DPI-settings lost after using PNGOUT

  Hi,
  
  when I compress pictures including dpi-settings with PNGOUT, these informations are lost afterwards.
  
  Is there a switch that tells pngout to keep the dpi-setting?

  Cool, this was exactly what I was searching for.
  I already guessed it was as easy as this but wasn't able to figure it out by myself before.
  
  Thanks!
  
  Edit: Sorry, but it seems I was a little hasty. I just tried the IrfanView plugin to test your solution (and it worked).
  Now I tried it with PNGOUT commandline version and it doesn't work anymore. Does this switch only work for a png input? Because I tried it on a bmp with no effect. Though if I use a png as input it keeps the dpi-information.

  Your observations are accurate.
