Image Export uses this callback message to return a count of all of the output pages produced during an export operation. This count reflects the number of pages created by Outside In's processing of the input document; which in some cases may differ slightly from the number of pages as seen in the document's original application. The page count is not necessarily the same as the number of output files produced. For example, exporting to TIFF images will result in the same page count regardless of whether a single multi-page file was created or multiple individual TIFF files were created.
This callback occurs during the execution of EXRunExport.
