[NTG-context] On figures and clipping
Hello,
I have some problems with the way to put clipped images in ConTeXt
documents; for what I can see the correct way to do it is via
something like:
\clip
[width=6.3cm,height=10.5cm,hoffset=0.5cm,voffset=1cm]
{\externalfigure[ciccione_03.pdf]}
Now suppose that I wanted to put the above thing zoomed 200%;
and here I have two problems:
(a) I can't seem to find the proper number to pass on to scale= or
factor= in the \externalfigure options
(b) AFAICS I need to scale all the clipping parameters as well.
Point (b) is particularly annoying; is there a way to pre-clip
an image, without touching the original file? It should be
possible to specify clipping area at inclusion time (LaTeX's
graphicx package can do that ...), and therefore in a
scale-independent way (this is especially important when the scale
factor is something like max or fit or broad).

For example, while .num are usually MP output, I could have other formats (embeddable by PDF) using those extensions. As long as I can specify [type=...] or [method=...], the extension should be left whatever it is. The problem arises because when the name of the included graphic is the same as the \jobname, extension is discarded. To be precise, two things are done: some extensions are discarded from the extensions searched, and then the extension of the file is wiped. While the first action is very wise (prevents output/input clash, so indeed tex, xml, pdf and dvi should be not searched in such a case), the second is not a good idea: after the suppression of the extensions, the inclusion should continue normally: we're safe from clash because the wrong extensions will not be searched.

On a very general basis, I would say that the best approach would be: Step 1: check for name clashes: * if name = \jobname: (a) if extension = \jobsuffix or output suffix (dvi, pdf), quit parsing (b) if no extension, remove jobsuffix and output suffix from list of searched extensions. Step 2: if extension is specified, and no method is specified, set method to the one associated with this extension, if there is one. Step 3: check if file exists; * if we have a full name, try to open the specified name.extension, with the specified method * if the file is not found, and no extension was specified, look for all the known extensions (except the ones forbidden by Step 1, point b); if a method/type is specified and it has a default extension, start looking from that extension Or something like this ... -- Giuseppe Oblomov Bilotta ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

[NTG-context] Backgrounds
Hello, I would like to discuss a few points about backgrounds (\startbackground ... \stopbackground). First of all, it would be nice to have background classes, so that I can have different backgrounds for different things without having to reset it each time. (Think \definebackground[this][options=values], \setupthis, \startthis ... \stopthis, as usual.) The second point is about the splitting capabilities in backgrounds. This is incredibly nice to have, but needs a little finetuning, IMO: it should be possible to specify whether the various options that concern the border of the background (i.e. background corner, frame, frame corner, etc) should act at split time or not; example: assume that I set my background to have a frame (frame=on) If the background gets split across pages, I get two boxed text: the first in the first page, the second in the second page. Instead, to show that the block continues on the next page, it should be possible to turn this off. I suggest options like: splitframe, splitframecorner, splitbackgoundcorner analogous to topframe/bottomframe and the like, which defines the behaviour of frames and angles in the split area. Moreover (now I'm getting picky, but while we're at it ...) it would be nice, even for generic framed text, to be able to specify the behaviour of each single corner separately (say, top left and top right rounded, bottom left and right rectangular). -- Giuseppe Oblomov Bilotta ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

Also, setting a largish offset covers the text that precedes the background, and this isn't nice at all. I think that textbackgrounds and backgrounds serve different purpouses.

Yup, after a little debugging I came to the same conclusion, but I
still it's incorrect behaviour. It's correct that it removes the
jobsuffix from the figuretypes to be searched, but it should still
try and look for the figure, after the change.

HH there is a trick for that, but i cannot find it right now; however, the

Yup, floatcaptions can do it all, nice. Now the question is: is it
normal for the combination to stick to the left margin? Shouldn't
it be centered horizontally? I can achieve the effect by
surrounding it with \midaligned{...} (i.e.

[NTG-context] Displayed material, again
Hello list,
I wish to bring the discussion again on displayed material.
Display material is material that conceptually belongs to a
paragraphs but typographically breaks it. After the display, the
paragraph can continue or not. In ConTeXt, there are many things
which should be considered displayed material: formulas,
enumerations and other itemgroups, quotations, etc. Every
start/stop pair that begins a new paragraph should actually be a
displayed area. In ConTeXt, one can achieve such result by using
[intentnext=yes] or [indentnext=no] on a case-by-case basis,
depending on whether the start/stop pair is supposed to start a
new paragraph or not. Of course, this manual way to do the thing
goes against the general principle that the computer is supposed
to do as much of the job as possible, by itself. I therefore wish
to urge Hans to implement a new indentnext option, auto, which
should give a behaviour similar to the one shown on this example:
=== BEGIN displayed.tex ===
\setupindenting[medium]
\definestartstop[display][before=\initdisplay,after=\terminatedisplay,style=italic]
\def\initdisplay{\ifvmode\else\endgraf\noindent\fi
\bgroup\advance\leftskip2\parindent\advance\rightskip2\parindent\ignorespaces}
\def\terminatedisplay{\par\egroup\afterassignment\checkifpar\let\ispar=}
\def\checkifpar{\ifx\ispar\par\else\noindent\expandafter\ispar\fi}
\starttext
The purpouse of this document is to practically show how display
material should behave: display material is material that
conceptually belongs to a paragraphs but typographically breaks it
After the display, the paragraph can continue or not.
We now quote Knuth:
\startdisplay
\input knuth
\stopdisplay
and continue the paragraph right after. The following quote will
instead end the paragraph:
\startdisplay
\input tufte
\stopdisplay
This text belongs to a different paragraph: note that it's being
indented (differently from the previous snippet). This paragraph

