could you give me your opinion on the clipping issue pointed here:

> *Besides, I found an important bug in pisces Stroker / Dasher: it does
> not use the clip region given to PiscesRenderingEngine.**
> getAATileGenerator(clip).
> In Aspro2, I can zoom on jFreeChart plots a lot and it draws shapes
> (rectangle or lines with dashed lines) then the dasher emits segments out
> of the visible area (millions in case of a important zoom) and the
> application hangs a for while (5s to minutes).* *
> *
> *I would like to determine the shape part (line or any complex shape)
> that is inside the clip and avoid useless segments (Stroker / Dasher).
> Does somebody have any idea ?
> or know java2d.pisces code enough to help me ?
