public byte[] getImage(IGeoImageDescription pImageDescription)
throws IOException,
AutomationException
Gets the image data in byte array from the image service using the given GeoImageDescription.
Gets the image data for a given image description. The returned image data contains first pixel values and then followed by NoData (transparency) bit mask, i.e. <pixels><mask>. The pixel values are organized in a band interleaved by pixel format, as the following:
v[0,0,0], v[1,0,0], v[2,0,0],…, v[nBands-1,0,0],
v[0,0,1], v[1,0,1], v[2,0,1],…, v[nBands-1, 0,1], …,
v[0,nRows-1,nCols-1], …, v[nBands-1,nRows-1,nCols-1]
where nCols, nRows, and nBands are the number of columns, number of rows, and number of bands of the returned image, and v[b,I,j] is a pixel value at band number b, row number I, and column number j. The size in terms of number of bytes of a pixel value depends on pixel type. The following table shows the pixel type to pixel size mapping:
PT_U1 1
PT_U2 1
PT_U4 1
PT_UCHAR 1
PT_CHAR 1
PT_USHORT 2
PT_SHORT 2
PT_ULONG 4
PT_LONG 4
PT_FLOAT 4
PT_DOUBLE 8
The location of the pixel at band b, row I, and column j can be calculated using the following formula:
location = ((i*nCols+j)*nBands+b)*pixelsize (in bytes)
The pixel data are always in Intel (Little Endian) byte order. For pixel types of more than 1 byte, byte swapping may be needed.
The NoData mask is a bit mask, one bit per pixels of all bands, with no padding to the byte boundary for a row. Value 1 indicates the pixel is valid, and 0 indicates NoData. The mask value for a pixel at row I and column j can be calculated as the following:
Bit[] = {0x80, 0x40, 0x20, 0x10, 0x08, 0x04, 0x02, 0x01}
l = i*nCols+j
m[l/8] & Bit[l%8]
The NoData immediately follows pixel data. The size of NoData mask in bytes is (nCols*nRows+7)/8.
The NoData mask is optional. If the total size of the returned image data greater than the pixel data size i.e. nRows*nCols*nBands*pixelsize, then the NoData mask is present.
If LZ77 compressed, the returned image data must be uncompressed (zlib). The uncompressed image data follow the same format as above.
If JPEG compressed, the returned image data are organized as JPEG data stream followed NoData mask, and followed by the size of the JPEG stream, i.e. <JPEG><mask><size>. The NoData mask is the same format as above, but is LZ77 compressed. The JPEG data stream size <size> is a 4-byte integer in Intel byte order.

AutomationException - If the ArcObject component throws an exception.IGeoImageDescription
public IImageResult exportImage(IGeoImageDescription pImageDescription,
IImageType pImageType)
throws IOException,
AutomationException
Exports image data from the image server using the GeoImageDescription and ImagType.
The supported formats, defined using the ImageType parameter, include JPEG, PNG, BMP, and TIFF. The JPEG format is the same as the JPEG compressed image returned from the GetImage method. Image content can be returned as a URL or as a MIME data stream.
If the size of the image in terms of number of columns and rows exceeds the limit defined in the image service configuration, this method will return an error.
If the pixel type defined in ImageDescription is different from the pixel type of
the image service, the pixel values will be converted according to the specified
pixel type if possible. Otherwise, an error will be returned at 9.3.
New at 9.4, if the image service pixel type cannot be converted to the requested pixel type, a default raster renderer will be applied. A proper default renderer is created using the same rule as when a raster dataset of the same properties, e.g. number of band, pixel type, and etc is added to map.

public IMapImage exportMapImage(IGeoImageDescription pImageDescription,
IImageType pImageType)
throws IOException,
AutomationException
Exports an image to a supported format including JPEG, PNG, BMP, and TIFF, scales the image into a square pixel size, and returns both the image data and the adjusted image extent for a given image description. Comparing to ExportImage, ExportMapImage exports a MapImage which contains information defined in ImageResult plus image extent and map scale.
If the size of the image exceeds the limit defined in the image service
configuration, this method will return an error.
If the pixel type defined in ImageDescription is different from the pixel type of
the image service, the pixel values will be converted according to the specified
pixel type if possible. Otherwise, an error will be returned at 9.3.
New at 10, if the image service pixel type cannot be converted to the requested pixel type, a default raster renderer will be applied. A proper default renderer is created using the same rule as when a raster dataset of the same properties, e.g. number of band, pixel type, and etc is added to map.

throws IOException,
AutomationException
If an ImageQueryFilter with a pixel size is specified, the query will include the selection based on the image service level of details. An image service uses a minimum and maximum pixel size range to define when an individual image will be selected as a part of a mosaic. If a pixel size is given, only these images whose pixel size range contains the given pixel size are selected.

public IImageServerDownloadResults download(IFIDSet pFIDs,
IGeometry pGeometry,
String format)
throws IOException,
AutomationException
The Download method return an ImageServerDownloadResults which contains multiple ImageServerDownloadResult objects, and each one of them contain a downloadable file and its size in bytes.
The number of items that can be downloaded is defined in the image service
configuration. One item might be corresponding to multiple files. For example a raster of a pan-sharpened image service consists of a single band raster dataset and a multiple band raster dataset, where each dataset might consist of multiple files such as an image file, a world file, and a pyramid file.The returned downloadable files can be URLs (e.g. http:// or ftp://) that are directly downloadable from a remote server. They can also be files that are known only to the image service. In this case, GetFile() should be used to prepare the file for download and get a public URL.
Downloading formats of folder structure, for example ESRI GRID, is not supported.

throws IOException,
AutomationException
Identify return an ImageServerIdentifyResult which contains a single pixel value of the current visible raster at the centroid of the specified location. If there are multiple rasters overlapping the location, the visibility of a raster is determined by the order of the rasters defined in the mosaic rule. It also contains a set of catalog items in a RecordSet that overlap the given geometry. The catalog items are ordered based in the mosaic rule. A list of catalog item visibilities give the percentage contribution of the item to overall mosaic.
