Shading transparency / missing linear_shade variant
by Eckhart Guthöhrlein 27 Jul '04

27 Jul '04

Hi all, experimenting with transparencies, I have obviously come to a limitation: color shading does not work for transparent colors. What I have in mind is a bar filled with a color gradient, starting from a certain (non-transparent) color and ending transparent, i.e. vanishing into the background. However, the transparent color appears just black. Furthermore, the shading variants for linear_shade do not correspond with those listed in the metafun manual, page 180. Variant 2 is missing and behaves like variant 3 should. Example: \setupcolors[state=start] \setupbackgrounds[page][background=color,backgroundcolor=red] \startMPenvironment[global] \definecolor[HeadLineColor][r=0,g=0,b=1] \definecolor[Transparent][r=1,g=1,b=1,t=0,a=normal] \stopMPenvironment \startreusableMPgraphic{test} numeric u; u=3cm; path p; p := unitsquare xscaled u yscaled u cornered (u/10); for i=0 upto 3 : linear_shade(p shifted(i*u,0),i,\MPcolor{HeadLineColor},\MPcolor{Transparent}); endfor; \stopreusableMPgraphic \starttext \reuseMPgraphic{test} \stoptext -- Eckhart

metaobj and transparent colors with \MPcolor
by Eckhart Guthöhrlein 27 Jul '04

27 Jul '04

Hi, I try to achieve transparently filled objects using the metaobj package. However, transparency is ignored completely in the output, I just get a normal white. Here is my test file: \setupcolors[state=start] \setupbackgrounds[page][background=color,backgroundcolor=red] \startMPenvironment[global] \definecolor[Durchsichtig][r=1.0,g=1.0,b=1.0,t=0.0,a=normal] \stopMPenvironment \startreusableMPgraphic{test} input metaobj; setObjectDefaultOption("Box")("fillcolor")(\MPcolor{Durchsichtig}); newBox.test(btex Transparent? etex) "filled(true)"; Obj(test).c=origin; drawObj(test); \stopreusableMPgraphic \starttext \reuseMPgraphic{test} \stoptext If I use the fillcolor as an argument to the object newBox.test(btex Transparent? etex) "filled(true)" "fillcolor(\MPcolor{Durchsichtig})"; I get error messages from the mpost run. So it seems that metaobj and \MPcolor don't like each other. Any ideas how to circumvent this problem? Regards, Eckhart

Fwd: (Classical) greek in ConTeXt/Gamma [please forward]
by Giuseppe Bilotta 27 Jul '04

Idris sent me this asking me to forward it. My reply follows. ===8<==============Original message text=============== Hi Giuseppe, I was digging in the archives and came across this; I don't think I ever saw this message (must have been busy at the time). Did you ever get an answer? I'm sure that editing the otp's will get you the result u wanted quite easily, but in the year since u wrote this u've probably figured that out already:-) Best Idri [NTG-context] (Classical) greek in ConTeXt/Gamma Giuseppe Bilotta ntg-context(a)ntg.nl Thu, 10 Apr 2003 15:40:35 +0200 Hello, I don't know if Idris is following the group (I hope he is), but anyway I have a couple of questions on the support for Greek in ConTeXt, Omega and thus also Gamma. The need is that of typesetting classical greek snippets in a latin (Italian, but could be English) context. I thought that ConTeXt+(e-)Omega would be the best thing in town, so I prepared a small test file: \usemodule[gamma] \mainlanguage[italian] \starttext Possiamo scrivere tranquillamente in italiano; questo non ci priva per\`o della possibilit\`a di scrivere in greco: vediamo subito l'alfabeto minuscolo e maiuscolo (notare come j dia \greek{j} e c dia il sigma di fine parola \greek{c}): \startgreek a b c d e f g h i j k l m n o p q r s t u v w x y z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z \stopgreek \`E ovviamente possibile usare segni diacritici come gli accenti (\greek{`a, 'a, =a}) o gli spiriti (\greek{<r, >w}); osserviamo come questi assumano automaticamente la posizione corretta nel caso di lettere maiuscole (\greek{`A, 'A, =A, <A, >A, Ai}) \stoptext While it seems to work pretty well most of the time, there seem to be some problems; I'd like to know where they arise from and if and how they can be fixed. The problems: Combination Doesn't give <r rho with spirit =A capital alpha with circumflex <A capital alpha with spirit Moreover, I don't know how to write the subscribed iota. My system is a MiKTeX 2.2 with (e-)Omega 1.15. Does anybody have an idea? -- Giuseppe "Oblomov" Bilotta ===8<===========End of original message text=========== My reply: Well, I'm pretty sure the bug is in the OTPs that come with Omega (which is pretty funny, considering that Yannis *is* Greek ...). I guess that when the rougher edges in Aleph are fixed we'll start correcting the OCPs :) -- Giuseppe "Oblomov" Bilotta

suppressing hyphenation and setlayerframed
by Eros Albertazzi 27 Jul '04

27 Jul '04

1- I would like to suppress hypenation in a text of a \startfiguretext within a \setlayerframed I am aware of the thread in jan 03 on the list and the fact that\setupalign[nothyphenated] (or \nohyphens) overshoot the right margin On the other hand I do not know where to put the align={left,nothyphenated,width} that was suggested in the reply here is the piece I work with: \setlayerframed[page][preset=righttop, column=1,line=30][width=\dimexpr((\paperwidth-2cm)/2),align=]{\getbuffer[b]} with the buffer: \startfiguretext [left][]{} {\externalfigure[t1][width=.2\textwidth]} ... <<<nohypened text>>... \stopfiguretext 2- still awfully raw on context I am looking for the options of \setlayerframed, list and meaning, command that is absent from manuals or web info-tools in details.pdf some examples are build with \setlayer[..][..]{\framed[..]{..}} what's the difference, if any, betwwen the two form?

Hi Henning, >===== Original Message From Henning Hraban Ramm <hraban(a)fiee.net> ===== >> Hans and others use SciTE. Does it provide Unicode/bidirectional >> support >> support? > >You can set it up to use UTF-8, but I don't think it supports r-t-l or >bidi. That's really too bad:-(( I actually have UniType Global Writer but it's really a pain to use for TeX source editing. On the other hand, it can be used to copy and past to WinEdt (where it will show up as utf-8 ascii). An all-in-one solution would be much better though. Now I'm a KDE lover myself;-) but doesn't GTK support bidi/rtl? So shouldn't SciTE support bidi right out of the box? In any case, I would still like to try SciTE if Hans' support files are available somewhere. Quick question: how does one activate utf-8? Best Idris

Disable Metapost rendering?
by SebastianSturm＠t-online.de 26 Jul '04

26 Jul '04

Hi, I really like ConTeXt's MP processing features, but as soon as I include more than five or six MP graphics in a document, typesetting slows down to a crawl. As far as I know, the PSTricks package has some option to only process a given range of the figures defined in the TeX file and reuse the existing output for the other ones. Is there a similar function in ConTeXt? Some global command like \donotrerender[1-n] would be great, a processing tag for each figure like \startuseMPgraphic{...}[rerender=no] would be perfect. Best regards, Sebastian Sturm
