Re: [Matplotlib-users] LaTeX, eps, ghostscript, and the like

[Darren D. <dd...@co...>]

Are you using NumPy, Numeric, or numarray, and what version? What backend, 
GTKAgg, WXAgg? I'm grasping at straws here, maybe there is a problem with 
backen_agg's draw_image on your platform or with your configuration, but I 
can't investigate because I can't reproduce the problem.

Also, please try running dvipng -bg Transparent -D dpi -T tight dvifile, 
replacing dpi with numbers like 60, 80, 100, 140, just to make sure that 
dvipng is producing scaled images that look correct.
