[javascript] Limit on size of global object? SOLVED

[Mathew]

Looking at the js API for global object methods there's a vague note under setPersistent() "For Acrobat 6.0 or later, there is a 2-4 KB limit on the size of this file. Any data added to the string after this limit is dropped."

Is this enforced in PDF-XChange or is there some other limit?

On my computer GlobData is already over 2k, and I'm wondering if I can use it to store some data for javascript tools that would definitely put it over 4k (without clobbering data from other tools) - or is there another way to store data for javascript that can be accessed between documents? There's util.readFileInterStream() but I don't see any equivalent writeStreamIntoFile()...

Hi Mathew,
The Editor does not explicitly limit GlobData file size but limits the number of persistent properties by 65536.
As of an alternative to persistent global properties, you can consider Doc.createDataObject, Doc.exportDataObject, Doc.importDataObject and related API.

Thank you Roman. I'll do some noodling with those, but it's good to know that there's no arbitrary limit on the persistent global properties themselves.

The doc.exportDataObject() function looks like it's been made to not work for a script's storage. Seems I'm bumping up against a very intentional effort to not allow scripts to write to a user's hard drive:

Beginning with Acrobat 6.0, if the parameter cDIPath is non-null, a NotAllowedError (see Error object) exception is thrown and the method fails.

I'm thinking one could use use an empty pdf for storage as app.openDoc(), doc.saveAs() allows writing to a safe path; maybe that's my route.

Thanks again.
