The only problem is the resampling. Each pixel represents a value calculated at a point on a 318x301 grid, so in resampling I loose or distort some of the fine detail. I do not understand why the image need to be resampled when using a vector based backend. I understand this is necessary for a raster backend, but surely with a vector backend you can just scale the image keeping the 318x301 resolution. I know this is possible in Postscript at least as I've produced the desired output by amalgamating two files. See http://jimmacdonald.co.uk/matplotlib/image_CORRECT_ps_hacked.eps I looked at using pcolor instead, but the postscript files where too big (~20MB) due to the large number of tiles (this is how I used to do it in matlab).
