I hope it helps. Best regards, Robert Blackstone

How does \setupfloat work?
by Mark Szepieniec 29 Nov '14

29 Nov '14

I'm trying to set a default width for figures with \setupfloat. However, the command doesn't seem to be picking up the width specification, even though the manual indicates it accepts a width= argument: \setupfloat[figure][width=2cm] \starttext \placefigure{}{\externalfigure[picture.png]} \stoptext picture.png just gets inserted at its native size, rather than scaled to have the specified width. What am I doing wrong? (setting minwidth and/or maxwidth doesn't seem to work either) Thanks in advance for any assistance. Mark

drops: arbitrary path examples
by Peter Rolf 27 Nov '14

27 Nov '14

Hi, just two example documents I made while testing arbitrary paths with the 'drops' module. I plan to release the module soon, so this is not more than an appetizer. The code is still messy and unfinished, but I probably don't have the time to change that. Creating the examples took away all my free time. Take it as it is or just wait two more years.. Now, before I write down the download link some ** SERIOUS WARNING!!! I MEAN SERIOUS!!! SOMEWHAT SERIOUS!!! ** Both documents use a considerable number of graphics and can significantly slow down or even freeze your hardware. Open the examples at your own risk (especially with products from Adobe)! [whew, just lost 87% of the viewers here] A 2-3 years old PC should be able to handle the examples in acceptable time (judging from my hardware). But not only hardware power is needed, the software can be crucial too. Viewers tested so far (rating in front), all on Windows 7. [++] SumatraPDF: no problems, lightning speed and very good viewing quality (love it!) [+] PDFExchangeViewer: no problems, good speed (you can still watch how the graphics are stacked) and viewing quality (color management if off though) [--] Adobe Acrobat 9 Pro: 'out of memory' error after three pages (puddle), very slow speed, probably best viewing quality A real shame that the only viewer with problems is from the inventor of PDF. The 'pile' example from 2012 even crashed the viewer (v10), so this is still an improvement. Just let me know if there are any general problems. I will file a bug report then. Finally, the download link (you have been warned) :-D https://spideroak.com/browse/share/indiego/public/ConTeXt/drops/ Some technical info about the examples: [sigh, lost all my viewers right here] leafs: 150 leafs (six different colored bitmaps), resolution = 300ppi based on this graphic (thanks for sharing) http://openclipart.org/detail/10517/leaf-by-yves_guillou-10517 puddle: 200 MP graphics, resolution = 600ppi Only one shadow graphic is created for the main object (which is also reused then). Variation comes from scaling/rotation. The big 'drops' text in Copperplate is a MP graphic, but in theory it should be possible to add shadows to glyph paths. We will see. To ensure the readability of the few other text elements, both documents use the drops module to lighten the underlying background. A simple 'boxshadow' with a bright shadowcolor and a proper radius (maybe plus some offset) is all you need for that. This is a feature that I always wanted, way better than editing/creating the background areas by hand (correct position/size? a lot of try and error, a real pita). All done on the fly now, which is nice (me lazy). [OK.. all said, stopping now; so much text for a stupid link] Have fun, Peter

No number on first page
by Richard Sherman 27 Nov '14

27 Nov '14

Hi all, I have seen this question asked several times and not answered in a way that has worked for me. To suppress a page number on the first page, in LaTeX I would use \thispagestyle{empty} but I cannot find how to accomplish the same thing in ConTeXt. I have seen the suggestions \setupheader[1][header=0mm] which is not what is intended, and also does not result in page numbers on pages 2, 3, ..., and \noheaderandfooterlines which is also not successful, and doesn't seem like it should be, and \definelayout[1][header=0mm] \definelayout[2][reset] which doesn't work either. I'd like to 1. Have the header appear on each page and 2. Have no page number on the first page and 3, Have page numbers beginning on the second page which seems like it should have a simple solution, but after a couple of days of searching here and in the manuals I haven't been able to find it. A solution that puts a \page in somewhere fails, since I don't know when the second page will begin. Thanks much in advance, -Richard

Hi, The following example doesn't get the text after tufte citation back on grid. Using linecorrection helps ... but doesn't break across pages.

