Smoothing Curves of Enlarged Images
Enlarging an image results in pixalization becoming very obvious. Is there a way to smooth the curves of the enlarged image?

RE: Smoothing Curves of Enlarged Images
IMO, it depends on the picture and it takes trial and error (and also remembering where the undo button is!)... But I'll give you an example of what I did after resizing my avatar to 500x500.

I first did an Unsharp mask (underneath Filters > Enhance) and I tweaked the setting until it looked decent (Nothing too crazy). Then I hit okay or whatever and I did a VERY SLIGHT Gaussian Blur to smooth it out. But, it all depends on the image as no two images are the same.

Of course, pixilation when getting an image blown up is expected and cannot be fixed completely or even close to completely (As you can see in my now huge avatar)... So you have to improvise.

All sorts of ways,
First thought was a step-resize script, but it's broken on gimp 2.8 so a look at G'mic, play around with the settings. It might be ok but remember every image is different, and never expect much from a very small image to a large image.
