An important question: overpainted for your personal needs or in order to remove some information from PDF that others are not supposed to see?

Mojca

I need to upgrade some drawings, or more precisely, to upgrade their title block as some its fields need to be changed (e.g. date 9/2010 to 1/2011, the "level" of the documentation and so on). Finally, the PDFs are to be printed to a physical printer (=> physical pieces of paper) and also to be provided to the third party like digital documents. The result should not have layers switchable to on/off, but I believe this can be handled by printing the final (even layered) PDF to another PDF by a virtual printer (e.g. pdfCreator). Layering was only an idea, which - as I believed - should lead to the goal; although that would probably mean to print the (layered) PDFs manually to the virtual PDF printer. Or is there another (non-layering or layer-merging) way? Regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

You can also crop the pdf (\clip[mp=shape that you want to clip]{\externalfigure[...]}) and place that on paper using layers. That way, even if layers are toggled on a pdfviewer, the reader will see blank text (as opposed to old text).

Hello, thanks to all for the answers, Peter's solution is closest to that I need. My code now is: --- \setuppapersize[A1,landscape] \setuplayout[page] \setuppositioning [state=overlay, yoffset=-12pt % Why? ] \starttext \startpositioning \position(0,0){\rotate[rotation=90]{\externalfigure[TvNK]}} \position(630mm,297mm){\framed[frame=off,offset=overlay,background=color,backgroundcolor=white] {\externalfigure[_R]}} \stoppositioning \stoptext --- I'd still have two questions: - Is it possible to determine the size of the PDF being inserted (in my case the "TvNK", which is A1)? I'd need to know this because depending on this, I'd need to \setuppapersize[<size-of-PDF-to-be-inserted>,landscape]. - Is it possible to "move" the origin for \positioning to the right bottom corner? It's not "fatal" to know it, as having the PDF size known, I can evaluate 630mm = width.of.A1 - width.of.A4 and 297 = height.of.A1 - height.of.A4; I'm just curious.

Not necessary, context can produce such files for you.

Example, using positioning macros, that shows also a problem with vertical offset:

\layeredtext is described in the details manuals.

Which exactly do you mean? I searched for some information about "\layeredtext" and "\startTEXpage[background=". I tried wiki, contextref.pdf and google, also several from http://www.pragma-ade.com/show-man-1.htm, but I'm not much smarter so far. Best regards, Lukas

You don’t need “backround={…}”, it’s a leftover from a earlier attempt to find a nice solution to your problem. \startTEXpage … \stopTEXpage produce a separate page for it’s content where the page is a large as the content itself, try: \starttext \input knuth\par \startTEXpage[width=10cm] \input knuth\par \stopTEXpage \input knuth\par \stoptext
