Re: [NTG-context] Cover of ePub

2015-08-07 Thread Henning Hraban Ramm

I overlooked one thing:
With the minimal example ConTeXt’s export doesn’t create a cover.xhtml, but in 
my project it does.

Re: [NTG-context] Text around a figure in a framedtext

2015-08-07 Thread Otared Kavian

Hi,

You should use the same width if you want to obtain the same result (by the 
way, you have to say also \stopframedtext in your source file):

\startframedtext[width=\textwidth]{
\placefigure[right,none]{}{%
 \startMPcode
  draw unitsquare scaled 2cm ;
  \stopMPcode}
\input knuth.tex }
\stopframedtext

Best regards: OK

[NTG-context] Cover of ePub

2015-08-07 Thread Henning Hraban Ramm

Hi again,

I'm trying to define a cover image for my ePub using the documented „firstpage“ 
setting of \setupexport.

While it works in my minimal example below, it fails in my project structure; I 
tried to move \setupexport into project, product and component to no avail.

%
\setupbackend[export=yes]
\setupinteraction[
state=start,
color=,contrastcolor=,
title={ePub Test},
subtitle={ConTeXt},
author={Hraban},
]
\setupexport[
bodyfont=12pt,width=470pt,
hyphen=yes,
firstpage={koe}, % works here, but not in environment
]

\starttext

\startchapter[title={Knuth}]

\startparagraph
\input knuth
\stopparagraph

\stopchapter

\stoptext

Partially replying to myself.

After defining a paragraphs environment, I have to set them up, not to
define them again.

So the code above should read:

\defineparagraphs[timesdroid][each][n=2, before=\blank]
\setupparagraphs[timesdroid][1][style=\newtimes]
\setupparagraphs[timesdroid][2][style=\droidserif]

But I don’t know what is wrong is foregroundstyle in xtables.

Many thanks for your help,


Pablo

Thank you Alan. setrange is the key I had not tried and I will be more careful

This may not be the proper way to ask, but it is related to the topic: how to

[NTG-context] issues with typeface selection

2015-08-07 Thread Pablo Rodriguez

Dear list,

I have the following sample:

\definefontfamily[timesnew][serif][FreeSerif]
\definefontfamily[droidserif][serif][Droid Serif]
\setupbodyfont[palatino, 12pt]
\starttext
I want to have \type{\timesnew\ttfx} and \type{\droidserif\ttfx}
in each cell, but \type{foregroundstyle} doesn’t seem to work
(compilation crashes).
\startxtable
\blank
\startxrow
\startxcell \ConTeXt\ is awesome!\stopxcell
\startxcell \ConTeXt\ is awesome!\stopxcell
\stopxrow
\stopxtable
\blank
Typeface selection doesn’t seem to work even with paragraphs:
\defineparagraphs[timesdroid][each][n=2, before=\blank]
\defineparagraphs[timesdroid][1][style=\newtimes]
\defineparagraphs[timesdroid][2][style=\droidserif]
\starttimesdroid
\ConTeXt\ is awesome!
\timesdroid
\ConTeXt\ is awesome!
\stoptimesdroid
\stoptext

All I need is to be able to have a text with a given font family and a
smaller font size on the left and the same text with the same font size
but another font family on the right.

I have failed with both xtables and paragraphs.

Wnat am I missing in each case?

Many thanks for your help,


Pablo

Hi,
The following code (Metafun documentation, thanks again Hans !) is fully

Thus, the only invocation \startMyText ... \stopMyText, \startMyText ...
\stopMyText... this return Définition 1, Définition 2 ...

Hi Aditya,
Thank you, I have already thought of this solution, but I do not
know to use with the environment that I created.

There was lot of work in W3 recently dedicated in CSS for paged media. Even
further development of mature XSL-FO has been discontinued in favor of
HTML+CSS. 

http://www.smashingmagazine.com/2015/01/designing-for-print-with-css/

And many publishers believe this is the future. While many features are not
available in browsers yet, there are corresponding JavaScript
modules/polyfills which mimic the intended rendering so nothing stops the
publishing industry from migrating their workflows into the new standards.

One of such JavaScript framework is vivliostyle.js - http://vivliostyle.com/

Back to the original question, enabling/disabling font features can be done
using CSS font-feature:
http://www.w3.org/TR/css3-fonts/#font-rend-props

Re: [NTG-context] m-graph read data and plot

2015-08-07 Thread Alan BRASLAU

You have two problems:

1) gdraw (4,1)--(7,1);
has a unique ordinate, so graph will fail in this case if you do not
explicitly set the range.

2) You have to take care with your choice of loop variables in MP not
to run into conflicts those eventually used in macros. Also, as Hans
indicated, you do need to declare that a is an array, as in
numeric a[];

Here is a MWE

\enabletrackers[metapost.showlog]
\usemodule[graph]
\startMPpage[instance=graph,offset=3mm]
  draw begingraph(5cm,5cm);
numeric a[];
gdata("data.d", v,
  for j=1 upto 3:
a[j]:=scantokens v[j];
  endfor ;
  );

setrange (whatever,0,whatever,2);
gdraw (a2,a1)--(a3,a1);
  endgraph;
\stopMPpage

[NTG-context] ebooks

2015-08-07 Thread Hans Hagen


Hi,

In

http://www.tomsguide.com/us/amazon-kindle-paperwhite,review-2967.html

I read under "Advanced Typesetting"

... improved character placement and spacing, with advanced kerning and 
ligatures ...books with this enhanced typesetting are not easy to find


which makes me wonder: how can an html file (just a char stream) 
determine in an epub that kerning/ligaturing is disabled By default?


(I can imagine a css enabling something but still ...)

Hans
