What is the Javascript for flattening all visible layers in a PDF?

If you are talking about OCGs, then unfortunately, there isn't a direct way to flatten the layers using Acrobat JavaScript. As far as I know, the menu items aren't even available. There are some tricks you can play, like importing the PDF page into a button image. But this is not a methology that is suitable for users on Reader. Basically there isn't a way. The best you can do is to set the "initState" and block further changes, so that the layer states are locked in.

Thanks Thom!

Yeah OCGs is what I am trying to control...

Bummer.... how would I perform the initState?

Maybe I can give that a try to see what it does...?


Thanks!

"initState" is a property of the OCG Object in Acrobat JavaScript. You can set this property and it is saved with the PDF. Basically you are just telling acrobat whether or not to turn the OCG on when the file is opened.

oh, I see... thanks Thom,

It is possible to assign an initState for an individual layer (OCG) based on the clicking of a Button?

What is the actual script for setting the initState for an OCG, for example a layer titled "sample" to in a display state upon initial view?


Sorry so many questions... : )


Kevin

Is this correct?

sample.initState = true;


is there any other syntax needed to make this a functional Javascript?

I wrote an article on this topic:

I'll read through the tutorial... will let you know if any questions come up.

Thank you for your help Thom. I really appreciate it!
