Paul Ingemi	505344f83e	Add Windows support for paths containing wildcards "*" and "?" ... Img2pdf accepts paths containing wildcards such as *.jpg to efficiently refer to multiple input files that match the wildcard expression. Under POSIX environments the command line shell is expected to perform this expansion, however Windows requires the command line utility itself to expand the wildcard expression. Ideally this would be performed by argparse as described in this draft PEP: https://mail.python.org/pipermail/python-ideas/2015-August/035244.html Since argparse doesn't do it, this commit performs expansion directly. Some implementation notes: - Wildcard characters "*" and "?" are not valid in Windows filenames - Code doesn't support bracket wildcards such as [0-3] on Windows since they are valid filename characters - Due to expansion, the images list collected by argparse may contain sub-lists. Code uses chain.from_iterable to create a flat list. - Paths that refer to non-existant files raise an error message, while wildcards that match no files are silently ignored.	2020-10-05 10:28:08 +02:00

James R. Barlow	a8269391e9	Implement /UserUnit scaling to support oversized PDFs ... The original PDF specification supported a maximum of 200x200" pages or 14400 PDF units. In PDF 1.6 rather than remove this limitation, Adobe added the /UserUnit field for pages, which allows one to specify the scaling that should be applied for user-facing numbers, while keeping the internal limit of 14400 units. Many real-world designs are larger than 200" in one direction. One example is tractor feed or rolled paper which may be easier to scan in one continuous run rather than segment into pages. /UserUnit is independent of the pixel size and resolution of the image. /UserUnit can also indicate very small page sizes but this is not implemented here.	2017-08-20 21:19:23 +09:00
