[poppler] Printing of certain PDF files does not work with "fit-to-page" because of wrong BoundingBox values in the PostScript

[Martin Pahl]

Attached you find an example:

example.pdf: a box generated with xfig 321mm x 106mm

example.ps generated with pdftops -paper A4 example.pdf
example.ps:%%PageBoundingBox: 0 0 302 912

example-patched.ps generated with pdftops -paper A4 example.pdf, but with the 
patched version.
example-patched.ps:%%PageBoundingBox: 158 0 437 842

You can view the postscript files with gv and select BBox. It's obvious that 
the unpatched PageBoundingBox is totally wrong, because source coordinates are 
used. The PageBoundingBox is bigger then the A4 paper format. It's just the 
size of the original box (302 /72 dpi * 25,4mm = 106,5mm; 912/72 dpi * 25,4mm 
= 321,73mm). But it must be the box scaled down to A4 and shifted to the 
center.

Hope this example helps.

Regards,

Martin Pahl
