[NTG-context] Re: Strange behavior with anglestriped()
Hi, Fabrice, you have a problem with the definition of the path b: this path include q and b. To see this, replace your lines with : draw q anglestriped (1,45,2) withcolor cyan; draw b anglestriped (1,45,2) withcolor red; And you will see that the path b is drawn twice : once in red, once in cyan. So if you change your instructions to : draw q anglestriped (1,45,2) withcolor cyan; draw r anglestriped (1,45,2) withcolor cyan; This will correct the problem, because each path is now drawn only once.

Of course, some have seen the amazing things we can do with ConTeXt, and are using it a bit, but installation remains a challenge for most of them. Being able to work and share an overleaf project is a way to work in a collaborative way in ConTeXt (and Metafun of course !). > > Aditya Tanks agin for the tip !

Hi, Initially, there was a bug with maro numberstriped() and Hans suggested another sensible approach to me, but you don't get the same shape of the hatches depending on the dimensions of the squares. Your solution works perfectly but I'm trying to understand the action of the parameters: the first ? the second represents the angle in degrees that the segments make the third represents the gap between two segments Thanks Fabrice Le sam. 1 oct. 2022 à 21:46, Mikael Sundqvist via ntg-context < ntg-context@ntg.nl> a écrit : > Hi, > > Is this what you are looking for? > > On Sat, Oct 1, 2022 at 7:43 PM Fabrice Couvreur via ntg-context > wrote: > > > > Hi Hans, > > When the rectangles are not identical, how to have the same type of > hatching in both ? > > Thanks. > > Fabrice > > > > > > \starttext > > \startlinecorrection[blank] > > \startmidaligned > > \switchtobodyfont[9pt] > > \startMPcode > > path p, q, r, b ; > > p := unitsquare xyscaled (4cm,4cm) ; > > z[0] = (2cm,0cm) ; > > z[1] = (2cm,4cm) ; > > z[2] = (0cm,2cm) ; > > q := llcorner p--z[0]--z[1]--z[2]--cycle ; > > r := unitsquare xyscaled (1cm,1cm) shifted(0,3cm) ; > > b := unitsquare xyscaled (3cm,3cm) shifted(1cm,0) ; > > > > draw r anglestriped (1,45,2) withcolor cyan; > draw b anglestriped (1,45,2) withcolor cyan; > > > > >draw p; > >draw b; > >draw r; > > > > label.llft("D", p) ; > > label.lrt("C", p) ; > > label.ulft("A", p) ; > > label.urt("B", p) ; > > label.urt("P", lrcorner r) ; > > label.lft("Q", llcorner r) ; > > label.top("M", urcorner r) ; > > > > \stopMPcode > > \stopmidaligned > > \stoplinecorrection > > \stoptext > > > > > > /Mikael > > ___ > If your question is of interest to others as well, please add an entry to > the Wiki! > > maillist : ntg-context@ntg.nl / > https://www.ntg.nl/mailman/listinfo/ntg-context > webpage : https://www.pragma-ade.nl / http://context.aanhet.net > archive : https://bitbucket.org/phg/context-mirror/commits/ > wiki : https://contextgarden.net > > ___ > ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___

Totally, a lot of food !

[NTG-context] Metafun : save memory content ?
Dear list, I’m doing animations in MetaFun, by simply using \startMPpage (…) \stopMPpage for each frame of the animation. Here is an example: https://youtu.be/yhxUbVQx9Uo (please note you can watch it in HD by adjusting the setting in YouTube). This works usually great, but when the number of objects to draw by page is large, the resulting pdf file could be huge, several gigabytes sometimes. Such huge files are difficult (sometimes impossible) to convert in jpeg files (I’m using Image magick for the conversion), necessary to do a mp4 movie. One solution is to do several pdf files, for example one by second; with this option, I can do 60 files of 30 pages, for an animation of 60 seconds (1800 frames for 1 minute). Everything is smoother this way, quicker to convert files. But in order to do so, I have to be able to describe each frame of the animation with the same set of instructions; so the position of an object at time t is described by an equation for example. But this is not always possible. If the animation is based on a random process, the position of an object at time t depends on his position at time t-1. I can still use this preceeding strategy by simulating the past at the begging of each second, starting with a unique random seed. So for example if I work on second 9, I begin by calculating the past from frame 1 to frame 240 (8*30) and then simulate time 241, draw frame 241, simulate time 242, draw time 242, etc.. This could be complicated to do, but is feasible. The drawback is that more I advance in time, the more computations I have to do at the beginning of each file. So to simplify things, one option would be to be save the state of some variables at some point in time, say t, in order to be able to access these informations at time t+1. So the strategy would be : % File second1.pdf for frame =1 to 30 : simulate position of objects ; draw the frame ; endfor; save the position of all objects ; % File second2.pdf Read (access) the position of all objects from second 1(after frame 30); for frame =31 to 60 : simulate position of objects ; draw the frame ; endfor; save the position of all objects ; Etc... Does someone has an idea of how to do such a thing ? I can read text file in Context with no problem and integrate them in the animation process with \startMPinclusions (…) \stopMPinclusions, but I did not find a way to write information from MetaFun to a text file. Is Lua the solution ? Thanks for any help !

