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)
