change resolution preserving subfolder tree structure

[danjde]

Hi friends!

I'm writing because I try to change the resolution (from 300 to 72 dpi) of many many different png files contained in many many subfolders from a main, while preserving the original structure tree and overwriting files modified

is it possible with ImageMagick?

many many thanks!!

Yes, but you'll also need some script.

ImageMagick can change resolutions of the png files within a single folder, but it won't recurse into subdirectories. You'll have control that with your favourite shell.
