function pdf_to_imagefield_nodeapi in PDF to ImageField 6.2

hook_nodeapi

When saving a node, see if it's got a PDF that needs converting. Pass processing to individual op handlers, D7-style

Sometimes we do the process immediately (single page) Sometimes we start a batch early (re-save an existing node) Sometimes we have to wait till after (save new node) and start a batch then.

• this might be reduced to two cases, but not sure..

      // Single operations happen at presave,
      // because then we can let filefield do the saving.

      break;
    case 'insert':

      // Batch operations happen at postsave, because we need to have a nid.
      // Batch ops trigger their own save (which by then is an update)
      // Beware of cycles - don't set a batch in update, or it will loop.
      return pdf_to_imagefield_node_insert($node);
      break;
