Parameters

stream
A ILeadStream containing the output file data.

pageNumber
1-based index of the page at which to write the marker.

marker

Remarks

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.

When you add or remove tags, the tags array at the end of the file is re-written. When you modify existing tags, the new tag value is added to the file and the IFD is modified as necessary. In all of these cases, there is no image recompression.
