Is It Possible to Bates-stamp (or add header/footer) USING A SCRIPT?

Question

I need to Bates-stamp (or add a header/footer) to >1000 docments. The Bates-stamp (or header/footer) needs to contain ONLY the first four characters of the filename. Is there a way to do this using only the tools that are part of Acrobat X Professoinal?
If not possible using the toold of Acrobat X Pro, is anyone aware of a third-party plugin that would do this?

Answer 1

You can use a Javascript function to place something onto one or more files as a watermark, which visually is the same as a header/footer even though internally it won't be tagged as such. For example:
addWatermarkFromText({
  cText: this.documentFileName.substring(0,4),
  nTextAlign: app.constants.align.right,
  nHorizAlign: app.constants.align.right,
  nVertAlign: app.constants.align.top,
  nHorizValue: -72, nVertValue: -72
paste it into the JS console to test it (Ctrl-J or CMD-J), to run it against a bunch of files create a new Action and use the "run a Javascript" step. See the SDK documentation for the parameters you can set on the function.
There's no script access to Bates numbering or the H&F creation dialog.
