WinTopo is a computer software application for converting a raster image into a vector drawing.
I would like to Introduce www.Fatpaint.com a free, full featured, online graphic design software for doing layered painting, vector drawing, photo editing and page layout.
Illustrator introduced the uses of Bezier curves which allowed the user to be incredibly detailed in their vector drawings.
Also included with 4.0 is the Canvas class, which allows vector drawing.
The platform integrates text, video, handwriting, and vector drawing.
Users also use the drag-drop manipulation and recursive containment of pictures inside vector drawings to create variety of documents.
The online editor has a paint panel to create vector drawing and it can also be used to mimic handwriting.
Fatpaint integrates desktop publishing features with brush painting, vector drawing and custom printed products in a single Flash application.
The vector drawings can also be cropped, resized, skewed, distorted and rotated in 2D and 3D.
It does, however, include general Flash creation features such as vector drawing, motion tweens, and symbol editing.
