pdf合并及页面删除、排序和旋转

分割及合并pdf

利用pypdf2分割pdf
from PyPDF2 import PdfFileReader,PdfFileWrite
pdf_reader=PdfFileReader(‘XXX.pdf’)
for page in range(pdf_reader.getNumPages()):
pdf_writer=PdfFileWriter()
pdf_writer.addPage(pdf_reader.getPage(page))
with open(’./分割后的PDF文件/XXX{}.pdf’.format(page),‘wb’) as out:
#确保文件夹已经创建
pdf_writer.writer(out)

利用pypdf2合并pdf
pdf_writer=PdfFileWriter()
for page in range(16):
pdf_reader=PdfFileReader(’./分割后的PDF文件/XXX{}.pdf’.format(page))
for page in range(pdf_reder.getNumPages()):
pdf_writer.addPage(pdf_reader.getPage(page))
with open(‘merged.pdf’,‘wb’) as out:
pdf_writer.writer(out)

旋转及排序
pdf_reader=PdfFileReader(‘XXX.pdf’)
pdf_writer=PdfFileWriter()
page=pdf_reader.getPage(0).rotateClockwise(90)
#.rotateClockwise(90的倍数)顺时针旋转90度
pdf_writer.addPage(page)
page=pdf_reader.getPage(0).rotateCounterClockwise(90)
#.rotateCounterClockwise(90的倍数)逆时针旋转90度
pdf_writer.addPage(page)
with open(‘rotated.pdf’,‘wb’) as out:
pdf_writer.writer(out)

排序
pdf_reader=PdfFileReader(‘XXX.pdf’)
pdf_writer=PdfFileWriter()
for page in range(pdf_reader.getNumPages() -1，-1，-1): #此处为倒序排列
pdf_writer.addPage(pdf_reader.getPage(page))
with open(‘reordered.pdf’,‘wb’) as out:
pdf_writer.writer(out)
