Comment 0 for bug 1909242

I have a PDF-file that, when being cropped by "pdfcrop", is always cropped at the top by 28 pts more than expected.

For example

    pdfcrop --margins "-734 -14 -43 -42" that.pdf out1.pdf

acts as if I specified "-734 -42 -43 -42".

Trivial

   pdfcrop --margins "0 0 0 0" that.pdf out2.pdf

doesn't leave the PDF intact but removes the 28pt stripe from the top.

Interesting that cutting "0 0 0 0" again, i.e.

   pdfcrop --margins "0 0 0 0" out2.pdf out3.pdf

doesn't seem to change anything.

I'm not an expect, but I see nothing special in the original PDF file (that.pdf). The "pdfinfo" says for it:

I can provide that PDF file, but I prefer to do it privately (there's nothing secret in it, just I'm not sure if the copyright owner will be happy if I public it for everyone).

Passing this PDF through pdftk or qpdf before using pdfcrop doesn't change anything (neither in PDF appearance nor in pdfcrop behavior).
