Need conversion to pure black and white

[qwert]

Does anyone know of a script or utility that can convert a .BMP to a 2-color result (i.e., black and white). I've searched several times, here and on the 'net, but can't come up with any simple solution. Output/input could be either .BMP or .PNG.

Thanks in advance for any help.

Thanks for responding. I've viewed about 20 related posts and can't see anything to use. What I have is a bitmap file on disk and need a small conversion utility that can be run from a command line. Something like:

convert.exe bitmap.bmp result.bmp

I've downloaded a couple of "packages" that can do it -- but they're each over 4 megabytes. I need something 1/10 that size -- hopefully, less.

$pic = LoadExtImage("your_bitmap.bmp")
$array1 = InitExtFX($pic)
Black_White($hDC, 0, 0, $array1, 127, 1)
