How to keep the resolution of an image when scaling it in Gimp


Question

I want to copy and paste one picture into another one using Gimp.

I have a picture with 200x200 pixels and 72dpi. The 72dpi are not enough to print the image in the size specified in its header. Therefore, I want to reduce it to half its printing size, but keep the 200x200 pixels to get to a 144dpi resolution.

Since the picture I'm pasting has rather low quality, I want to reduce its size within the other picture and at the same time increase the resolution (that is, keep the number of pixels constant).

However, the only option I found was the Print Size function, which does not seem to affect the size of the pasted image relative to the picture it is pasted into.

Accepted Answer

After pasting the picture, you'll see that a new layer will be formed named "Floating Selection" Right click on it and then click on "New Layer".

Now it has become a layer. Again right click on that layer name and select "Scale Layer". Now you can scale this layer relative to the main Picture.

Lemme know if your problem is not solved. :)
