RE: [Matplotlib-users] figimage filling entire image

[Perry G. <pe...@st...>]

If you want an image to spatially scale with the plot window, use 
implot instead of figimage. Figimage does not resample images spatially
but rather displays them pixel for pixel (that's what distinguishes 
the two functions)
