options[ "language_type" ] = "chn_eng" options[ "detect_direction" ] = "true" options[ "detect_language" ] = "true" options[ "probability" ] = "true" #通用文字识别 client.basicgeneralurl(url, options) #读取本地表格图片的函数 def get_file_content(filepath): with open (filepath, 'rb' ) as fp: return fp.read() #读取本地表格图片 image = get_file_content( 'p2.jpg' ) #可选参数 options = {} options[ "language_type" ] = "chn_eng" options[ "detect_direction" ] = "true" options[ "detect_language" ] = "true" options[ "probability" ] = "true" #通用文字识别 client.basicgeneral(image, options) #读取表格分割效果较差! |
pdfkit用于利用字符串生成pdf
示例代码如下:
|
#pdfkit安装位置设置 path_wk = r 'pdfkit安装位置设置' pdfkit_config = pdfkit.configuration(wkhtmltopdf = path_wk) #pdfkit参数 pdfkit_options = { 'encoding' : 'utf-8' ,} #制作pdf pdfkit.from_string(( 'string' ), 'd:\test.pdf' ,configuration = pdfkit_config,options = pdfkit_options) |

#导入所需包 #os,操作文件和路径 import os #ghostscript,代码简化 import ghostscript #pypdf2,拆分pdf from pypdf2 import pdffilereader, pdffilewriter #pythonmagick,单页pdf转图片 from pythonmagick import image #baidu-aip,百度文字识别 from aip import aipocr #pdfkit,字符串制作pdf import pdfkit #参数 path = '??' pdfname = '??' dpi = '85' #https://console.bce.baidu.com/#/index/overview #产品服务->人工智能->文字识别->创建应用 #获取以下三个值 app_id = '??' api_key = '??' secret_key = '??
