Remarks

The ImageServer server object provides the implementation of the image service, and supports IImageServer interface. The IImageServer interface is used to query the service information, and fetch pixels. The pixels are returned in a byte array and arranged in a band interleaved by pixel format plus a NoData mask. The byte array can be optionally compressed using JPEG (plus transparency), and LZ77 compression.

 

This interface also supports exporting an image into a well-known format and returning it as MIME data, or a URL. The supported well-known image format includes JPEG (plus transparency mask), PNG, BMP, and TIFF.
