                 flags:(LTRasterMetadataFlags)flags

public void copyMetadataTo( 
   RasterImage image, 
   int flags 
);

public: 
void CopyMetadataTo(  
   RasterImage^ image, 
   RasterMetadataFlags flags 
)

def CopyMetadataTo(self,image,flags):

Parameters

image
Destination image

flags
Type of metadata to copy

Remarks

This methods copies the metadata found in the Tags, Comments and/or Markers collections of this RasterImage to image.

Before the copy operation, this method will clear any metadata already found in image.
