Hello All,

When I tried to write EXIF comments back to an image from a seperate file (i.e. a XML file that is created and stored all of EXIF comments when we load an image) by using L_SaveBitmap method, it seems that I have to use L_SetComment to go through whole tag index by a loop. Is it possible to generate a string stream or char array that contains all of comments, and write it to an image with L_SaveBitmap or other save methods just once?

Thanks,

Urs

You can load the markers from the file using L_LoadMarkers, then call L_SetMarkers which will make the current thread use those markers for all L_SaveXXX functions until L_SetMarkers is called again. Refer to the function L_LoadMarkers in the API help file for a small example.
