python操作PDF------旋轉及排序pdf

# 安裝 pip install pypdf2
from PyPDF2 import PdfFileReader, PdfFileWriter


# 用pypdf2旋轉PDF某一頁
pdf_reader = PdfFileReader('基於python的網頁爬蟲.pdf')
pdf_writer = PdfFileWriter()
# 順時針旋轉90度  90的倍數
page = pdf_reader.getPage(0).rotateClockwise(90)
pdf_writer.addPage(page)
# 逆時針旋轉90度  90的倍數
page = pdf_reader.getPage(1).rotateCounterClockwise(90)
pdf_writer.addPage(page)
with open('rotated.pdf', 'wb') as f:
    pdf_writer.write(f)


# 排序pdf頁面  此處例子為倒序排序
pdf_reader = PdfFileReader('基於python的網頁爬蟲.pdf')
pdf_writer = PdfFileWriter()
for page in range(pdf_reader.getNumPages()-1, -1, -1):
    pdf_writer.addPage(pdf_reader.getPage(page))
with open('reordered.pdf', 'wb') as f:
    pdf_writer.write(f)
