Applying Live effects (offset path) in Illustrator using AS

Hi anyone,  one more question

<LiveEffect name='Adobe Offset Path'><Dict data='R mlim 4 R ofst 20 I jntp 2 '/></LiveEffect>"

Is there a way that we can make the (ofst 20) as a string…?

like offsetvalueinput

Thanks again  

Wow...   it works!    This is exactly what I need

Thank you very much Silly

Your answer is actually one of the most arcane Illustrator Scripting subjects, and as luck would have it, the answer is in fact the very first example provided by CarlosCanto which let us all in on the secret, and it's here: Re: PageItem.applyEffect(LiveEffectXML)

The challenge is in two parts, first you have to obtain and prepare your live effect xml syntax for the Offset Path effect and then you have to apply it with some code.

Some more AI scripting 'rules' for these live effects:

• applying a new effect will add it to the art, compounding with previous effects
• to reduce the effects, is possible by applying a pre-prepared 'default/no-style' graphic style or using an Action or app.executeMenuCommand(...) to reduce to basic appearance or clear appearance.
• The effect is live, to turn it into real paths will take another action or menu command 'expand appearance'

Also one other thread which also has other effect examples is here:

Apply Live Effect: Inner Glow with color

Please enjoy this amazing Illustrator scripting feature, it's been hidden for years and is only available to us through the good graces of the powers that be.

* As for AS, just use a do javascript command - I'm not sure about the AS vocabulary for the liveEffect syntax myself and usually take the lazy way out by having my AS run my JSXs.
