math detail

Hi, in this example $V^0$ the 0 is too high (conflict with the line above). On the other hand, without math V\high{0} there is *no* conflict with the line above. ["conflict" means the given interlinespace gets bigger in this line] Thus, two questions: 1) Why does it has to be like this? 2) As it is not possible to choose a bigger interlinespace, is it possible to adjust the high/depth of the superset math element "^0" ?

processing a file of figures
by Alan Bowen 12 Dec '08

12 Dec '08

I am working on a book in which the figures are to appear in a separate section at the end. Is there a good way to do this? Right now I have a file which is a sequence of commands, e.g., \useexternalfigure[Graphic][... \placefigure[... \useexternalfigure[Graphic][... \placefigure[... where each figure is assigned its own page. The problem is that, while I can process this file by itself, when it is part of product file (this file and others are components), strange things occur. (Basically it seems that ConTeXt has problems with the running heads used throughout the book, and with finishing the file.) But before going into this, I was wondering if perchance there is a better way to get ConText to process a file that is no more than sequence of figures. I am using the latest ConTeXt and MkII. Alan

help with a latex -> context conversion

Hello: I am intending to write my masters thesis using context. My university publishes a style guide in addition to a latex cls file. I am trying to reproduce the titlepage.

Copy & Paste chinese in PDF files
by Yu Yi 12 Dec '08

12 Dec '08

hi, I'm thinking now whether change from latex to context. As I know, both latex and context support the chinese language, but like in Latex, there is a problem with generated PDF, that is, the chinese words can not be copied and pasted correctly as the english words, how about this function in context? Anyway, this does not work in the provided manuals and examples! appreciate for any tips! Yu Yi

Hmm... we tried this, but it doesn't seem to make any obvious difference. Is this supposed to give a speed improvement? or get around the maxnumMPgraphics limit? Thanks again for your help. Lars

Thanks again for that! Unfortunately, when I generalize it, it takes us back to producing triple borders between adjacent cells. I think this is inevitable when overlaying a double frame (for certain sides) on top of a single frame for all sides, because a double side overlaid on a single side cannot be centered (or else the single line shows through separately from the double line). So my fix... which I'm posting here in hopes that someone may refine it, and for the benefit of others who may attempt similar things... is to center the double frames between the cells and avoid overlaying a double frame side over a single frame side. We center borders between the cells by using "enlarged" values -0.2 +/- k, i.e. center around -0.2. I'm not sure why -0.2 works better than zero, but it does... Doing this makes coincident border lines from adjacent cells look like ordinary single lines instead of being extra thick. We settled on k = 0.6 to get the desired distance between our double lines. Incidentally, I wish I knew how to put -0.2, 0.2-k, and -0.2+k into variables or something so that they could all be changed in one place, instead of hard-coded in many places. Maybe somebody can help me there. A cost of this single-overlay-per-cell approach is that we have to specify individually the 16 possible overlays (combinations of single and double edges) for any possible cell. But that's not too bad, as we only have to define them once. (In practice, we also had to define a couple of special cases where we needed some cells with open edges for a "faked rowspan". We haven't completely got those working yet.) An unexpected and potentially large benefit of this approach is that for each cell, we only generate one MPgraphic (apparently because we only use one overlay per cell), which should make the TeX run much faster, and avoid running over the maxnumMPgraphics limit. With the multiple-overlay-per-cell approach, we ended up using about 13,000 MPgraphics for our document, far beyond the default limit of 4000, and taking 15 minutes to run compared to 37 seconds for a similar document without the tables. Here is our working system... hope it's helpful to somebody: %%%% define MPgraphics for double-ruled tables % Lars Huttar, 2008-12-09 % Thanks to Wolfgang Schuster on NTG-list % Each MPgraph (and overlay) is named lrtb, with capitalized letters indicating which sides are double-ruled. % Adjacent cells must not define their common side differently, e.g. one cell define it single and one side % define it double;
