[NTG-context] Presentations with ConTeXt
Hello everyone. I would like to know if there exists in ConTeXt some mechanism similar to LaTeX Beamer to make presentations showing each element step by step. In Beamer the \pause command is used and it is quite simple. Can I have something similar in ConTeXt, simple and easy to use? Thank you Manuel González ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Adding a layer with a red circle drawn in Metapost, then positioning

What kind of picture do you have? If you have .jpg/.png/..., you can
get (x,y) position of the pixel where the center of circle should be.
One possibility is to create a new metapost figure and draw the circle
on it using the measured coordinates:
(This circles the blue tulip on
http://contextgarden.net/images/6/65/Kochloewe_c.jpg.)
\setupcolors[state=start]
\starttext
\startuseMPgraphic{CircleBlueTulip}
% center point
pair size, c;
% figure will be 10 cm wide
scale := 10cm/400;
% center of the blue tulip is on (219,333), image is 400*460
size := (400,460) scaled scale;
c := (222,460-330) scaled scale;
% diameter of the circle should be 50 pixels
d := 50scale;
pickup pencircle scaled 2pt;
externalfigure Kochloewe_c.jpg xyscaled size;
draw fullcircle scaled d shifted c withcolor red;
\stopuseMPgraphic
\useMPgraphic{CircleBlueTulip}
\stoptext
I believe there exists a more straightforward way if you make
uniqueMPgraphic and specify coordinate fractions of the circle to be
drawn, but if you say:
\framed[background=SomeGraphicWithACircle]{\externalfigure[Kochloewe_c][width=10cm]},
the circle (if any) is drawn behind the figure and cannot be used as
such. Unless you specify the figure in a new layer and draw both
layers in the proper order.
In this case it would be fine to have a \framed[...foreground=...] command :)
And lastly: I have never seen transitions working on OS X (both
Apple's Preview and Adobe Reader 7.0). Can anybody confirm that they
got this working on other systems?
They work in Windows XP (I'n not sure if they're also working using
ConTeXt commands). But they are so ugly that you don't want to use
them.

Use
\framed
[background={foreground,BgFront}]
{\externalfigure[Kochloewe_c][width=10cm]}}
Define your picture as BgFront. 'foreground' is fixed word that
identifies layer 0 (text). So you can stack bacground as follow:
background={...,MyLayer-2,MyLayer-1,foreground,MyLayer1,MyLayer2,...}

Uau! Thanks a lot for a very nice hint. So you can make something like that:
\setupcolors[state=start]
\starttext
\setupMPvariables[CircleSomething][dimension={(100,100)},center={(50,50)},r=10]
\startuseMPgraphic{CircleSomething}
pair dimension, center;
% TODO: this also has to be passed as parameter!!!
% now it stands for: width=10cm
scale := 10cm/(xpart \MPvar{dimension});
picture bboxpicture;
dimension := \MPvar{dimension} scaled scale;
center := \MPvar{center} scaled scale;
r := \MPvar{r}*scale;
pickup pencircle scaled 2pt;
% proper bounding box
fill unitsquare xyscaled dimension;
bboxpicture := currentpicture;
currentpicture := nullpicture;
draw fullcircle scaled (2*r) shifted center withcolor red;
setbounds currentpicture to boundingbox bboxpicture;
\stopuseMPgraphic
\defineoverlay[CircleBlueTulip][\uniqueMPgraphic{CircleSomething}{dimension={(400,460)},center={(222,460-330)},r=25}]
\defineoverlay[CircleRedTulip][\useMPgraphic{CircleSomething}{dimension={(400,460)},center={(148,460-330)},r=25}]
\framed[background={foreground,CircleBlueTulip},offset=0pt,strut=no]{\externalfigure[Kochloewe_c][width=10cm]}

[NTG-context] presentations in ConTeXt
I've decided to bite the bullet and do my presentations in ConTeXt this term. So far, I'm quite satisfied. I've done only very basic stuff so far (if you're interested, you can have a look at http:// www.uni-bonn.de/www/Philologie/Personal/Schmitz/Dateien.html ), but I like the result. The background is just a pdf-image that I created with metapost and reused as a page background (I found this was faster and easier than recalculating it every time...) Things I would like to know: I like the idea of having the small bar showing at which place in the presentations we are (such as in pre-colorful). I'd like it very minimal, though: maybe just grey squares, with the current position being white or yellow. I have a hunch that this could be achieved with \setupinteractionbar, but this command is a bit underdocumented. Hints, anybody? I am still at a loss how to achieve one thing in ConTeXt that was pretty easy in Keynote or (shudder) Powerpoint: When I wanted to highlight something on a map or a picture, I would just draw a red circle around it. What would be the proper way to do this in ConTeXt? Adding a layer with a red circle drawn in Metapost, then positioning it by trial and error? Or can anyone point to a better solution? And lastly: I have never seen transitions working on OS X (both Apple's Preview and Adobe Reader 7.0). Can anybody confirm that they got this working on other systems? Sorry for the long post. I'm hoping for some enlightenment. Best Thomas ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
