mkiv fails to load pdf image

[zs]

[-- Attachment #1: Type: text/plain, Size: 592 bytes --]

Hi all,

I found that using latest I cannot get readable pdf file from folowing minimal code.

This is LuaTeX, Version beta-0.43.0-2009081914
ConTeXt  ver: 2009.10.02 13:14 MKIV  fmt: 2009.10.5  int: english/english
..... "context minimal" gives me corrupted pdf.
..... "texexec -pdf minimal" works OK.


This is LuaTeX, Version beta-0.40.6-2009062513
ConTeXt  ver: 2009.06.14 21:01 MKIV  fmt: 2009.7.15  int: english/english
..... everything works OK.


\starttext
\placefigure[here,force][]{none}{\externalfigure[example.pdf][width=10cm]}
\stoptext

The "example.pdf" is attached.

Works OK here.

This is LuaTeX, Version beta-0.43.0-2009081911

You don't need the 'pdf' parameter for texexec because PDF is the  
default output format.

Use 'none' as \placefigure argument in MkIV (\placefigure 
[here,force,none]{}{...}).

Here ConTeXt  ver: 2009.09.25 12:15 MKIV  fmt: 2009.9.25, as well as
ConTeXt  ver: 2009.09.28 09:02 MKIV  fmt: 2009.10.5 with luatex 0.43
both result in an invalid page catalog with compression on (default):

   xpdf ex.pdf
   Error: Catalog object is wrong type (null)
   Error: Couldn't read page catalog

and with just a broken xref table with object compression off
(\nopdfcompression or \pdfobjcompresslevel=0):

   xpdf ex.pdf
   Error: PDF file is damaged - attempting to reconstruct xref table...

Somehow this is related to the example.pdf, because using cow.pdf works
just fine.

Best wishes,
Taco

Also, after

   pdf2ps && ps2pdf example.pdf

it works correctly also.

...yes it it related to the example.pdf or better to any pdf produced by cairo library (1.8.6 in my case).
Using other pdf producers (pdflib, gs) file inclusion works fine.

Do you suppose it is cairo's fault? If yes, why did it work before?

Further investigation:
example.pdf does not seem to be corrupted.
Applying pdfopt to that does not help.
Conversion pdf->ps->pdf through gs makes it usable for inclusion by recent minimals.

example.pdf has a /Group. And it works here in pdfTeX 1.50 & LaTeX.
Can LuaTeX handle pdf inclusion with transparency groups?

This could very well be the problem.

It was formerly able to handle it seamlessly for very long time, only recent version cannot.

That means it is probably a regression caused by the backend rewrite.
I will create an item for this in the bug tracker.