a quotation (display material at the beginning of the paragraph)
and have some text after~it.

The paragraph-wise behaviour of \initdisplay and

[NTG-context] Columns in itemizations
Hello, following up to a recent post on comp.text.tex I'd like to bring forth an enhancement request for itemgroups: in the current implementation it is not possible to set up itemgroups to use the non key=value pairs settings. IOW, one cannot say \defineitemgroup[myitems] \setupmyitems[each][A] and have the items come up numbered with capital letters. Some keywords (like: joinedup) work, some others (the numbering type ones, for example, or columns) don't work. For what I can see by looking at the code, this depends on these settings being looked for *not* when setting up the itemizations, but in the actual moment when the \startitemgroup is issued (this is for example the case for columns). Enhancement request: allow all keywords to work. I think the most straightforward way to implement this is to simply store the keywords and put them as default values when \startitemgroup is called (this would even, I suspect, simplify the handling of the itemgroup setups ...) -- Giuseppe Oblomov Bilotta ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

[NTG-context] Using Fraktur (and Gothic and Calligraphic) fonts in ConTeXt
Hello,
I just wanted to report the conclusions I reached after the
hoop-jumping I had to go through to be able to use Fraktur in
ConTeXt, especially in math environments: it seems that the \frak,
\goth, \cal font switches are ignored in math mode (which is
somewhat ridiculous, considering that this is where they are used
more often).
A workaround (stolen from the old math module) is to define
\def\fraktur#1{\ifmmode\@EA\text\fi{{\frak#1}}}
\def\gothic #1{\ifmmode\@EA\text\fi{{\goth#1}}}
\def\caligraphic#1{\ifmmode\@EA\text\fi{{\cal #1}}}
and use \fraktur{a} instead of {\frak a}. This has the
disadvantage that you cannot set Fraktur as the (math) font for a
complex math construct. Can this be fixed, please?

HH eh .. not sure if i understand this; some global switch would do most of HH the trick i assume Nope. As an example, assume the displayed material in question is a quotation: changing a global switch will make all/none of the quotations be distinct paragraph. This is not good, because wether or not the quotation is a part of the paragraph or not depends from the quotation and its context, so the user should be able to decide when new pars are started and when not, for each single quotation. And since the standard way to get new pars in TeX is by putting empty lines, why should it be different for displayed material? I don't think there should be any need to look back or ahead. Just don't force a new paragraph before and after each displayed item. Let the user choose, the standard way(s). HH well, since i want to be able to control consistency, i do need to look HH back; say that the design says: no empty lines (parskips) before something, HH then i need to configure that particular display instance to ignore the HH (possiibly already applied) parskip; keep in mind that it's not always the HH author who decides that somethign should start like a new paragraph; I'm not sure I understand this.

This category includes itemizations (all itemgroups, actually), formulas (not inline, of course), quotations, etc. HH hm, i like a more general view on 'display': anything that stands out in HH the text stream, being par or not, this is why it should be configurable HH (even tex is a bit fuzzy about it, since display math is used for both HH in-par or between par math) That's precisely my point. Contrary to TeX, ConTeXt always forces new paragraphs for displayed material: each displayed material is always considered a distinct paragraph, and thus always terminates the previous paragraph and begins a new one after its end. Of course between par displays (i.e. displays surrounded by empty lines) should be distinct pars, but this should not be enforced on all displays (as it it by ConTeXt, currently). -- Giuseppe Oblomov Bilotta ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

Hello, I'm going to bring the discussion back to a sore point that really needs to be cleared.

Assume for example that the paragraphs are set to have an indent (\setupindenting[medium], for example) and that the indentnext option is set to true. In this case some text after would only be indented in cases (3) and (4), but not in cases (1) and (2), since in cases (3) and (4) it starts a new paragraph while in cases (1) and (2) it is part of the previous paragraph.

