open, crop & Optimize PDF

Hi All,

Basically am from Indesign Java Scripting. But, very new to Adobe Acrobat Scripting.

Could you please help where to write the Acrobat Scripting. (in Indesign, ExtendToolKit support for writing, Debug etc..)

Request:

1. Open the PDF (i.e Desktop)

2. Crop the PDF as per Trim Size (multiple Pages)

3. Optimize PDF

4. Which toolkit is support to run the script.

Note: Using Mac

Thanks in Advance
