   RasterGetSetOverlayAttributesFlags flags
) 

Parameters

index

The zero-based index of the overlay for which the attributes are being set.

attributes

An RasterOverlayAttributes object containing the overlay attributes to set.

flags

Flags that determine which attributes to set.

This method can be used to set some or all the overlay attributes. Before calling this method, initialize the attributes object members with all the attributes to be set or changed.

You do not need to initialize the object variables that you are not setting or changing. For example, if RasterGetSetOverlayAttributesFlags.Origin is not set in flags, you do not need to initialize RasterOverlayAttributes.Origin member of attributes.

There are several attributes in flags and you cannot change only one flag. If you want to change only one flag, you will first have to get all the flags and change only the flag you want. See the example for more information.

For more information, refer to Overlay Overview.
