Extended Error Information
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

Remarks
The ImageServer server object provides the implementation of the image service, and supports IImageServer, IImageServer2, IImageServer3 interfaces. These interfaces are 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. These interfaces also support 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. IImageServer2 and IImageServer3 provides an additional method to scale the image into squared pixel size and export to a well-known format. IImageServer3 provides additional methods to access the catalog of an image service published from a mosaic definition, such as select catalog items based on a query, get the catalog items, metadata, and download the selected items.
