Re: [Gimp-user] reduce resolution while retaining image size on computer

[Richard <strata_ranger hotmail com>]

I was about to suggest the same thing.  GIMP only ever displays the image onscreen relative to its raw image 
pixels and zoom % (ignoring any physical print resolution / dpi).  If all you do is change the print 
resolution of your image, the image's size and data (in pixels) remain unchanged, thus there is no visible 
change in how GIMP displays it.  Conversely, any time you resize/scale the image itself -- even if you also 
change the resolution to maintain a fixed print size -- the image as seen in the GIMP window obviously 
changes, because it's displayed relative to image pixels and zoom % only.

An option to adjust GIMP's current zoom level to reflect changes in the current print resolution might be an 
idea here -- the least obtrusive method could be just a checkbox ("Zoom to new size" or something) on the 
Scale Image and Print Size dialogs....
