inclusion from image database broken (mkii+mkiv)

inclusion from image database broken (mkii+mkiv)

[Peter Rolf]

hi,

when i try to include an image from one of my databases i get the 
following error messages:

mkii:

!pdfTeX error: pdftex.exe (file ./lib/test-db.pdf): xpdf: reading PDF 
image failed (0)
  ==> Fatal error occurred, no output PDF file produced!


mkiv:

!luaTeX error: xpdf: reading PDF image failed
  ==> Fatal error occurred, no output PDF file produced!


i looked into the mkiv sources, but didn't succeed. the lua part (db 
only) is clear to me, but i couldn't find the point in tex, where 
\externalfigure is mapped to this somehow. either i have missed 
something or there is some code missing. mh, probably the first one :)

regards, peter


ps: any news about the \string{\{} problem in mkiv?

i dunno; if there's indeed a file in ./lib/test-db.pdf then it's an xpdf 
problem so maybe you need to preflight the file and see what's wrong 
with it

this is :

\string { -> letter {
\{ -> depends on definition but probably no bgroup
} -> egroup

so whatever happens, you'll probably end up with closing a group which 
in turn will result in an error someplace

Use \convertargument\{\to\ascii and \ascii.

ok, checked; the database pdf is *valid*.

i even created a new database pdf that uses the default lm roman font... 
brrrr, looks ugly and incredibly blows up the size (patched that 'back' 
to adobe helvetica t1 from reader).
still same error for both marks. i donno either ;)

i can make a minimal example(<100kb), so you can look into it when you 
have time. there are still problems with clipping in mkiv, but my first 
try to create a breaking minimal failed. so far db problems and clipping 
in mkiv are the only issues left (rest looks pretty good!).

regards, peter

first of all: *thanks to luigi* for testing and for using the 'right' 
binary versions (which was the key) :)

now the news:
- pdftex 1.40.7 works fine with my test file. the only thing is, that it 
complains about the wrong pdf version of the included db file.
..
pdfTeX warning: pdftex (file ./lib/test-db.pdf): PDF inclusion: found 
PDF version <1.6>, but at most version <1.5> allowed

- luatex 0.25.3 doesn't break, but includes always the first image in 
the database. if i remember it right this was a filter problem.


- pdftex 1.50alpha and
   luatex trunk (17.05.2008) fail with the described error


the latest official released versions of luatex and pdftex generate a 
working pdf. both developement versions fail. i guess there is a bug in 
the pdf inclusion routines, as this is all that is done in my test file.
if someone can tell me how i can pass the pdfminorversion as runtime 
parameter, i can create a database in pdf1.4 and test it again with a 
more 'compatible' pdf version. anyhow, i quit for today...


best wishes, peter
