I'm a beginner in the field. Please help me solve a problem. I have a 2500x3500px image, which I have uploaded in GIMP, to make part of it transparent. Then I wanted it to be downloaded with 300 DPI. Although I set the "Scale Image" to 300 DPI, when I downloaded it, I only had a 120 DPI image.
I made several attempts but to no avail, GIMP refuse to download the image at 300 DPI.
Where am I going wrong?
Thank you.
Scale is the wrong tool for this. Gimp works in pixels 2500x3500 is constant regardless of ppi(dpi). The only effect is when you come to print, the printer will use the ppi to size the print.
Open your image, do what ever is required.
Use Image -> Print Size. Set the units to pixels/in (if required, some will have pixels/mm) Change the x resolution and y resolution to 300.
Save as a Gimp .xcf file or Export as a png to retain the transparency. Make sure Save resolution is ticked in the png export dialouge.
