Sets the metadata markers to be used in the current thread.


#include "ltwrappr.h"

virtual L_INT LMarker::SetAsGlobalMarkers(uFlags)


L_UINT uFlags

Reserved for future use. Pass 0.


Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.


All save operations performed in this thread will use these markers until LMarker::SetAsGlobalMarkers is called again.

A copy of these markers will be used, so you can delete the marker object when LMarker::SetAsGlobalMarkers returns.

Comments set with LFileSettings::SetComment will take precedence over any comments contained in the markers.

Tags set with LFileSettings::SetTag will take precedence over any user-defined tags contained in the markers.

If the LFile::SaveXXX function is instructed to save a stamp, the stamp will be regenerated from the bitmap and will override whatever Exif stamp is present in the markers.

Required DLLs and Libraries


Win32, x64.
