Thanks, nice scale. How about the arcs and the text between them? Regards, Magnus On Mon, Oct 7, 2013 at 11:57 AM, Alan BRASLAU wrote:

2. I would like to use the \followtokens macro from within metapost. How can this be achieved? Specifically, I trying to draw a rainbow-like figure with text "between" the colors.

I am not sure what you mean by a rainbow-like figure. However, for rainbow-like colors, I use the following MP code, based on the standard resistance color code scheme. The function rainbow(f) returns a rainbow spectrum color based on the fraction f running from 0 to 1.

% standard resistance color code: rainbow sequence color resistance_color[] ; string resistance_name[] ; resistance_color0 = (0,0,0) ; resistance_name0 = "black" ; resistance_color1 = (165/255,42/255,42/255) ; resistance_name1 = "brown" ; resistance_color2 = (1,0,0) ; resistance_name2 = "red" ; resistance_color3 = (1,165/255,0) ; resistance_name3 = "orange" ; resistance_color4 = (1,1,0) ; resistance_name4 = "yellow" ; resistance_color5 = (0,1,0) ; resistance_name5 = "green" ; resistance_color6 = (0,0,1) ; resistance_name6 = "blue" ; resistance_color7 = (148/255,0,211/255) ; resistance_name7 = "darkviolet" ; resistance_color8 = (190/255,190/255,190/255) ; resistance_name8 = "gray" ; resistance_color9 = (1,1,1) ; resistance_name9 = "white" ;

def rainbow(expr f) = hide(numeric n_ ; n_ = (abs(5f) mod 5) + 2 ;) (n_-floor(n_))[resistance_color[floor n_],resistance_color[ceiling n_]] enddef ;

I have the fonts and they are reported as mathdesigngd by the mtxrun fonts script -- sorry if this was unclear. How do I proceed from here? Regards, Magnus On Tue, Oct 8, 2013 at 5:30 PM, Wolfgang Schuster < schuster.wolfgang@gmail.com> wrote:

Hello list,

Long term (silent) on-and-off user with two issues that require some support:

1. How can I use the Mathdesign GD math font in ConTeXt? I use simplefonts to load Adobe Garamond Pro, but mathdesigngd (name as reported by mtxrun fonts script) is somehow not found. At this time I fallback to ugly solutions with \text in math mode. And yes, I know about type-imp-mathdesign.mkiv, but obviously I'm not qualified enough to get it right.

Minimal (not) working example:

\usemodule[simplefonts]

\setmainfont[Adobe Garamond Pro] \setmathfont[mathdesigngd]

\starttext I want \m{x^2+y^2=z^2} in my text, and $\alpha\beta\gamma$ too. \stoptext

The Mathdesign fonts aren’t part of the normal installation and you have to add “--fonts=mathdesign” or “--fonts=all” when you call first-setup.sh|bat.

With mathdesigngd (which is intended to complement Adobe Garamond Pro, and the one that I want), I get fonts > typescripts > unknown library 'mathdesigngd' in the output.

This should work (can’t test it myself):

\usetypescriptfile[mathdesign]

\usemodule[simplefonts]

\setmainfont[Adobe Garamond Pro] \setmathfont[mathdesigngm]

\starttext I want \m{x^2+y^2=z^2} in my text, and $\alpha\beta\gamma$ too. \stoptext

Wonderful, this is really appreciated. Regards, Magnus On Tue, Oct 8, 2013 at 7:38 PM, Wolfgang Schuster < schuster.wolfgang@gmail.com> wrote:

1. It’s possible the math design fonts uses different file name than the ones context expects and this is the cause for the error message.

2. Math for Adobe Garamond isn’t supported yet by context.

I can take a look why math design fails and fix but not today because it takes a while to check all files.