Re[2]: [NTG-context] About itemize
HH first of all, we're not dealing with a bug, it's a feature; so, if some HH other behavior is wanted, it should be an option of extension to existing HH mechanisms, nog a replacement. HH there is one thing we should keep in mind: naive users are not always aware HH of tex's empty line == par, so this is why \start/\stop things are HH consistent in absense or presense of them; HH distinguishing between display and semi-display is therefore not that HH trivial, and the best option is separate environments, like HH\startquotation ... \stopquotation HH (or \startdquotation ... \stopdquotation for display quotation) versus HH\startpquotation ... \stoppquotation HH for an in-paragraph one (like we have with formulas, see core-mat.tex) HH that way, one knows what to expect, since it's clear from the coding, and HH not from a (forgotten, or accidental) empty line HH another option is to have a dedidated environment HH \startinparagraph ... \stopinparagraph HH or \startcontinue ... \stopcontinue HH which nills the surrounding whitespace and inhibits the next indent. (this HH should be not that hard to implement) This latter alternative sounds awfully 'redundant' (too much code for a simple thing); the first sounds somewhat better, but the best solution IMO is to have an option/conditional \obeypars or something like that. When true, empty lines after startstops denote paragraph and lack of empty lines denote remaining in the same paragraph; when false, current ConTeXt behaviour is kept. Maybe we may want to have a per-startstop option (obeypars=true,obeypars=false) together/in place of the global \obeypars/\noobeypars (or \obeyparstrue/\obeyparsfalse). Let's say that the best thing (again IMO) is to have a global option, overridable in each startstop: the obeypars key in startstops would then accept the values true (force true), false (force false), default (behave according to the global setting). Does this sound sensible? -- Giuseppe Oblomov Bilotta ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

Hello,
I just read a post on comp.text.tex asking how to make This page
intentionally left blank in LaTeX. There, it's a matter of
redefining the \cleardoublepage comman; I assumed that ConTeXt had
some kind of built-in hook to do that, but I found that it is not
so; the command that ejects a blank page when needed is
\ejectdummypage, but there is no way to configure it to put
something on that page. Could the page ejecting mechanism be
slightly improved, with a \setupdummypage[...] command that
defines what has to be done with the dummy pages?
HH \page[blank] : no ornaments
HH \page[empty] : empty page, no page break first
HH \page[makeup] : also empty, forces a page break first
HH so,
HH \page[yes,empty]
HH is first flushing the current page, and then issuing an empty one
HH so, what you want in addition is something
HH \startstandardmakeup[doublesided=no]
HH \labeltext{blankpage}
HH \stopstandardmakeup
HH or so, but then accessible by keyword? (\page[makeup,text] or so)
No, I was thinking more of events like
\page[odd]
which flushes the current page if we are on an even page, but
flushes the current page AND addes a blank even page. This blank
even page cannot be configured to be nonblank, and that's what I
want.

i come back to the tooltips later
JUM before i forget it, i would like to give here an additional idea
JUM about this topic:
JUM IMO, the whole thing should be more general, maybe by calling it
JUM 'balloons' or 'balloonwidget'. The usage in \footnote, \tooltip or
JUM \cite is only an instance of the more general balloon-object.
JUM For example, i would like to use such a ballon-widget as a
JUM dropdown-menu in an interactive document that contains
JUM a list of chapters, ...:
JUM \balloon[placement={below,centered},
JUM frameclass=DropMenu,
JUM opendirection=down,
JUM openaction=OnClick]
JUM {Chapters}
JUM {\placelist
JUM [chapter]
JUM [criterium=all,
JUM alternative=a,
JUM pagenumber=no,
JUM interaction=all]}
JUM and tooltips are then:
JUM \defineballoon[tooltip][...]
I have a draft implementation for this.
By now, the only thing
that can be configured is the framecommand. I decided to use this
instead of a frameclass because it's even more flexible
(with frameclass, you need to define a different frame class for each
different ballon type, even if changes are small; this way, small
changes can be applied more easily when defining new tooltips.)
Put the following code in your cont-new.tex file or in your
cont-loc.tex file (whichever you use for customizations), until
Hnas decides to pass it to the core. I hope to come out myself
with more customization options, but I would have to study fields
and co. Maybe I'll leave that to Hans though.
BTW, your stuff seems to more oriented towards what Hans called
helps rather than tooltips, but I don't know much about this
feature.
Anyway, here's the code for custom balloons. Hope I didn't
reinvent the wheel ...

JUM Commands that currently support framed-parameters could then
JUM support a parameter framedclass=name
That's exactly what I mean.
(2) add tooltip classes
JUM in the other mail-thread we agree that for tooltips the whole word
JUM should be an active area. IMO, this is not the best solution. If we
JUM can use tooltips for footnotes or bib-entries in the future, those
JUM elements will show a mark/symbol in the text, but for normal tooltips
JUM the problem is that nothing shows the reader of the document that
JUM there is a tooltip available. I think it is not a common practice to
JUM read a document and scan constantly the words with the pointing
JUM device. Thus, there should be also for normal tooltips a symbol or
JUM something else that indicates the tooltip.
If we have tooltip classes, these options (including size and
fitting of the active area to the content) could be configured per
class.
