Math & Science ⇒ Extended Vector Arrow

[tommytex]

thank you cgnieder!

i really like this
at least for me it is a beautiful vector arrow...
i changed the numbers a bit but generally your code does the job!

Code: Select all

% changed definition:
\makeatletter
\def\overvect@#1#2#3{\vbox{\ialign{##\crcr%
 \noalign{\kern.4pt\nointerlineskip}#1#2\crcr%
 \noalign{\kern1.5pt\nointerlineskip}$\m@th\hfil#2#3\hfil$\crcr}}}
\makeatother

Glad I could be of help

BTW: your picture nicely shows a reason for the default values: the raised arrow destroys the leading when it is used inline.

Actually, what about having harpoon arrows with single pointed side rather than double pointed arrow ? cgnieder: how would one retain leading if the vector arrow is chosen to be the modified vertically shifted one ?

You can't, at least not in a satisfying way. These are choices:

• Don't modify the arrow position and retain the leading
• Modify the arrow position like we did and live with the fact that the vector then is to large for inline uses
• modify the height of the arrow in a way that it overlaps with the space above; this might work in many cases but could also overlap with letters from the line above...

well there is one other method:

make the letters under the arrow be smaller than normal size and put the arrow on top...this might work quite well i suppose....

What about the overlap of the vector arrow? using adobe reader & adobe acrobat I see a overlap or thickened region in the middle of the arrow. How do you make it one, continuous line?

[ghostanime2001]

any ideas?

Dumb question, but: Did you try another reader? or another zoomlevel? Or did you actually print the page and examined the example?

Sometimes pdf-viewers just do a bad job.

You can look here. I'm sure it's not a viewer issue, I have tried several PDF viewers.
