Imposition Wizard can be controlled using AppleScript. You may open projects, set source and target PDF files and run the imposition process. This is enough for most automation tasks. See the script example below that imposes PDF file and open the result in Preview application.
set project to "/path/to/project.impproj" set src to "/path/to/source.pdf" set dst to "/path/to/target.pdf" tell application "Imposition Wizard" activate open project tell first document set source to src impose in dst close saving no end tell end tell tell application "Preview" open dst end tell
Please note that in Tiger you should use the following synthax for open command, but keep the original synthax for source and destination paths:
set project to "Macintosh HD:path:to:project.impproj" set src to "/path/to/source.pdf" set dst to "/path/to/target.pdf"
Since version 1.6 there is no property named target in the document and method impose is extended with target file parameter. See the new proper synthax in the sample above.
