I'm a latex user, but I am fascinated by context. I've a project and I'd like to know if it's possible to do it in context. The idea is the following: I have to draw a directed graph representing relations between musical elements. My graph is made of nodes and links. Links are represented as arrows as usual, but they should include a label with text displayed near to each of them. Nodes should be blocks of musical notation. Now, I'm using lilypond to generate musical fragments (www.lilypond.org). Lilypond outputs ps, pdf and png also. For my project actually I am using the pgf package under latex. In this way I can create graphs: I can draw lines with arrows, I can give each vertex an xy pair of coordinates, and I can associate each vertex an external figure. But I'n not satisfied with the output, and I like very much context capabilties: more, metafun is amazing. Taking a look at the metafun doc, it seems to me that the drawing the edges should be a very simple task. But: is it possible to import an external figure inside metapost giving it a precise place in terms of xy coordinates? Thanks a lot -a- ^ permalink raw reply [flat|nested] 8+ messages in thread

Sure: externalfigure "filename.pdf" xyscaled (theWidth, theHeight) shifted (theLowerLeftX, theLowerLeftY); (However, I don't know if there's a way to include a picture without the need to provide width and height explicitly.)

Of course they do. Metapost is clever enough to calculate the proper bounding box. If you "draw origin" or "draw origin shifted anypointyoucanthinkof" and if that is the only thing you draw, than both figures will be identical. If you would like the figure to be different, you can set the bounding box explicitely with: setbounds currentpicture to unitsquare xyscaled ... shifted ...; If you want your graphic to appear somewhere else on the page than you have to handle that with plain TeX/ConTeXt commands to achieve the desired placing ... or using layers in MetaFun. > So, how do I know all the options I can use? Simply I can't? The command externalfigure in MetaFun has no additional options/parameters. The best place to learn metafont/post/fun is: - take The METAPOSTBook in a library (not necessary) - metapost manual: http://www.tug.org/tutorials/mp/mpman.pdf - MetaFun manual: http://www.pragma-ade.com/general/manuals/metafun-s.pdf - sources: go to http://source.contextgarden.net/ and search for externalfigure for example I usually use the metapost and metafun manual and simply the search function in Adobe Acrobat fo find what I'm looking for. Reading the whole metafun manual is no bad idea anyway. If you're looking for ConTeXt documentation: well, yes, than you start reading one manual after another, keep looking into the source code and search through the mailing list archive & contribute to Wiki. I'm affraid there's no other way for the moment. Mojca ^ permalink raw reply [flat|nested] 8+ messages in thread
