Probably a longer answer than you need, but it might be helpful to address the larger issue of the appearance of GRASS screen output.<BR>
<BR>
I originally wrote d.out.file, the successor to d.out.png (my first GRASS script written to solve the complete lack of screen->to graphic file output in version 5). It will only work with the xmon screen displays because it uses d.save to capture all xdriver commands used to create the screen, and then plays them back with the output set to PNG (or PS with Hamish’s update). The display in the TclTk and wxPython GUI is generated by sending all d.* commands directly to the PNG driver. So d.save never captures these display commands. For this reason, d.out.file will not work with the GUI. <BR>
<BR>
The GUI does save the screen to various formats, including EPS.<BR>
<BR>
The high resolution in d.out.file is a bit of a problem. It achieves this by setting the size of the output graphic to some multiple of its current width and height in pixels before rendering to the PNG driver. This can put more pixels into the output graphic file. However, it also causes problems with vectors (lines get increasingly thin with increased resolution), scales (the scales get shorter vertically and type gets smaller), and possible some other features. <BR>
<BR>
Explore mode in the TclTk GUI and normal mode in the wxgrass GUI no longer tie the number of pixels in the display to the resolution of the raster. So you get a nicer output image from the screen without the distortions introduced by the method used in d.out.file. Text is rendering a lot nicer too because native GUI text can be used for manually placed text objects and there is much better rendering of TrueType fonts in any text output from the PNG driver now. Vectors can still look pixelated, however, until we have a different method of rendering them.<BR>
<BR>
There is ongoing discussion of making a better interface to ps.map to produce nicer output too.<BR>

d.out.file is a very very useful script because it prints at high resolution...<BR>
