Hi Andreas,
I guess that I couldn’t express me very well. when I said: “I was wondering if the remaining operators which identifies image graphical states would affect fonts and texts operators.” I want to mean that if that set of graphical state could affect another operators outside the q-Q stack. I understand that ‘q’ saves the graphics state and ‘Q’ restore the gs saved by q. So if a set of operators are between q and Q, it would not affect anything outside this block. The thing is that I’m not removing any q/Q operators, and it seems to affect other parts of the stream. One thing I noticed is that when I redraw the image, it creates another stream, a new one just to the new image. At this case, I have 2 streams and my content stream is actually an array of substreams as show in the figure: http://b.imagehost.org/view/0482/comparing-pdfs-in-pdfdebugger Is it possible that a gs of stream 1 affects an operator of stream 0 ? thanks, José Rodolfo Carrijo de Freitas Analista de Sistemas Softplan - Departamento de pesquisa e desenvolvimento Sistema da Qualidade Certificado ISO 9001:2008 (48) 3027 8000 Ramal 8359 http://www.softplan.com.br ---------------------------------------------------------- From: Andreas Lehmkuehler Subject: Re: copy entire stream of a page ignoring images Date: Mon, 25 Oct 2010 16:41:27 GMT Hi, Am 25.10.2010 14:28, schrieb José Rodolfo Carrijo de Freitas: > Adam, > You were right.

A graphics state isn't limited to images. All other operators are also part of a gs. > Accordingly with the spec, they wouldn’t affect.

You shouldn't remove the q/Q operator, otherwise the stack holding the graphics states may be in a mess. > I took a look with pdfdebugger on both streams(the original one, and the > edited one) comparing them. It seems to be exactly as it should, excepts for some differences in float numbers and the image operator (with its name) which I extracted, yet, they print differently. I believe There are some problems in graphics state. > > http://b.imagehost.org/view/0930/comparing-pdfs > > What kind of problem that seems to be? It looks like an unwanted scaling. Did you remove one or more of the q/Q operators? BR Andreas Lehmkühler
