How to extract pages contained between two bookmarks?
Open AutoSplit settings dialog by selecting “Plug-ins / Split Document…” from main menu. Set “Split Method” to “Use manually defined page ranges”. Now click on “Add Output Document” button and new output document will be added to output documents view. Click “Range From Bookmark…” button. “Select Bookmark…” dialog will pop up on screen. Select desired bookmark from the bookmark tree and click “OK”. AutoSplit will automatically add page range to the description of output document that belongs to this bookmark. Each bookmark defines a page range that starts at bookmarked page and ends on the page before next bookmarked page in the document. Select appropriate output document naming options and click “OK” to start splitting process.
