Summary

Copies the metadata (tags, comments, and markers) to the given image.

Syntax

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.
