The example demonstrated that it *IS* drawn white box in the background of every metaobj object. Exactly as you mentioned. But I had a second look into mpobj.mp and probably find out the white box tiger. Comment line 750: unfill BpathObj(n); I am sure this hack will cause some unpleasant side-effects (e.g. with shaded boxes) but in some limited situations... Vit Zyka

Re: [NTG-context] Best source of ConTeXt documentation?

I'd like to see the sources of all the PDF files available at pragma-ade. Its much easier to look at examples and learn from it than to ask for complete documentation. Salman

Best source of ConTeXt documentation?
by Brooks Moses 01 Aug '04

01 Aug '04

In my efforts to learn ConTeXt, I'm continually getting stuck by a lack of having complete documentation. For example, consider the \definestartstop command, which I was recently looking at. * In the cont-enp.pdf manual, it's not mentioned. * In the mp-cp-en.pdf manual, there's an example of it, but it's not really very clear what the difference is between what the "commands=" and "before=" options do. In addition, there's no indication whether these are all the possible options or not, or whether there's any way to define a start/stop pair that takes an argument. * In the source, I can find the definitions, but for that particular one there seems to be very little commentary, and I also suspect I'd need to be rather familiar with the ConTeXt core before I could understand it -- I certainly can't see where the "before=" goes in, for instance. And that's about all I know about, other than doing a Google search on the mailing-list archives, which rarely addresses the general stuff. Is this all due to an actual lack of documentation for ConTeXt itself, or is there something large and important that I'm missing? Thanks, - Brooks

Define new flow chart cell shape
by Pedro Mendonça 01 Aug '04

Hi Hans! I'm using the flow chart module and I want to know how to create a new cell shape using MetaPost and assign that new shape to a shape number. Could you give me an example? Thanks.

Metapost: minus sign as "unknown"
by Christopher Creutzig 01 Aug '04

01 Aug '04

Dear list, please find attached a small ConTeXt file using metapost and mp-format.mp. When compiled directly (with \write18 enabled), the minus sign of the first MPgraphic is rendered (by metapost) as "unknown". The very same code in the second example works. When compiling with texexec --automp, the problem does not exist. Versions: This is pdfeTeX, Version 3.14159-1.10b-2.1 (Web2C 7.4.5) ConTeXt ver: 2004.6.26 fmt: 2004.7.17 int: english mes: english This is MetaPost, Version 0.641 (Web2C 7.4.5) metafun 2004-7-17 22:18 TeXExec 3.3 - ConTeXt / PRAGMA ADE 1997-2003 TeXUtil 7.5 - ConTeXt / PRAGMA ADE 1992-2003 regards, Christopher Creutzig
