I am trying to do a spotlight search to find images in a particular directory that have have a specific "pixels per inch" value (popularly referred to as "DPI")...Does anyone know how this can be done using spotlight?

I am sure this can also be done using an AppleScript or an Automator action somehow, but I am specifically interested in figuring out which of the various spotlight advanced search criteria would permit me to weed out such images...

In the 'Other..." list of Spotlight advanced search criteria, I've found "Resolution Height/Width", "Pixel Height/Width", and a few others that seem like they might be a good starting point to search with, but nothing has allowed me to narrow down my searches for images that are, say for example, 72ppi or 300ppi (aka ~ 72dpi or 300dpi).

Any suggestions would be greatly appreciated... Thanks!

I don't have an exact answer, but isn't "Pixel Height/Width" what you are looking for? For example, wouldn't a pixel height and width of 1/72 of an inch equal 72 dpi?

Pixel height/width would be aspect ratio; either of the image or the individual pixels (they aren't necessarily square).

So is there a way to use spotlight to search for images based on their resolution, or not?
