def WriteMarkers(self,fileName,pageNumber,markers):
fileName
A String that contains the file name.
pageNumber
1-based index of the page at which to write the marker.
markers
A collection of RasterMarkerMetadata objects that contains the marker data.
For Exif files, this metadata collection will contain all the Exif and GPS comments, stored in APP1. It will also contain the audio information stored in APP2.
Only JPEG and Exif JPEG files support writing markers.
