Metapostは比較的簡単にeps画像を作ることができる．

主な用途はtexに使うeps画像の作成だと思われる．

Metapostを少しつかってみたので，そのときのメモ．

とりあえず，今回つくった画像．

f🆔jeneshicc:20100103220132p:image 

prologues:=3;
beginfig();
h=30;
w=100;
r=70;
d=5;
draw (, h)--(2w, h);
draw (w, )--(w, h+w);
dotlabel.rt(btex ${rm i}c$ etex, (w, h+40));
pickup pencircle scaled 2pt;
draw (w-r, h)--(w+r, h)..(w, h+r)..cycle;
draw (w+h, h+0.7d)--(w+h+d,h)--(w+h, h-0.7d);
endfig;
end.

まず，tex環境について．

  • texlive 2008
  • ptexlive 2008

がインストール済み．

labelにtexを使うときはtexlive（pでない，日本語化されていなほう）でないと

うまくいかないみたい（理由は分からない）．

（理解できない）エラーメッセージとログは最後にのせる．

prologues:=3; と設定すると，数式のフォントがいつものtexになった．

pickup pencircle scaled 2pt; で線の太さを変更している．

The two files given above are one of your source files
and an auxiliary file I need to read to find out what your
btex..etex blocks mean. If you don't know why I had trouble,
try running it manually through MPto -tex, TeX, and DVItoMP.
