Re: [NTG-context] clipping problem
Just as a reminder for an unsolved problem :)
I also tested this on contextgarden, with faulty result. Same with
\clip[hoffset=64bp,voffset=64bp,width=64bp,height=64bp]{\reuseMPgraphic{cliptest}}
So it doesn't look like a rounding problem.

Hi,
I have some png-graphics, where several (equal sized) icons are arranged
in array form. When I cut out an icon, I get the icon gfx plus a very
small part from the surronding icon(s). The attached file shows, that
the same problem occurs when using a vector based graphic.
Normally I use imagemagic to seperate such files into single gfx, so
this is not a serious problem for me. But if this is a bug, it should be
fixed (or if I have missed something, let me know).

This can be done neatly if one remembers that label is equivalent to
draw thelabel. Hence,
p := textext(\AXIS{z}{3}{Optical Size});
label.top(p,z[13]) rotatedaround (z[13], angle(z[5]-z[1]) ) ;

Hi,

math-eul.tex says
%D This used to be very hackish; it brought in text
%D accents from the well-matched Bitstream Charter.
%D But now, these characters don't exist. I would prefer to pull
%D them from the text font, but I don't know how.
%D Instead, I'm just pointing to null characters!
:-(
This is how eulervm.sty defines these characters for T1 encoding.

\DeclareMathAccent{\ddot}{\mathalpha}{operators}{4}

I do not know what is the equivalent of 'operators' family in context.
Any idea how to pull them out of the text fonts?

I guess that I should read this as please comment your code better next time pair diag[]; diag1 = (2,1.25); diag2=(10,-2.5); I used diag1 to define the translation between the front and the back face and diag2 to define the translation between the first and the second cube. for i=0 upto 1: for j=0 upto 1: for k=0 upto 1: for l=0 upto 1: z[i+2j+4k+8l] = (((i,j) scaled a) shifted (diag1 scaled k) shifted (diag2 scaled l)) scaled u; endfor; endfor; endfor; endfor; i is the counter for x axes: i=0 means left, i=1 means the right point j is the counter for y axes: j=0 means bottom, j=2 means the upper point Original point will thus have coordinates (i,j) and we create 4 points (sorry, I'm leaving out the braces): z2---z3 | | z0---z1 k is the counter for z axes: z=0 means the front face, z=1 means the back face The original point(s) are translated for diag1: shifted (diag1 scaled k): if k=0, no translation is present, if k=1 it's translated to the back. You then get additional 4 poins, namely z6---z7 | | z4---z5 traslated for vector diag1 to form the back face. Finally, you use the counter l for the first and the second cube. shifted (diag2 scaled l) doesn't do anything if l=0 (shifted (diag scaled 0) is same as shifted (0,0) which is identity) and translates the first cube into the second one when l=1. z[...+8l] will number the points from 0 to 7 (depending on i,j,k) when l=1 and from 8 to 15 when l=1, so you get the same points with index of z increased for 8 if you're in the second cube. for i=0 upto 3: draw z[4i]--z[4i+1]--z[4i+3]--z[4i+2]--cycle; this will draw: - z0--z1--z3--z2--cycle (first cube, the front face) - z4--z5--z7--z6--cycle (first cube, the front face) - z8--z9--z11--z10--cycle (second cube, the front face) - z12--z13--z15--z14--cycle (second cube, the front face) % small diagonals draw z[i]--z[i+4]; draw z[i+8]--z[i+12]; this will draw z0--z4, z1--z5, z2--z6, z3--z7: diagonals connecting the front face with back face and same for the second cube, only for z[index+8] draw z[i]--z[i+8]; this will connect the fron face of the first cube with the fron face of the second cube (+8) draw z[i+4]--z[i+12]; same, bu for the back face; this could be done with the first definition already if 'i' went from 0 to 7 instead from 0 to 3. label (textext(Sans Serif),.5[z[3],z[4]]) ; z3 is the upper right point in the front face and z4 the lower left point in the back face, .5 is the point in the middle then. label (textext(Serif),.5[z[11],z[12]]) ; z11 and z12 are the same points (3+8 and 4+8) on the second cube. Hope that helps, Mojca (Asymptote does some conversions directly since it supports 3D, but I never worked with it, most probably because it's not integrated so well with ConTeXt, although it seems a bit more optimistic in the last time.) ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context

[NTG-context] where have the ol' dam' font was Re: urw garamond for distribution
Hi to all, I asked to the list how to know which font are installed on my machine. The reply was that I cannot guess this info from inside tex, but it should be possible to grasp information starting form the distro I use. (I'm using TeXShop, with Gerben distro on macosx) So, I was tinkering: can anyone suggest a list of widely used font name so that at least I can try to call them from inside ConTeXt and see if they are present or not?
