Re: [Laszlo-dev] LzDrawView - converting cubic bezier to quadratic bezier

Thu, 05 Jan 2006 14:26:47 -0800

Hi DL,

We'd certainly like to see a full whatwg implementation eventually, but the team doesn't currently have plans to do specific further work. I doubt we would get back to this before the second half of the year.

If you'd like to contribute these functions, though, we'd be more than willing to help you with the logistics and integrate your code!

Thanks,

jim

it reads ..

"OpenLaszlo implements a subset of the whatwg drawing APIs. For a discussion of where OpenLaszlo differs from the full whatwg specification, please see the LZX Reference Manual."


LzDrawView is based on whatwg.org



quadraticCurveTo(cpx, cpy, x, y) is supported in openlaszlo

but are there plans to support the other methods in Path specification?

in particular,

  • bezierCurveTo(cp1x, cp1y, cp2x, cp2y, x, y)
  • arcTo(x1, y1, x2, y2, radius)

_______________

If not, can a "cubic bezier to quadratic bezier conversion class" be implemented in openlaszlo?

i.e. to convert cubic bezier  to quadratic bezier

as in  CubicCurve.as which is included with AnimationPackage ....


also see Path.as  AnimationPackage ..

_______________

Reason for interest .. I am trying to import third party SVG vector drawings which are in cubic bezier and quadratic bezier syntax ... then convert this syntax to LzDrawView syntax.
