DPI loss

Open koalito opened this issue 5 years ago • 2 comments

When i run the process, yes the resolution is x2 result but i lost the DPI settings. So for screen results it's good but for printing it's not really interesting.

Can you do something about that ?

I am not familiar with printing, but DPI is just metadata so it can be set any value. But I do not know if DPI should keep its original value or if it should be 2x.

Some references for DPIs, IMO if the image got 2x then the DPI would be reduced by half.
