You want a "pdftex.cfg" file which contains "imageresolution

Here is mine:

% Thomas Esser, 1998, 1999, public domain.
output_format 1
compress_level 9
decimal_digits 3
page_width 210truemm
page_height 297truemm
horigin 1truein
vorigin 1truein
% pdftex.map is set up by texmf/dvips/config/updmap
map pdftex.map
% This shows how to add your own map file.
% Remove the comment and adjust the name:
% map +myfonts.map
image_resolution 115 

All the lines apart from the "image_resolution" come from the defaullt

Getting a decent resolution figure is hard work - there is no right way.
It depends on the resolution the images were created at the resolution
you are viewing them at. The above figure gives reasonable results for
screenshots created at 800x600 screen resolution and printed from
"acroread" to A4 paper.
