You can pass an "interpolation" parameter to imshow, or set a default in
"image.interpolation" in your matplotlibrc. From the imshow docstring:
* interpolation is one of:
'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36',
'hanning', 'hamming', 'hermite', 'kaiser', 'quadric',
'catrom', 'gaussian', 'bessel', 'mitchell', 'sinc',
'lanczos', 'blackman'
if interpolation is None, default to rc
image.interpolation. See also th the filternorm and
filterrad parameters
'nearest' is the one you want if you want to see sharp square pixels.

I'm not sure I understand the question. You mean to draw a line using
large pixels, rather than as a vector? I don't think there's an easy
way on that one -- but maybe someone else here can think of a creative
way to do it.
