I feel like I must be missing something: below is some "minimal sample" code which reproduces a "problem" I'm seeing in a more complicated situation: import matplotlib as MPL from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas from matplotlib.figure import Figure for DPI in range(100,201,25): fig = Figure(figsize=(12,9), dpi=DPI, frameon=False) canvas = FigureCanvas(fig) nx, ny = (N.uint16(12*DPI), N.uint16(9*DPI)) temp = N.indices((ny, nx), N.uint8) result = N.zeros_like(temp[0]) result[:ny/2,:] = temp[0,:ny/2,:] + temp[1,:ny/2,:] result[ny/2:,:] = temp[0,ny/2:,:]  temp[1,ny/2:,:] fig.figimage(result/N.float(N.max(result))) canvas.print_figure("test"+str(DPI)+"dpi.png") Attached are the results on my computer (see usage details below). Granted, I'm increasing the resolution each iteration, but I'm always placing the "cut" in the figure half way through  why does the cut keep creeping up 'til it disappears? Usage details: matplotlib version=? (I forget how to get that), numpy version = 1.0.4, Python version = 2.5.2, OS = Windows XPProSP3, 504 MB RAM w/ "Physical Address Extension" (whatever that means). DG PS: If the figures don't come through and for some reason my code doesn't work on your platform or doesn't reproduce the problem, email me and I'll email you the figures directly.
