Vector Magic

可以將點陣圖 (Bitmap) 轉為向量圖 (Vector)，一般的常見的點陣圖都支援，輸出的話會輸出成EPS或SVG，對於影像處理時覺得解析度不夠大的圖，這倒是蠻方便的，不過應該還是以輸入簡單的圖形為主吧。

Vectorization (aka tracing) is the process of converting a pixel-based image into an image represented by geometric shapes such as lines, circles and curves.

Vector art is used because it allows you to scale an image without making it blurry or pixelated.
