dpi does not change

[rjhanson]

Hello,
I use to be able to go to the "scale image" function and change the x/y resolution, lets say 72 to 300.  I hit scale now, it closes, I reopen and it says that the resolution  has changed, image size has not, which is a bad sign.

I Save the file to "webP" and reopen, only to find in the properties that the file is the same size and the resolution is still 72 dpi.

I would say this function is not working correctly anymore, but it was in the past.

Anyone see where I am messing up?

Thanks
Richard

hmmm....no

Gimp images are sized in pixels and if all you do is change the resolution, nothing is scaled. This is the same as using Image -> Print Size  Example of a before after, resolution changed, image size in pixels the same, real world units ( inches = print size ) changes.

Best guess. You have not enabled Exif data where the resolution value is held.