The solution I use, different than the one offered, is to write in a « special » color the text I want to hide from the students. This permits me to have hidden texts in figures for exemple. Also, I do not calculate space required, this is automated ! Here is MWE : \enablemode[solution] \doifmode{solution}{ \definecolor[solcolor][magenta] } \doifnotmode{solution}{ \definecolor[solcolor][white] } \definedescription[solution] [color=solcolor] \starttext How many roads? \startcolor[solcolor] Professor note.\stopcolor \startsolution 42 roads. \stopsolution How much wood? \startsolution Alotta wood! \stopsolution No more questions. \stoptext So the color used when solutions are hidden are white on white, we can not see the text; but of course, if you change the background, you see the hidden text. So there is another step to the process (I usually do this only once a term); open the file in Acrobat, and find the option to delete hidden text. The text for which the color is the same as the background is really deleted. You can try to select the text in any pdf view/editor, the text is gone !

I already use blocks, but following your message, I tried to think differently. One solution would be to define a block for each course. Something like this (a working minimal example, redone in order this would be more easier to understand (I hope!) what I’m trying to do): % — \setuppapersize[S5][S5] \enablemode[Professor] \defineblock[ComplementTwo] \defineblock[ComplementThree] \setupblock[ComplementTwo,ComplementThree][ before={\page[yes]\setuppagenumber[state=stop]\setupheadertexts[]\setupbackgrounds[page][background=color,backgroundcolor=red]}, after={\page[yes]\setuppagenumber[state=start]}] \starttext % Let's process the summaries ; \beginComplementTwo Last course, we have seen A. \endComplementTwo \beginComplementThree Last course, we have seen B…. \endComplementThree \beginComplementThree Last course, we have seen C…. \endComplementThree % Let's begin course 1. This is course 1 : a lot of pages here about A! \page[yes] Let's begin course 2. \doifmode{Professor} { \useblocks[ComplementTwo] } This is course 2 : a lot of pages here about B and C! \page[yes] Let's begin course 3. \doifmode{Professor} { \useblocks[ComplementThree] } This is course 3 : a lot of pages here about D... ! \stoptext %— The only inconvenient of this solution if that I have to define 15 blocks (one for each week of the term): ComplementOne, ComplementTwo, .., ComplementFithteen… Another drawback of this is difficult to move one block form one week to another if I change something. Each block here correspond in fact to a summary of the previous course. So I have typically around 10 pages of summary for each course. The challenge is that the content of each course is not exactly the same form one term to another, so I have to move a page to the summary from one course to the other one, like in a given term, if teach about subject C in course 3 : \beginComplementThree Last course, we have seen C…. \endComplementThree , but next term in course 4: \beginComplementFour Last course, we have seen C…. \\beginComplementFour I have to manually change \beginComplementThree … \endComplementThree to \beginComplementFour … \beginComplementFour. But I will do this if I do not find another solution. Thanks again Hraban.

[NTG-context] Blocks inside a conditional mode.
Dear list, I have an error when I try to insert a block inside a conditional mode (but there is two nested conditional mode.. is this the problem ?). In my courses notes, I insert some blocks (named « Complement » in the minimal exemple below) when in « Professor » mode. This works fine, as shown in the first « \beginComplement … \endComplement » of my example below. But now I have to use another condition for some blocks, depending of the number of the current course. So I insert my block with a condition, here « CourseOne » : \enablemode[CourseOne] \doifmode{CourseOne}{ \beginComplement Another complementary slide. \endComplement } But this does not work : % tex error > tex error on line 1 in file /Users/fabricel/context/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv: ! TeX capacity exceeded, sorry [input stack size=5] % The problem can be summarized in this minimal non working example : % — MWE — \setuppapersize[S5][S5] \enablemode[Professor] \defineblock[Complement] \setupblock[Complement][ before={\page[yes]\setuppagenumber[state=stop]\setupheadertexts[]\setupbackgrounds[page][background=color,backgroundcolor=red]}, after={\page[yes]\setuppagenumber[state=start]}] \doifallmodes{Professor} { \keepblocks[Complement] } \starttext page 1 \beginComplement A complementary slide. \endComplement page 2 \enablemode[CourseOne] \doifmode{CourseOne}{ \beginComplement Another complementary slide but only for course number 1. \endComplement } \disablemode[CourseOne] page 3 \enablemode[CourseTwo] \doifmode{CourseTwo}{ \beginComplement Another complementary slide but only for course number 2. \endComplement } \disablemode[CourseTwo] \stoptext \stoptext % — MWE — Blocks and modes usually works fine for me, but here, I do not understand my error. Thanks for any help ! Fabrice. Note : in case this way of doing things seems a bit silly, here are more explanations. I do use mode « CourseOne » here because in the real life, the content in the condition « \doifmode{CourseOne}{ …} » is read in an external file, containing material for « CourseOne », « CourseTwo », etc. The setup is then, in the main file : % Main file : begin Bla bla bla ... \enablemode[CourseOne] \input ComplementMaterial.tex \disablemode[CourseOne] Bla bla bla ... \enablemode[CourseOne] \input ComplementMaterial.tex \disablemode[CourseOne] % Main file : end And in the « ComplementMaterial.tex » there is : % ComplementMaterial.tex — \doifmode{CourseOne}{ \beginComplement A complementary slide but only for course number 1. \endComplement \beginComplement Another complementary slide but only for course number 1. \endComplement } \doifmode{CourseTwo}{ \beginComplement A complementary slide but only for course number 2. \endComplement \beginComplement Another complementary slide but only for course number 2. \endComplement } % ComplementMaterial.tex — ___ 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 ___
