How to change mosaic properties on an image service layer


Summary
Image services support different mosaic rules. Mosaic rules define the order and overlap handling of multiple images. This topic shows how to programmatically change the mosaic rule for an image service layer.

Changing mosaic properties on an image service layer

Do the following steps to set mosaic properties on an image service layer:
  1. Open the image service layer.
  2. Get the mosaic rule from the layer.
  3. Change the mosaic method, operator, and/or other properties.
  4. Save the image service layer.

    See the following code example:
[C#]
static void SetMosaicPropertiesOnISLayer(string layerPath)
{
    //Open the layer.
    ILayerFile islayerFile=new LayerFileClass();
    islayerFile.Open(layerPath);

    //Get the mosaic rule.
    IImageServerLayer3 isLayer=islayerFile.Layer as IImageServerLayer3;
    IMosaicRule mRule=isLayer.MosaicRule;

    //Modify the mosaic method, operator, and so on.
    mRule.MosaicMethod=esriMosaicMethod.esriMosaicNorthwest;
    mRule.MosaicOperatorType=rstMosaicOperatorType.MT_FIRST;

    //Save the layer.
    islayerFile.Save();
}
[VB.NET]
Private Shared Sub SetMosaicPropertiesOnISLayer(ByVal layerPath As String)
'Open the layer.
Dim islayerFile As ILayerFile=New LayerFileClass()
islayerFile.Open(layerPath)

'Get the mosaic rule.
Dim isLayer As IImageServerLayer3=TryCast(islayerFile.Layer, IImageServerLayer3)
Dim mRule As IMosaicRule=isLayer.MosaicRule

'Modify the mosaic method, operator, and so on.
mRule.MosaicMethod=esriMosaicMethod.esriMosaicNorthwest
mRule.MosaicOperatorType=rstMosaicOperatorType.MT_FIRST

'Save the layer.
islayerFile.Save()
End Sub
