New Post: Converting(any?) image to black and white

First off, very cool library, thank you for creating it. Also, my questions are probably more related to my lack of image understanding than the library but anyway.

I have a JPG file(which I hope uploading to photobucket did not change.

and I am trying to convert it to a pure B&W 1 bit image, using either dithering, thresholding, etc.

When I convert it to a TIFF and use GROUP 4 compression I do seem to be able to get the image to turn B&W and I've been able to successfully convert it to TIFF, open and view it in other application etc.

But I cannot seem to save it as a JPG(original format) that is 1bit B&W.

I've tried all sorts of crazy combinations of the following mutators/function calls:
.BlackThreshold()
.BitDepth(Channels.All, 1)
.Depth = 1

I've also tried a .Strip() before those calls based on some other responses I saw about certain profiles overriding things(not sure if I fully understand that part).

The only thing that seems to work is this:

                    this.imageData[page].QuantizeColorSpace = ColorSpace.GRAY;
                    this.imageData[page].QuantizeDither = true;
                    this.imageData[page].Quantize();

But it turns it gray, not B&W

I hope this doesn't come across at nit-picky, just curious on how to achieve what I am looking for if it is even possible.

Side question: is there any documentation on what the actual function calls do? Like an MSDN/API doc?
