%description
Potrace is a utility for tracing a bitmap, which means, transforming a bitmap 
into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP
format), and the default output is an encapsulated PostScript file (EPS).
A typical use is to create EPS files from scanned data, such as company or
university logos, handwritten notes, etc. The resulting image is not "jaggy"
like a bitmap, but smooth. It can then be rendered at any resolution.

Potrace can currently produce the following output formats: EPS, PostScript,
PDF, SVG (scalable vector graphics), Xfig, Gimppath, and PGM (for easy
antialiasing). Additional backends might be added in the future.

Mkbitmap is a program distributed with Potrace which can be used to pre-process
the input for better tracing behavior on greyscale and color images.

%description -l ja
potrace はビットマップ画像をトレースするツールです．ビットマップ画像を
滑らかで拡大縮小できる画像に変換します．社章、校章、手書き図のスキャン
画像から滑らかなEPSを得るには，例えば，
convert hoge.bmp pbm:- | mkbitmap -s 2 | potrace -a -1 -C "#202020" > hoge.eps
とします．入力形式がPBMであることに注意してください．
