individual_pages must contain a list of 925 individual pages
Actual:
individual_pages has only 1 element which same as the multi_page_image but with a temp filename.
I noticed that this is happening with pdfs having the producer given in the output. Rest of the pdfs I tested have a different producer and its working for them.
OS details:
only tried testing this with debian 11 docker, ubuntu docker.
It's because your image doesn't split neatly into pages. You have an image height of 1622346 and a page height of 1650, but 1622346 / 1650 is 988.24, not 925. I would guess that one of the pages in your document is a different size.
You will probably have to process this one page at a time, perhaps (untested):
Is there no other workaround other than the looping method? Because, the loop method itself was my first approach. But for some reason the azure function that I hosted this code errored out with code 137 after 6 or 7 iterations. And that is happening with equal sized pages also but they are non-digital (scanned image pdfs).
You could open a page at a time and try to find which pages differ in size.
You could also try opening pages in sequential mode, and using a loop rather than a list comprehension. And it depends what you plan to do with the pages once you've loaded them.
Hi @jcupitt,
