\placefigure[margin] but in left margin?
by Mikael P. Sundqvist 03 Jan '13

03 Jan '13

Dear list, I want to have the effect I get with \placefigure[margin] but I want it _always_ in the left margin instead of the right margin where it ends up by default. I have tried several other keys but with leftmargin, inleft the figure is not put in the top of the page, "independent of the text". Can I fix this with some setup? Small test file: \starttext \input tufte \placefigure[leftmargin][none]{With the key leftmargin}{\externalfigure[cow][width=1cm]} \input tufte \placefigure[inleft][none]{With the key inleft}{\externalfigure[cow][width=1cm]} \input tufte \placefigure[margin][none]{With the key margin}{\externalfigure[cow][width=1cm]} \input tufte % This is the way I want it, but I want it in the left margin instead \stoptext

[***SPAM***] Empty line, but not at the top of a page.
by "H. Özoguz" 03 Jan '13

Hi together and happy new year, with \crlf one can force a empty line. But this empty line should not be printed, if it is on the top/start of a new page, so a new page should not begin with an empty line. Which is the correct command for that? Regards, Huseyin

\savebuffer
by Wolfgang Schuster 03 Jan '13

Hi Hans, can you add a \savebuffer variant which works like the first version of the command where \savebuffer[<buffername>][<filename>] saved the buffer as <filename> and not as \jobname-<filename>.tmp like it currently does. Instead of a new command a key-val-version of \savebuffer would do the job as well, e.g. \savebuffer[list=<buffername>,file=<filename>,prefix=no] or something similar. Wolfgang

problems with letter module
by Wolfgang Werners-Lucchini 02 Jan '13

02 Jan '13

Hallo, I have updated context and the letter module to ConTeXt ver: 2012.12.06 22:36 MKIV fmt: 2012.12.8 int: english/english Problem: My letters do not work anymore. I have found that \setlettervalue{tax}[Steuer]{xxx} is one of the problems. I have to use \setupletter[tax=xxx] instead. I have to lock for then tax renaming. Now the letter is compiling, but it is completly broken. In the log I have found a lot of lines setup > error in line 20, namespace "553", instance "letter", key "frame" setup > error in line 58, namespace "539", instance "letter", key "invoice" setup > error in line 58, namespace "539", instance "letter", key "date" setup > error in line 58, namespace "539", instance "letter", key "phone" setup > error in line 58, namespace "539", instance "letter", key "tax" I have the impression, that there has a lot changed. How can I fix this temporary? (I have to write my letter NOW!) Wolfgang

Dear Wolfgang, Thank you for the explanation, and your sample works nicely. I enclosed \processMPbuffer using \startframe and \stopframe as following. Then I got a 'undefined control sequence' error. If I use '\framed[]' instead of '\startframe … \stopframe', then it gave all 7 circles of different radius in two pages without error. If I add "\startanimation … \stopanimation", the only change is the appearance of menu at the bottom of the last circle.(no animation) What is wrong in the code? Best regards, Dalyoung Happy New Year to all listers!!! %%%%%%%%%%%% \startbuffer[circles] path p; numeric n, u; u := 1cm; n:=\recurselevel*u; p := fullcircle scaled n; draw p; \stopbuffer \usemodule[animation] \setupinteraction[state=start] \starttext %\startanimation[menu=yes] \dorecurse{7}{ \startframe % \framed[]%{\processMPbuffer[circles]}} \processMPbuffer[circles] \stopframe } %\stopanimation \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%% !

