Broken pages in saved pdf document. about pymupdf HOT 2 CLOSED

It makes sense. Thank You. I was able to isolate new example with pages I can share, which break file with one save. I’m marking this issue as closed and I will make new one in a minute to separate cases of multiple saves from broken pages.

If you repeat saving a document with compression options, please be aware that this first changes the document in memory - before it is saved to disk.

What you seem to detect is that multiple executions of the same duplication detector (garbage=4) in a row may finally run into an error.
As it appears at the moment, the problem only happens under this eccentric programming behavior: why would anyone execute 4 saves in a row with the same options! It is difficult to assign priority to an error which only exhibits under such circumstances.

It seems that you want to achieve the best compression effect when saving. I suggest to use doc.ez_save(filename, garbage=4) (1 time only). This will do the best duplicates detection in conjunction with optimum compression.

Please try to reproduce the problem when using a reasonable programming style.
