In ArcCatalog if you open the propreties of a RasterDataset you can edit the value of the NoData value. On the Edit form, there's a button that says Compute (see attached). I'm guessing this is based on the raster's pixel type & depth. Is there a method on one of the many raster interfaces that can determine this value for you or do I need to write my own, e.g. using IRasterInfo::PixelType and switch statement?
Sorry, I should be been more clear in my original post. I'm writing out a Raster Dataset & need to determine the appropriate value to pass in to IRasterProps::NoDataValue after using CreateRasterDataset from a RasterWorkspace, hence my line of thinking of using a combination of the pixel type and bit depth.
