10) Traceline
Traceline changes scanned or imported bitmap images to editable outlines (line art) that can be exported or pasted to other programs. This powerful app allows you to convert company logos, hand-drawn graphics, cartoons and photos to editable, scalable outlines. It can import an impressive number of raster formats. Use Traceline's intuitive editing tools to "tweak" your outlines for ideal results. You can quickly switch between the Object Editor, the Node Editor and Freehand Drawing. The program's vectorized output can be used in sign making, engraving, routing, animations, graphic design, and desktop publishing — or in any program that accepts .wmf, .emf, or Adobe Illustrator files. Price: USD $79.95

9) Vextractor
Vextractor is a tool for transforming raster images into vector formats by building centerlines and outlines. This vector tool could be used for vectorizing charts, maps, schemes and other similar images for entering into CAD and GIS systems. An application has the option to set up a reference for images, in other words, to assign real coordinates to certain raster points. Thus, you get vector data not only in the raster coordinates, but also in the real geographical coordinates or in the chart coordinates. Price: USD $99 (volume licensing available).

8) Silhouette (previously known as Artline)
Silhouette provides quick tracing and a number of tools for tweaking your vectorized image, but don't start requesting only bitmap files from your clients just yet. FreeSoft has made its name in the sign-making industry with its FreeSign program for creating the quick signs you see at many "signs-in-a-hurry" places. The machines that create those signs require vector images to complete the cuts, so it's easy to see how that could lead to a demand for a product like Silhouette. Silhouette is a plug in for Adobe Illustrator 8 and later to convert bitmap images to vectors images with unique correction tools. It instantly converts black and white or color bitmap images into vector designs ready for use. Price: USD $192 / EUR 149 (Lite), USD $386 / EUR 299 (Pro) and USD $321 / EUR 249 (plugin)

7) Freehand Autotrace for Beginners
The FreeHand Autotrace tool converts bitmap objects into vector paths. FreeHand can also autotrace other vector objects which may already be on the page. Before FreeHand 7, the Autotrace tool was useful for converting only the most basic scans into vector Bezier curve art. However, in FreeHand 7, the Autotrace tool got a completely make over into a more powerful tool.

6) Vector Eye - The easiest way to convert images to line art
Faster than a tracing hand, this powerful software is the raster to vector converter for Illustrator (Adobe), CorelDraw (Corel), Flash (Macromedia), WebDraw (Jasc), Sodipodi (freeware) and any vector-based software. Vector Eye instantly converts scanned black-and-white or color raster images (bmp, jpg, tiff, png) into editable vector files (.svg, .ps, .eps). Just scan any sketch or select an image (or a sequence) in an AVI movie. Make bitmap adjustments (scale, select zone, enhance, swap colors, rotate...) and Vector Eye automatically creates multiple SVG files corresponding to different settings. You can analyze and modify until you get the results you want (quality, weight, number of vectors). Price: USD/Eur $25/€19 (basic), $51/€39 (classic), $64/€49 (Pro)
