Change Output Image Resolution

[Stephen Lime]

Nope, the 72 DPI is a constant (although you could change it and recompile). Since all that the DPI value affects is scale you could fake a higher resolution by doing the following in MapScript:

  - do a $map->prepare() (this calculates scale)
  - change $map->{scale} to reflect your desired output resolution
  - now loop through the layers and do a $layer->draw()

Hi all
 
Is it possible to change the resolution of an MapServer output image from 72
dpi to higher resolution via MapScript??
 
Best regards
