Syntax
C#
VB
Objective-C
C++
Java
public void CopyMetadataTo( 
   RasterImage image, 
   RasterMetadataFlags flags 
) 
Public Sub CopyMetadataTo( _ 
   ByVal image As RasterImage, _ 
   ByVal flags As RasterMetadataFlags _ 
)  
- (void)copyMetadataTo:(LTRasterImage *)image  
                 flags:(LTRasterMetadataFlags)flags 
public void copyMetadataTo( 
  RasterImage image,  
  int flags 
) 
public: 
void CopyMetadataTo(  
   RasterImage^ image, 
   RasterMetadataFlags 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.
