Retain "pixel"ation in coastlines (map)

Hello all,

Is there any way to remove smoothing in Matlab's map coastlines? I would like to retain the "pixel"ation of the coastlines if possible. Below is the current map that I have.

figure('Color','white')
latlim = [-90  90];
lonlim = [  0 360];
gratsize = 1 + [diff(latlim), diff(wrapTo360(lonlim))]/6;
[lat, lon] = meshgrat(latlim, lonlim, gratsize);
ax= worldmap ('world')
setm(ax,'mlabelparallel',-90)
coast = load('coast');
geoshow(coast.lat, coast.long, 'Color', 'black')
contourfm(latlim,lonlim,finalmap')

Thank you for your time and input.

If you are using R2014b or later, try experimenting with the new GraphicsSmoothing control; see http://www.mathworks.com/help/matlab/examples/using-graphics-smoothing.html
