Saving TIFF tags in C#

[BuncyTheFrog]

Working in C# in Visual Studio 2005

So I know how to edit TIFF tags (get a propertyItem object, edit its details, and stick it into a bitmap), but saving them is presenting itself as a problem.

After I'm done drawing on the bitmap, I convert it to 1bbp, then stick the propertyItems onto the bitmap. I've checked, and I can see each of the propertyItems I've put into the bitmap. I then save the file using the TIFF encoder and CCITT4 compression.
When I actually look at the tags, all that's there are the default tags generated by the TIFF encoder.

A little snippit of my code:

System.Drawing.Imaging.Encoder comp = System.Drawing.Imaging.Encoder.Compression;
            EncoderParameters parms = new EncoderParameters(1);
            parms.Param[0] = new EncoderParameter(comp,(long)EncoderValue.CompressionCCITT4);
            ImageCodecInfo info = GetEncoder(ImageFormat.Tiff);

            PropertyItem fillorder = resourceBitmap.GetPropertyItem(256);
            fillorder.Id = 266;
            fillorder.Len = 1;
            fillorder.Type = 4;
            fillorder.Value = new byte[1] { 1 };
            PropertyItem imageDescription = resourceBitmap.GetPropertyItem(256);
            imageDescription.Id = 270;
            imageDescription.Value = new byte[0] { };
            imageDescription.Len = 0;
            imageDescription.Type = 4;
            PropertyItem orientation = resourceBitmap.GetPropertyItem(256);
            orientation.Id = 274;
            orientation.Value = new byte[1] { 1 };
            orientation.Len = 1;
            orientation.Type = 4;
            PropertyItem t6option = resourceBitmap.GetPropertyItem(256);
            t6option.Id = 293;
            t6option.Value = new byte[1] { 0 };
            t6option.Len = 1;
            t6option.Type = 4;

The bitmap is drawn on and converted to 1bpp (the name is workingFront), then the items are applied and saved:

workingFront.SetPropertyItem(fillorder);
                    workingFront.SetPropertyItem(imageDescription);
                    workingFront.SetPropertyItem(orientation);
                    workingFront.SetPropertyItem(t6option);

                    workingFront.Save(outFile, info, parms);

Now, is it that I'm not using an encoder parameter that I should be? Perhaps the method isn't even how you're supposed to be able to get TIFF tags into a TIFF image? I also think that perhaps I haven't formatted the propertyItems correctly. I'm not sure, there aren't very many examples out there about this stuff at all.

Hmm, nevermind. It looks like I was formatting my propertyitem objects incorrectly (I looked at the property items in the file I was stripping them off of, and noticed that I was doing it a lot differently than what was in that object).
