Bug description:
I have just noticed a problem caused by the change on 3 Oct 2011, which
prevents pdfopt from linearizing pdflatex-generated files at least under
Ubuntu
12.04:
[IMPACT]
pdfopt does not work on any file generated by pdflatex.
[TESTCASE]
Cited from the original reporter of this bug:
----------
How to reproduce the problem:
ghostscript/9.05 is used by Ubuntu 12.04. Linearizing a pdflatex-generated
file
does not work here. For test, simply /usr/share/doc/texlive-
doc/latex/curve/curve.pdf can be used with pdfopt:
dreibh@lupo:/tmp$ pdfopt /usr/share/doc/texlive-doc/latex/curve/curve.pdf
x.pdf
**** Considering object with an invalid number 264 as null.
**** Considering object with an invalid number 265 as null.
**** Considering object with an invalid number 264 as null.
**** Considering object with an invalid number 265 as null.
dreibh@lupo:/tmp$ pdfinfo x.pdf
Producer: ESP Ghostscript 815.03
CreationDate: Mon Feb 25 18:03:04 2008
ModDate: Mon Feb 25 18:03:04 2008
Tagged: no
Pages: 26
Encrypted: no
Page size: 595 x 842 pts (A4)
File size: 184754 bytes
Optimized: no ########### <<-- not linearized
PDF version: 1.3
I have therefore reverted the change in pdf_base.ps:
- 1 index 0 lt {
- ( **** Considering object with a negative number as null.\n)
pdfformaterror
+ 1 index dup 0 lt exch NumObjects ge or {
+ ( **** Considering object with an invalid number )
+ 2 index 20 string cvs concatstrings
+ ( as null.\n) concatstrings pdfformaterror
Now, pdfopt works as before:
dreibh@lupo:/tmp$ pdfopt /usr/share/doc/texlive-pictures-
doc/latex/curve/curve.pdf y.pdf
dreibh@lupo:~/tmp$ pdfinfo y.pdf
Producer: ESP Ghostscript 815.03

----------
After installing the proposed package this problem should disappear,
getting
...
Optimized: yes
...
without needing to edit pdf_base.ps.
[Regression Potential]
Very low, as only a simple consistency check got removed by the patch,
on the rendering nothing is changed.
