Format specifier warning in pdfrenderer.cpp about tesseract HOT 5 CLOSED

it seems that the z prefix isn't defined in MS Visual Studio size specification.

from tesseract.

I'm the author of this code. I'd prefer to keep using size_t for this number since PDF files can be really big (although, this code will break for other reasons once we get larger than 10 gigabytes). Not sure what to do here to make all platforms happy.

OK--since this warning isn't indicative of a larger problem, and there's no clear solution for muting this warning across the board, let's close this issue.

from tesseract.

That's not a solution. It's a bug, not a compiler warning which must be muted.

You will get a wrong results on little endian platforms when sizeof(long) != sizeof(size_t).
On big endian platforms the result is wrong when sizeof(long) > sizeof(size_t).

Adding a type cast would help: (long)len

Even better would be replacing "%ld" by "%lu" and using this: (unsigned long)len

It seems that @stweil solved this with this commit:
