page1.merge_page(page2, expand=True) doesn't seem to work #1035
Description
I am trying to merge two PDF page into one page. One thing is, those Pdf are kinda long (3 meters each, so 6 meters in the end)
When I try to merge those two pdf, the second PDF doesn't write past a certain area.
Code
import PyPDF2 as pdf
from PyPDF2.generic import RectangleObject
from PyPDF2 import PageObject, PdfReader, PdfWriter, Transformation
reader = PdfReader("E036_000_Tralongpdf2.0.pdf")
page = reader.pages[0]
x1, y1, x2, y2 = page.cropbox
op1 = Transformation().translate(tx=0, ty=0)
page.add_transformation(op1)
reader2 = PdfReader("E036_000_Tralongpdf1.0.pdf")
page2 = reader2.pages[0]
x21, y21, x22, y22 = page2.cropbox
assert x21 == 0
assert y21 == 0
op2 = Transformation().translate(tx=0, ty=y22 - 2000) # ty=y2)
page2.add_transformation(op2)
page3 = PageObject.createBlankPage(reader, width=845, height=19000)
rect = RectangleObject((0.0, 0.0, 845.0, 25000.0))
print(page3.mediabox)
page3.cropbox = rect
page3.merge_page(page2)
page3.merge_page(page)
writer = PdfWriter()
page3.trimBox = rect
print(page3.cropbox)
writer.add_page(page3)
with open("output.pdf", "wb") as fp:
writer.write(fp)Environment