Dear Troy, The animations are impressive and thank you for sharing the code. In the creation of many pdf for animation, it changes the recurselevel only. I wonder if there is a way to make such kind of animation in ConTeXt using Wolfgang's animation module. Then we can include the animation in PDF output directly. Here is my trial. I modified it as following and got an animation. But it is only good for a few step animation. %%%%%%%%% \startbuffer[base] N:=64;%\N; u:=136; pair f; c:=2/(1+sqrt(5));%\c; if c<1: f:=(1+-+c,0); v:=u/2; else: f:=(0,1+-+(1/c)); v:=u/c/2; fi; % Focus f is defined path p,q; pair z; picture base; numeric L; p:=fullcircle yscaled c; % This is the ellipse L:=length p; draw p scaled (2*v) withpen pencircle scaled (v/260) dashed evenly; % Draw the ellipse dashed (will be traced later) base:= currentpicture; q:=bbox currentpicture enlarged (v/64); % Enlarge the bounding box slightly q:=(llcorner q+(-v/128,-v/128))--(lrcorner q+(v/128,-v/128))--(urcorner q+(v/128,v/128))--(urcorner q+(-v/128,v/128))--cycle; fill fullcircle scaled (v/32) shifted (f*v) withcolor red; % Focus fill fullcircle scaled (v/32) shifted (-f*v) withcolor red; % Focus base:=currentpicture; % Save this picture to draw in every frame setbounds currentpicture to q; % Set the bounding box as described before \stopbuffer \startbuffer[fig1] % \startMPpage n:=1;%\recurselevel%1; draw base; % Draw the common picture saved above draw subpath (0,(n-1)/(N-1)*L) of p scaled (2*v) withpen pencircle scaled (v/130) withcolor blue; % Trace the ellipse in blue z:=point ((n-1)/(N-1)*L) of p scaled v; % The point on the ellipse where we are thusfar fill fullcircle scaled (v/32) shifted (2*z) withcolor blue; % Draw the point draw (-f*v)--(2*z)--(f*v) withpen pencircle scaled (v/260); % Draw the string used to trace the ellipse setbounds currentpicture to q; % Set the bounding box so that it is the same for each frame % \stopMPpage \stopbuffer \startbuffer[fig2] % \startMPpage n:=2; draw base; % Draw the common picture saved above draw subpath (0,(n-1)/(N-1)*L) of p scaled (2*v) withpen pencircle scaled (v/130) withcolor blue; % Trace the ellipse in blue z:=point ((n-1)/(N-1)*L) of p scaled v; % The point on the ellipse where we are thusfar fill fullcircle scaled (v/32) shifted (2*z) withcolor blue; % Draw the point draw (-f*v)--(2*z)--(f*v) withpen pencircle scaled (v/260); % Draw the string used to trace the ellipse setbounds currentpicture to q; % Set the bounding box so that it is the same for each frame % \stopMPpage \stopbuffer \startbuffer[fig3] % \startMPpage n:=3; draw base; % Draw the common picture saved above draw subpath (0,(n-1)/(N-1)*L) of p scaled (2*v) withpen pencircle scaled (v/130) withcolor blue; % Trace the ellipse in blue z:=point ((n-1)/(N-1)*L) of p scaled v; % The point on the ellipse where we are thusfar fill fullcircle scaled (v/32) shifted (2*z) withcolor blue; % Draw the point draw (-f*v)--(2*z)--(f*v) withpen pencircle scaled (v/260); % Draw the string used to trace the ellipse setbounds currentpicture to q; % Set the bounding box so that it is the same for each frame % \stopMPpage \stopbuffer \setupinteraction[state=start] \usemodule[animation] \starttext \startanimation[menu=yes] {\processMPbuffer[base, fig1]} {\processMPbuffer[base, fig2]} {\processMPbuffer[base, fig3]} \stopanimation \stoptext %%%%%%%%%%%%% I also tried to simplify the code as following, but it just draw 10 figures not an animation.

MetaPost Animations
by Troy Henderson 29 Dec '12

I've created several animations using MetaPost/ConTeXt, and I have also created a webpage with these animations. The URL to the page is http://www.tlhiv.org/animations/ Feedback is appreciated, and if there is a particular animation that you would like to see included, let me know and I will attempt to code them up in MetaPost, provide the source code, and include them on the webpage.
