Package: ppdfilt
Version: 2:0.10-4
Severity: normal
ppdfilt -Z numer-up:4 creates empty pages on output from
gs -sDEVICE=pswrite. The reason seems to be that gs puts
setpagedevice commands at the beginning of each page, which
is not redefined by ppdfilt, so discards the information that
this page should only occupy a part of the page.
(adding
/setpagedevice {pop}bind 1 index where{dup wcheck{3 1 roll put} {pop
def}ifelse}{def}ifelse
which psnup adds there helps here,
but as psnup is redinining some more commands (initclip, initgraphics, ...)
I guess there are other postscript documents even without setpagedevice
which will fail to be processed correctly with number-up).
Hochachtungsvoll,
Bernhard R. Link
