Thanks for the responses so far, everyone. Luis you are indeed a good
guesser! I'm using wxPython/matplotlib and would like to size my
matplotlib data figure so that it assumes a 1:1 ratio on the screen
when embedded in a wxPython form. I'm playing with a 2D array with 320
rows and 177 columns and therefore would like to display the figure
with a size of 320x177 pixels. The problem is that the call to
instantiate the figure takes size parameters of inches and dpi! For
example:

matplotlib.figure.Figure((5,4), 75)

is a figure with width of 5 inches, height of 4 inches, and dpi of 75.
Thanks to Luis' comment I googled around and found that wxPython has
the following functions:

wx.GetDisplaySize()    # Get dimensions in pixels.
wx.GetDisplaySizeMM()  # Get dimensions in millimeters.

It's a little klunky to have a function that takes inches an an
argument and another that produces millimeters when querying the
display, no? Unless someone has a better idea I suppose I'll have to
convert between the two to display at 1:1.

SInce I want my matplotlib.figure.Figure() to assume the exact pixel
dimensions of the 2D array,
