Implementing ImageCodecEndBand

Your image decompressor component is not required to implement the ImageCodecEndBand function. If it does, the base image decompressor calls the function when the decompression of a band is complete or is terminated by the Image Compression Manager. The call simply notifies your component that decompression is finished. After your component handles the call, it can perform any tasks that are necessary when decompression is finished, such as disposing of data structures that are no longer used, after receiving notification. Note that because the ImageCodecEndBand function can be called at interrupt time, your image decompressor component cannot use this function to dispose of data structures; this must occur after handling the function.
