Do you have a file and you are not sure what type it is? This article explains how you can get RasterMaster to identify it for you. RasterMaster can recognize and process a wide variety of file formats. You do not have to tell RasterMaster what the format is. Unlike Windows which relies on someone naming the file correctly, RasterMaster uses the data in the file to identify the file type, even if the file has a misleading filename extension.
You can use the IMGLOW_get_filetype() method to identify an unknown file format. This method returns a file type number that corresponds to a file type defined in the RasterMaster library. Please see the list of file type constants below.
