The .Strip command does not influence the value of a pixel. It removes metadata from an image file (http://www.imagemagick.org/script/command-line-options.php#strip).
You should be able to do the following (this is the equivalent of convert.exe photo_zps3b2313f9.jpg -threshold 25% blackwhite.jpg):
But this does not seem to work and creates a completely white image. I will have to investigate this for you to figure out what is happening.
If you are looking for documentation about what actual function calls do I would advise you to visit: http://www.imagemagick.org/Usage/ or check the command line options on this page: http://www.imagemagick.org/script/command-line-options.php. The names of the command line options are almost the same as the methods in the MagickImage class.
