mosaicRule

The image service uses a mosaic rule to mosaick multiple rasters on the fly. The mosaic rule parameter is used by many image service operations, for example, export image and identify operations.

Properties

Property	Details
ascending	Indicate whether to use ascending or descending order.
fids	A list that defines a subset of rasters used in the mosaic, be aware that the rasters may not be visible at all scales.
itemRenderingRule	The rendering rule applies on items before mosaicking.
lockRasterIds	Lock a few rasters in the image service. Used together with `esriMosaicLockRaster`.
mosaicMethod	A string value that determines how the selected rasters are ordered. Must be one of the following values: `esriMosaicNone` `esriMosaicCenter` `esriMosaicNadir` `esriMosaicViewpoint` `esriMosaicAttribute` `esriMosaicLockRaster` `esriMosaicNorthwest` `esriMosaicSeamline`
mosaicOperation	Use the mosaic operation to resolve overlap pixel values: from first or last raster, use the min, max or mean of the pixel values, or blend them. If property is present, must be one of the following values: `MT_FIRST` `MT_LAST` `MT_MIN` `MT_MAX` `MT_MEAN` `MT_BLEND` `MT_SUM`
multidimensionalDefinition	Definition of multidimentional variables.
sortField	The field name used together with `esriMosaicAttribute` method.
sortValue	The base sort value used together with `esriMosaicAttribute` method and `sortField` parameter. Must be one of the following values: `Number` `String` `Null`
viewpoint	Use a view point along with `esriMosaicViewpoint`.
where	Deprecated. Use `layerDefinition.definitionExpression` instead.
