Georg Sauthoff 2faeb2005d
Decompress stream to account for different possible encodings (closes: #51) 
Recompressing the image stream makes the comparison robust against output
preserving changes in the zlib compress output bitstream
(e.g. between different zlib implementations/versions/releases).
Without this, some img2pdf 0.3.2 tests fail on Fedora 29/aarch64.

Johannes 'josch' Schauer 9836b976d3 src/img2pdf.py: handle Pillow returning a DPI of zero (closes: #36) 7 years ago
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.
