Flash Vector Drawing(aka faved) is a tool for flash developers to extract vector shapes from pictures. It uses native flash drawing(lineTo, curveTo, etc.) and allows to export the drawn picture into flash code(specially formatted or pure).
µSprite is a vector graphics editor for ActionScript 3 and haXe written in AS3. It generates AS3/haXe while it is being drawn and parses saved scripts so drawing can continue anytime. It implements multiple layers, masks, tween and path based animation.
