Can not encode with RSS barcodes.

[Yujin]

I am creating RSS-14 and RSS_Extended bar codes in C # using Zxing.

I compiled it with the code below and found an error on line 3 below
: System.ArgumentException: 'No encoder available for format RSS_EXPANDED'

var writer = new BarcodeWriter
{
Format = BarcodeFormat.RSS_EXPANDED,
Options = new ZXing.Common.EncodingOptions
{
PureBarcode = true,
Height = rh,
Width = 0,
Margin = 1
}
};
var image = writer.Write("0108801234560030");
Bitmap bitmap = new Bitmap(image);
e.Graphics.DrawImage(bitmap, rx, ry, rw, rh);

Like FNC1 on GS1-128, is there a special format for creating RSS_EXTENDED bar codes? Or is it just a number? (If you know the format of RSS-14, please let me know)
Also tell me why System.ArgumentException appeared.

No one ever wrote an encoder for RSS Expanded.
That's what the exception says.
Or in other words you can't encode RSS Expanded with zxing.
