Making a rounded rect with arc
Feb 5th, 2009, 5:09pm  
I can't seem to make a rounded rectangle using five rectangles and four arcs without the seams showing through.  Please advise.  See the source and application at:

I see no gap. I see the strokes, but I suppose they are intentional.

I actually mean that I want to get rid of the overlap of the sections.  I've purposely used a fill with an alpha value to reveal the seams, which I want to eliminate.

All the section drawing is in RoundedRect.updateTransDimensions().  

I suspect the problem is because I'm using floats to compute the width and position of the arcs and rectangles, and the method used to convert the floats to ints is handled differently by processing's rect() method than the arc() method.  

How can I gaurantee that the arc is adjacent but not overlapping it's neighboring rect?  

Shouldn't arc( 10, 10, 20, 20, PI, PI + HALF_PI ) line up flush with rect( 10, 0, 40, 10 )?
