The RasterCodecs object contains several static classes which can be used to obtain information about an image. The RasterCodecs.GetExtension() static method can be used to obtain the typical file system extension for the specified format. Here's our documentation on the method.
RasterCodecs.GetExtension(RasterImageFormat)

The command accepts as a parameter any of the values in the RasterImageFormat enumeration.
RasterImageFormat

The return value is a string representing the typical file extension, without the leading period. Note this code snippet:

Code:


string extension = RasterCodecs.GetExtension(RasterImageFormat.CcittGroup4);

The value of extension would be "tif".

Here's a code snippet which displays all available extensions to the console.

Code:


RasterImageFormat[] allFormats = (RasterImageFormat[])Enum.GetValues(typeof(RasterImageFormat));
foreach (RasterImageFormat format in allFormats)
    Console.WriteLine(
        "RasterImageFormat:\t{0}\tExtension:\t{1}",
        Enum.GetName(typeof(RasterImageFormat), format).PadRight(20),
        RasterCodecs.GetExtension(format)
    );
