AGSTileInfo Class Reference

Description

The tiling scheme of a tiled layer.

This object represents the tiling scheme used by a cached map service. For example, ArcGIS Server cached map service, Bing Maps, etc. The tiling scheme contains information about how a map is broken up into tiles of images and how a client can use these tiles to display a map.

Property Documentation

compressionQuality

- (float) compressionQuality

readnonatomicassign

The compression quality of the tile images. The compression quality controls how much loss the image will be subjected to by the compression algorithm. The values of the pixels of an image compressed with a higher compression quality will be closer to those of the original image. The valid range of compression quality values is from 1 to 100.

DPI

- (NSInteger) DPI

readnonatomicassign

The Dots-Per-Inch (DPI) resolution of tiled images.
