VectorMagic vectorizes your bitmaps

Sometimes, you need to change your images from a bitmap (JPEG, TIFF, BMP or raw file) to a vector file that can be stretched and grown seamlessly. This is useful when the image is more or less a drawing (not a photo) with clear drawn borders (a logo, a signature, a technical drawing, etc.)

Here comes VectorMagic that can do a pretty good job of this (even if some details will probably be lost in the process).
