convert bitmap to monochrome or black and white

[sdlangers]

hi,

i need to save a bitmap as a 2 color black and white bitmap using .net

if you load a bitmap in paintbrush, you can select save as monochrome and it saves it as a 2 color black and white image

Dim b As New Bitmap("test.bmp")

.. whats next?


how can i do this in .net code?

thanks!
