Graphics, Figures & Tables ⇒ Line Thickness for Vector

[thomgraf]

Hello:

I want to have a bold vector within a picture environment.

I am using

Code: Select all

\linethickness{1mm}
\put(7,1.25){\vector(1,0){1}}

This, however, only increases the thickness of the actual vector line, not the thickness of the two lines that constitute the arrow head. The result is one thick line because the actual vector line itself is thicker than the arrow head whose two line thicknesses remains unchanged.

How can I create a bold vector? I could define three thick lines (not vectors) where one is the actual vector line, and the other two represent the arrow head, but that wouldn't be too elegant.

Thank you!

It's amazing that there are still some people who try to draw in the {picture} environment from vanilla LaTeX. If you want to stay with its syntax you should try some extending packages.

• curve2e
• pict2e

But there is no guaranty that these extensions solve the scaling problem for the arrow tip of your vector.

For easier drawing with a more sophisticated syntax there are corresponding graphics packages and third party tools.

• pgf/tikZ (Example Gallery)
• PSTricks (Example Gallery)
• MetaPost (Example Gallery)
• Asymptote (Example Gallery)
