[bug #55107] PDFPIC: .psbb: support extraction of MediaBox from pdf files

[Deri James]

Follow-up Comment #11, bug #55107 (project groff):


Am I correct in guessing that a bounding box/MediaBox extractor would have a
lot of shared logic for PS and PDF?  If so, one preprocessor could perform
both tasks.  I guess we could call it "grobb" or something, and assign a -B
flag to it in groff(1).  In fact, if we have a preprocessor and claim an
option letter, it's probably best if it's as general-purpose as is
reasonable.


No, unfortunately, there are significant differences. However, my option (D)
does not envisage a .pdfbb, but rather in the manner of tbl which scans the
source looking for .TS/.TE and replacing intervening lines with its own code,
it would look for .PDFPIC and insert code to achieve what PDFPIC does today.
The same is not true for .PSPIC, since we have to retain .psbb since someone
may be using it outside of its use in PSPIC.
