二、api文档

1. PyMuPDF (pdf转图片) https://pymupdf.readthedocs.io/en/latest/index.html
2. pdf2docx (pdf转word) https://dothinking.github.io/pdf2docx/installation.html
3. doc2pdf (word 转 pdf) https://pypi.org/project/docx2pdf/

三、使用

1.pdf转图片

pip install pymupdf

import fitz
#打开pdf
pdf = fitz.open(<pdf_path_dir>)
#遍历pdf
for page in pdf.pages(0, pdf.page_count, 1):
	#创建像素图
    pix = page.get_pixmap(matrix=fitz.Matrix(a, b))
    #保存
    pix.save(f"{out}page-%i.png" % page.number)

2.pdf转word

pip install pdf2docx

from pdf2docx import Converter
cv = Converter(<pdf_path_dir>)
cv.convert(out)      # all pages by default
cv.close()

3.doc2pdf

pip install docx2pdf

from docx2pdf import convert
convert(<doc_path_dir>, <pdf_path_dir>)
