Question

我尝试使用PyPDF2合并到python中的pdf文件。
问题是文件大小。
那么有没有其他方法来合并没有文件大小限制和内存问题的文件？

文件大小1 = 900MB
文件大小2 = 300MB

我的理解。有没有办法只加载第一个pdf的最后一页并附上第二个pdf？

我的代码：

from PyPDF2 import PdfFileMerger, PdfFileReader

merger = PdfFileMerger()

filename1 = 'document-output3.pdf'
filename2 = 'file1.pdf'

merger.append(PdfFileReader(open(filename1, 'rb')))
merger.append(PdfFileReader(open(filename2, 'rb')))

merger.write("document-output3.pdf")
