Hallo pdftexdevelopers, there is a bug in \pdfxform. See the next example: ----------------------- \pdfcompresslevel=0 \footline={\hfill}% \setbox0\vbox{\hsize8.75cm\noindent Ahoj} \pdfxform attr{/Matrix [1.2 0.25 0.3 1 0 0]} 0 \pdfrefxform\pdflastxform \end ------------------------- The result XObject looks like: ------------------------ 1 0 obj << /Type /XObject /Subtype /Form /Matrix [1.2 0.25 0.3 1 0 0] /BBox [0 0 248.031 8.856] /FormType 1 /Matrix [1 0 0 1 0 0] /Resources 6 0 R /Length 69
stream 1 0 0 1 0 -833.034 cm BT /F1 9.963 Tf 0 834.971 Td[(Aho)-55(j)]TJ ET endstream endobj
See the double /Matrix entry. That results in ignoring transformation by Acrobat (R) v.6 and 7. (v.4 and v.5 is OK). I believe that it is (exceptionally) bug in pdftex not in Acrobat ;) vit

pdftex is (and will) not parsing the content of attr, so the duplicate entry si a feature; conforming the specs acrobat should look at the first entry and if they broke that ...

In general, the precedence of doubled entries seems to be interpreter dependent, not only for XObjects. I've added such a comment to pdfTeX man, but it seems it should be bolded. BR, -- Pawe/l Jackowski P.Jackowski@gust.org.pl

Looking for the string "/Matrix" without full parsing could be done.

Have I missed something? When did they change this?
PDF spec. 1.6 says in 3.2.6 "Dictionary Objects":
| Note: No two entries in the same dictionary should have the same key. If a
| key does appear more than once, its value is undefined.
Yours sincerely

in previous versions the first one was taken; that way one could overload the info entries; even if it was 'behaviour' and not 'specification' i more and more tend to think that adobe does not care much about downward compatibility at all 'the first value is taken' would have been ok Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

The behaviour for duplicate dictionary entries is undefined; you may get the first or the last. Best regards Martin -- http://www.tm.oneiros.de
