I just finished the first cut at the quadratic arc decorators for the Freehand Drawing Library. Previously, only solid arcs could be drawn. The example below shows dashed- and dotted-line decoration applied to arrowed arcs.
The decorators all share a fast, on-the-fly arc-length parameterization utility. I still have a few tweaks to make to one of the decorators before full production release, but the new library is going out to all beta users this morning.
Based on feedback, I’m going to add one more stroke (Polygonal) and two spline-based drawing engines to the full release. Because of this new addition, I’m seeking a couple more beta users. If your drawing requirements could benefit from a variety of splines, including splines that auto-convert to shapes (i.e. lines and quads) for creating dynamic outlines/fills, please e-mail me for more information on entering the beta program.
The beta includes full source code and there is a small, 3-figure license fee. All beta users get FREE upgrades for life. Email is theAlgorithmist [at] gmail [dot] com. Thanks!
