Hi ConTeXt mailing list,
I am using the extensible arrows and I am not really satisfied with the looks of it.
The most important issue I have is that the vertical spacing is too much. You can see this in the attached picture: the left arrow is using \xrightarrow{\neq a} and the right arrow is using \stackrel{\neq a}{\longrightarrow}. I think the right one (with stackrel) looks more natural. Is there a way to setup the vertical spacing?
Another thing I noticed is that the line is not very consistent. This might be a font issue (I am using Euler). Luckily, the inconsistent overlap is barely visible when printed.
Thanks again!
Groetjes, Joshua
Hello, You can also use MetaPost to render math stackers, rather than relying on TeX constructs and any particular font. For example: \useMPlibrary[mat] \definemathstackers [mp] [alternative=mp] \definemathextensible [mp] [leftarrow] ["2190] \definemathextensible [mp] [rightarrow] ["2192] \definemathextensible [mp] [leftrightarrow] ["2194] \definemathextensible [mp] [longleftrightarrow] ["27F7] \definemathextensible [mp] [rightoverleftarrow] ["21C4] \definemathextensible [mp] [underbrace] ["FE3DF] \setupbodyfont [dejavu-condensed,12pt] \starttext $\rightarrow{≠a}$ \stoptext Furthermore, the MP arrow can be tuned \startMPinitializations ahlength := .5EmWidth ; ahvariant := 1 ; % dimpled straight \stopMPinitializations as can line widths, etc. Alan
