B4JLibraryDrawing

jCanvasExt Extends Canvas methods

This library, with the Class source code, extends the Canvas functionalities. Some time ago I was playing with B4J Canvas with methods not exposed directly to B4J. There was a question in the forum for a routine to draw rectangles with round corners. So, I think it may be useful for others.

Handy Median Filter With Side Salads

I am making a Shortt Free Pendulum clock and record the time error. When making changes to the tuning of the pendulum you must stop it from moving. This creates artifacts in the time data which are a nuisance when plotting trends. To get rid of these artifacts I made a median filter class with a variable window. I use a list as the window as this makes sorting a breeze. However a median filter is a blunt instrument so I added a couple of side salads.
