Aloha, I'd like to increase the resolution of the rasterized export of some plot. The ImageResolution option seems to do just that. So I try: In[1]:= ripples = Plot3D[1/y Cos[1/x], {x, -1, 1}, {y, -1, 1}]; In[2]:= Export["ripples-72.png", ripples, ImageResolution -> 72] Out[2]= "ripples-72.png" In[3]:= Export["ripples-300.png", ripples, ImageResolution -> 300] Out[3]= "ripples-300.png" This works pretty well, except that the image created with ImageResolution -> 300 has rather big empty borders, whereas the image created with ImageResolution -> 72 (or no ImageResolution option whatsoever) has a nice tight bounding box, i.e. no unnecessary borders. Does anyone know why this happens? Is there a way to avoid it? This is with Mathematica 6.0.1 on openSUSE 10.2 on an x86_64 machine. Thanks, -Torsten
