Bug with overprinting in Mark II/IV?
by Oliver Heins 13 Dec '09

13 Dec '09

Hello, with color black overprinting is not working. You can easily spot this when you use the »Ausgabevorschau« (sorry, my acrobat is in german locale, must be something with »preview« in english; located in the »tools« menu) in acrobat and remove magenta and black from the preview. Whilst under the region with the magenta colored text the picture gets shown, in the region with the black colored text the text is cut out of the picture, leaving white. I think this is a bug, as overprinting makes most sense with black. It happens both in Mark II and IV -- you have to manually copy the hacker.jpg to your working directory (under linux e.g. with cp $(kpsewhich hacker.jpg) /path/to/your/working/directory) and change the path to make the minimal example work under mark iv.

Overfull \hbox in Every Footnote

As you can see in the results of processing the ConTeXt code below, the footnote gives an "Overfull \hbox" warning.

How to use vim's syntax folding
by Hubertus 12 Dec '09

12 Dec '09

Hello, I was wondering it there's an easy way how I can use vim's syntax-folding. I've checked the context syntax files, but there doesn't seem to be anything there. I also had a brief look at the folding.vim from the LatextSuite, but alas could not adapt it easily. Is there anyone using this feature? thx Hubertus

Can someone please explain why the margin command does not work in this example? What can I do to obtain the margin. Thanks. \setuppapersize[letter][letter] \starttext \input tufte \startitemize \item This is the first item of outer list. \startitemize[a][stopper=)] \item Context is great.

overprinting backgrounds
by Oliver Heins 11 Dec '09

11 Dec '09

I have another question. The print shop wants the background image to be overprinted. Is it sufficiant to set »overprint=yes« once in \setupcolors or does one need to explicitely tell the region with \startoverprint ... \stopoverprint? A minimal example: % \startminimalexample \setupcolors[state=start,cmyk=yes,rgb=no,overprint=yes] \definelayer [mybg] [x=0mm, y=0mm, width=\paperwidth, height=\paperheight, repeat=yes] \setlayer [mybg] [hoffset=5cm, voffset=7cm] {\externalfigure[sample/hacker.jpg][max]} \setupbackgrounds[page][background=mybg] \starttext Is this sufficiant for overprinting? \dorecurse{4}{\input tufte\par} \page \startoverprint Or does one need to explicitely tell context the region? \dorecurse{4}{\input tufte\par} \stopoverprint \stoptext %\stopminimalexample Thanks again, olli -- Oliver Heins heins(a)sopos.org http://oliverheins.net/ http://blog.overheins.net/ F27A BA8C 1CFB B905 65A8 http://scriptorium-adp.de/ 2544 0F07 B675 9A00 D827 1024D/9A00D827 2004-09-24 -- gpg --recv-keys 0x9A00D827 Please avoid sending me Word or PowerPoint attachments: http://www.gnu.org/philosophy/no-word-attachments.html

Other strange effects with overprinting (Mark II only)

overprinting and underbar (mkiv)
by Peter Rolf 11 Dec '09

11 Dec '09

Hi, if \underbar is used inside of an overprinted test, the underbar line does not share the OVP attribute. Mkii works as expected, meaning the stroke is part of the text and should be handled equally. A minimal example is attached. MTXrun | current version: 2009.11.26 16:28 This is LuaTeX, Version beta-0.46.0-2009112616 Best wishes, Peter \setupcolors[state=start] \setuppagenumber[state=stop] \starttext \setupunderbar[bottomoffset=2pt,rulethickness=2pt] \startoverprint \switchtobodyfont[60pt]\underbar{O}K \stopoverprint \stoptext

Multi-line Footer?
by Scot Johnson 09 Dec '09

09 Dec '09

Hi All, I'm new to ConTeXt and am working on a document that needs some text put on each page of output. I had thought I could use the following but it doesn't work: \setupfootertexts [SPECIFICALLY NEGOTIATED LICENSE RIGHTS\\Use or disclosure of this data is subject to the restriction on the first page of this document.] When I do this, the output is all on one line and clipped off at the beginning and end. Is there a way to put this text in the footer without clipping it off? Thanks in advance for any help offered! -- Scot
