Re: [NTG-context] Too much spacing in math mode between 'f' and 'l' (MkIV only)

Is it a bug? > Spacing between letters when treated as individual variables is always a bit fishy. In this case the math mode suppresses the fl ligature, which seems to be present in the font, whence the spacing is off. Something like \starttext \math{{\it flow}_1} \stoptext will help ConTeXt treat it as text and improve the spacing (and in this case make use of the fl ligature). Define \def\flow{\text{\it flow}} if you just want to say \starttext \math{\flow_1} \stoptext Severin

tikz picture is placed align left-upper corner
by Gao Ya'nan 03 May '11

03 May '11

I draw a figure by tikz but found it is not in the middle but a little left of the page, and then I wrote a piece code and impoved my view. And I tried to add some parameters to put the figure in the middle but failed. Thanks for any tips and test code is below. \usemodule[tikz] \usetikzlibrary[positioning, shapes, shadows, arrows] \usetikzlibrary[backgrounds] \starttext \placefigure[here][fig:pci]{PCI System}{ \framed{ \hbox{ \tikzstyle{abstract}=[rectangle, draw=black, rounded corners, fill=blue!40, drop shadow, text=white, font=\small] \tikzstyle{cache}=[rectangle, draw=black, rounded corners, fill=green, drop shadow, text=white, font=\small] \starttikzpicture[background rectangle/.style={draw=blue}, framed] \draw[help lines] (-5, -4) grid (5, 1); \node (Processor) [abstract, rectangle split, rectangle split parts=2] { {Processor} \nodepart{second}Cache }; \node (AuxNode01) [below=of Processor] {}; \node (Coherency) [cache, left=of AuxNode01] { {Cache Coherency} }; \node (L2-Cache) [cache, right=of AuxNode01] { {Cache} }; \stoptikzpicture } } } \stoptext

Re: [NTG-context] modules with no author

Positional graphics (MetaFun)!
by Verhaag, G.C.H.M. 03 May '11

03 May '11

Hi, Inspired by the examples given in the MetaFun manual (Oct. 2010) I tried a few, but I can't get them working! I'm specially interested in the 'Anchors and layers' (p.257, screen version!) feature. I typed in the MetaPost code as given on page 260, defined the anchors, but no circles and lines appear in the resulting pdf-file. Well I assume it must be something trivial. Anybody any idea? P.S. I use ConTeXt ver: 2011.03.30 11:21 MKIV fmt: 2011.3.30 int: english/english Regards, Gerard Verhaag

Line break in verbatim
by Aditya Mahajan 03 May '11

03 May '11

Hi, Why does verbatim text not line break properly. \setuppapersize[A5] \showframe \starttext % hyphenate is not the right word here; but illustrates the problem \type{a very very long line to see if it hyphenates or not, that can require a lot oftyping phew}. \stoptext Also, it is possible to completely prevent line breaks for \type.

I was indeed using the system's libpng, my bad. Strange though, that this comes out just now. Anyhow, thanks. Adam

Re: [NTG-context] simpleslides + combinepages != qpdf

Right, I have a feeling that this is MetaPost related, hence the random problems with different styles. I can reproduce this now without simpleslides too, using only metapost. Here's a minimal example: Get logo_ignite.mp from: http://pastebin.com/raw.php?i=VqvcWniu % slides.tex \startreusableMPgraphic{ignite} input logo_ignite; \stopreusableMPgraphic \starttext \reuseMPgraphic{ignite} \stoptext %handout.tex \setuppapersize [A4][A4] % or [A4,landscape][A4,landscape] \setuplayout [header=0pt,footer=1cm,backspace=1cm,topspace=1cm,width=middle,height=middle] \setupfootertexts [presentation---\currentdate\space---\space\pagenumber] \starttext \combinepages[slides][nx=2,ny=3,frame=on] \stoptext context slides.tex && context handout.tex && qpdf --linearize handout.pdf out.pdf results in: object stream 21 (object 31 0, file position 1547): unknown token while reading object (nullnullnullnull) ConTeXt ver: 2011.05.01 12:50 MKIV fmt: 2011.5.2 int: english/english mkiv lua stats > luatex banner - this is luatex, version beta-0.71.0-2011050213 (rev 4233) Adam

I've tried a "Hello world" file and also a non-simpleslides presentation tex file, all of them work. So it seems it's simpleslides and yeah, you where right, it's the styles. I'm using "Split" for my presentation and as for the minimal I've provided BigNumber, both fail at some point. Using style=default, does not have this problem with qpdf. I'm still trying out different styles and different slide content ... Adam
