Those two do not give the same results: from PyPDF2 import PdfFileReader, PdfFileWriter, Transformation
for separated in [True, False]:
reader_base = PdfFileReader("labeled-edges-center-image.pdf")
page_base = reader_base.pages[0]
reader = PdfFileReader("box.pdf")
page_box = reader.pages[0]
# Apply the transformation: Be aware, that this is an in-place operation
op = Transformation().scale(2).rotate(45)
if separated:
page_box.add_transformation(op, expand=True)
page_base.mergePage(page_box, expand=True)
else:
page_base.mergeTransformedPage(page_box, op, expand=False)
# Write the result back
writer = PdfFileWriter()
writer.addPage(page_base)
with open(f"merged-separeted-{separated}.pdf", "wb") as fp:
writer.write(fp)Something seems to be wrong about the mediabox / trimbox |

The 2.0.0 release of PyPDF2 includes three core changes: 1. Dropping support for Python 3.5 and older. 2. Introducing type annotations. 3. Interface changes, mostly to have PEP8-compliant names We introduced a [deprecation process](#930) that hopefully helps users to avoid unexpected breaking changes. Breaking Changes(DEP): - PyPDF2 2.0 requires Python 3.6+. Python 2.7 and 3.5 support were dropped. - PdfFileReader: The "warndest" parameter was removed - PdfFileReader and PdfFileMerger no longer have the `overwriteWarnings` parameter. The new behavior is `overwriteWarnings=False`. - merger: OutlinesObject was removed without replacement. - merger.py ➔ _merger.py: You must import PdfFileMerger from PyPDF2 directly. - utils: * `ConvertFunctionsToVirtualList` was removed * `formatWarning` was removed * `isInt(obj)`: Use `instance(obj, int)` instead * `u_(s)`: Use `s` directly * `chr_(c)`: Use `chr(c)` instead * `barray(b)`: Use `bytearray(b)` instead * `isBytes(b)`: Use `instance(b, type(bytes()))` instead * `xrange_fn`: Use `range` instead * `string_type`: Use `str` instead * `isString(s)`: Use `instance(s, str)` instead * `_basestring`: Use `str` instead * All Exceptions are now in `PyPDF2.errors`: - PageSizeNotDefinedError - PdfReadError - PdfReadWarning - PyPdfError - `PyPDF2.pdf` (the `pdf` module) no longer exists. The contents were moved with the library. You should most likely import directly from `PyPDF2` instead. The `RectangleObject` is in `PyPDF2.generic`. - The `Resources`, `Scripts`, and `Tests` will no longer be part of the distribution files on PyPI. This should have little to no impact on most people. The `Tests` are renamed to `tests`, the `Resources` are renamed to `resources`. Both are still in the git repository. The `Scripts` are now in https://github.com/py-pdf/cpdf. `Sample_Code` was moved to the `docs`. For a full list of deprecated functions, please see the changelog of version 1.28.0. New Features (ENH): - Improve space setting for text extraction (#922) - Allow setting the decryption password in PdfReader.__init__ (#920) - Add Page.add_transformation (#883) Bug Fixes (BUG): - Fix error adding transformation to page without /Contents (#908) Robustness (ROB): - Cope with invalid length in streams (#861) Documentation (DOC): - Fix style of 1.25 and 1.27 patch notes (#927) - Transformation (#907) Developer Experience (DEV): - Create flake8 config file (#916) - Use relative imports (#875) Maintenance (MAINT): - Use Python 3.6 language features (#849) - Add wrapper function for PendingDeprecationWarnings (#928) - Use new PEP8 compliant names (#884) - Explicitly represent transformation matrix (#878) - Inline PAGE_RANGE_HELP string (#874) - Remove unnecessary generics imports (#873) - Remove star imports (#865) - merger.py ➔ _merger.py (#864) - Type annotations for all functions/methods (#854) - Add initial type support with mypy (#853) Testing (TST): - Regression test for xmp_metadata converter (#923) - Checkout submodule sample-files for benchmark - Add text extracting performance benchmark - Use new PyPDF2 API in benchmark (#902) - Make test suite fail for uncaught warnings (#892) - Remove -OO testrun from CI (#901) - Improve tests for convert_to_int (#899) Full Changelog: 1.28.4...2.0.0
