AGSMosaicRule Class Reference

Description

A rule determining how a requested image should participate in the mosaic.

https://desktop.arcgis.com/en/arcmap/10.6/manage-data/raster-and-images/understanding-the-mosaicking-rules-for-a-mosaic-dataset.htm An image service uses a mosaic rule to mosaic multiple rasters on-the-fly. A mosaic rule parameter is used by many image service operations, such as export image and identify operations.

lockRasterIDs

- (NSArray<NSNumber *>*) lockRasterIDs

readwritenonatomiccopy

An array of raster IDs for image service rasters forced to be visible at all scales.

Used with AGSMosaicMethodLockRaster. Cannot be greater than the maximum mosaic image count of the service.

Since

mosaicMethod

- (AGSMosaicMethod) mosaicMethod

readwritenonatomicassign

Specifies the type of AGSMosaicMethod used for sorting rasters in a mosaic dataset.

The default value is the value used when the mosaic data was created, if unavailable, the default value is AGSMosaicMethodNone.

Since

mosaicOperation

- (AGSMosaicOperation) mosaicOperation

readwritenonatomicassign

Specifies the AGSMosaicOperation used to resolve overlapped pixel values from various rasters in a mosaic dataset.

The default value is the value used when the mosaic data was created, if unavailable, the default value is AGSMosaicOperationFirst.

Since
