How to extract odd and even pages into separate PDF documents?
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 “Add Page Range…” button to add page range definition to this output document. Specify desired page ranges in “Range of Pages” dialog (total number of pages in the document will be displayed in the dialog) and uncheck “Include odd pages from the document” checkbox. This will tell AutoSplit to output only even pages to this output document. Click “OK” button to add this page ranges to the output. Now repeat this procedure and create second document that only odd pages from the input document. Now you have created descriptions for two output documents: first one will contain only even pages and second one will contain odd pages. Select appropriate output document naming options and click “OK” to start splitting process.