Trying to force a particular page sequence
by Gerben Wierda 26 Nov '14

26 Nov '14

I’m having trouble to produce a particular page sequence, all pages without page numbers: Title page (I have that) First left page with a text block in the lower left corner First right page with a statement centered, 1/3 down I’ve been trying working with \page, but what I get is Title page Empty page (first left) Right page with text (not yet in the lower left corner Left page with statement Right page with page number on top This is what I have in my prd_book.tex. What is a cleaner way to do this and also one that works? ;-): \starttext \start \startstandardmakeup \ss \hairline \start \blank[line] \switchtobodyfont[16pt]\bf \leftaligned{Foo}% \blank[line] \leftaligned{bar bar bar bar}% \blank[line] \leftaligned{Foo}% \stop \hairline \blank[line] \leftaligned{Foo bar foo bar bar bar bar}% \hairline \blank[line]\rightaligned{Gerben Wierda}% \blank[6cm]\start\leftskip=10cm\hairline\stop \rightaligned{2014}% \stopstandardmakeup \stop Copyright notice (should be lower left on first lefthand side page) \page[yes] \start \switchtobodyfont[16pt] ~%otherwise \blank does nothing \blank[6cm] \midaligned{Statement, centered first righthand side page} \stop \startfrontmatter

Defining and using font weights
by Andreas Schneider 26 Nov '14

26 Nov '14

Hello, I'm not able to figure out how I can make use of a font with "custom" font weights. I have a font that comes with "regular", "bold", "half-bold" and "ultra bold". I currently define the font like this: \definefontfamily[myfont][rm][myfont][sc=file:MyFontRegular,bf=file:MyFontBold] Which at least makes it possible to use the default font and \bf ... But simply adding something like hb=... or ult=... doesn't seem to cut it. So how would I define this font to be able to also use the half-bold and ultra weights? (preferably with a switch like \bf, \it, etc.) Best regards, Andreas

setupinmargin, setupmargindata ; page numbers ; fonts
by Richard Sherman 26 Nov '14

26 Nov '14

Hi all, I am having trouble with the control of fonts in \inmargin{} and in page numbers. I'm also having trouble with the alignment in \inmargin{}, and with font sizes generally. I've used what I know about \setupmargindata and \setupinmargin(and \setuppagenumbering). Below is an example that (almost) does what I want. The two or three problems I've tried and failed to solve are 1. control over the font size of the marginal note (rather than just \small; I want to choose a point-size) 2. control over the font and size of the page number. At first I used \setuppagenumbering[location={header, right, inmargin}] (yes, one of 'right' and 'inmargin' seems to be redundant). Getting a sans-serif page number, I assumed that \setupmargindata was controlling that, so I just switched to 'right', but my page number is still sans-serif. I've tried such things as [location={header, right}, style={normal, small}], as well as variants {\small}, {normal}, {\normal}, serif, \serif, etc. with not luck 3. in \setupmargindata and \setupinmargin, none of the 'align=' options seems to have any effect. More generally, I have trouble understanding how to specify font sizes in ConTeXt, how to set up the font and font-size of page elements, how to include comma-separated lists following 'style=', where even within braces all but the first option seems to be ignored (at least in my margin setup commands). I also can't figure out why, though the default (location) for \setuppagenumbering is {header, center} (and (font style) normal?), my page numbers default to sans, and when 'location=right' is specified without 'header', the page number is on the right in the ... footer (?!) Thanks for any help. -Richard \setuplayout[width=5in, header=.5in, footer=.5in, backspace=2in, location=right] \setupwhitespace[big] \setupindenting[none] \setupmargindata[location=left, align=outer, style={\ss \small}] \setuppagenumbering[location={header, right}] \definefontfamily [myfamily] [serif] [baskervaldx] \definefontfamily [myfamily] [italic] [baskervaldxita] \definefontfamily [myfamily] [bold] [baskervaldxbol] \definefontfamily [myfamily] [sans] [gillsansstd] \definefontfamily [myfamily] [mono] [CourierNew] \setupbodyfont [myfamily] \starttext ConTeXt is software\inmargin{A brief description of \ConTeXt} for typesetting high-quality documents.
