Reference_Syntax.before = “auto | contentArea | pageArea | pageBack | pageEven | pageFront | pageOdd”
The behaviors described below can be further refined by optionally specifying a destination page or content area using the beforeTarget (deprecated) property. The startNew property also modifies some of these behaviors:
auto (default)
The determination of a transition to a new page or content area is delegated to the processing application. No transition to a new page or content area is forced.
When duplexing, rendering transitions to the next available back surface, potentially causing an intervening page surface to print. If duplexing is not in effect, rendering transitions to a new page. Note that pageBack, unlike pageEven, is not affected by page numbering.
Rendering transitions to the next available even numbered page, potentially causing intervening numbered or unnumbered pages to print. This behavior does not require duplexing.
When duplexing, rendering transitions to the next available front surface, potentially causing an intervening page surface to be printed. If duplexing is not in effect, rendering will transition to a new page. Note that pageFront, unlike pageOdd, is not affected by page numbering.
Rendering transitions to the next available odd numbered page, potentially causing intervening numbered or unnumbered pages to print. This behavior does not require duplexing.
