I'm using Gimp to create maps. What I would like to do is use the rectangle selection tool to copy a section then blow it up (in a way that gives new picture has as many pixels as the original) and continue adding more detail. So if I start with a map that has 1000 by 1000 pixels and I copy a section that is 100 X 100 I want to expand it to be as large as the original picture (it will have rough edges now) but with 1000 X 1000 pixels again and then use gimp to round off the rough edges and add detail. I'm probably not being clear. If I were to do this "by hand" I would expand the 100 X 100 section, take a screen shot, import the screen shot into gimp which would give be a larger picture of the 100 X 100 area with more pixels. Although this kind of works it doesn't completely because I have a hex grid layer that I want to lay on top so things have got to be exactly the right number of pixels. Hope this makes sense.

I think you might have a problem, but why not try taking a 102x102 selection, blowing that up 10 times then taking a 1000x1000 selection of that for nice clean edges? However, as I said, you might have other problems, so just try it Owen

Doing it your way you see what is known as 'aliasing'. For a description see: http://www.widearea.co.uk/designer/anti.html Surely a better way is to take your 100x100 clip, then from the 'Image' menu, use 'scale image' to scale to exactly 1000x1000. Try the different interpolation methods but possibly Sinc(Lanczos3) in this case. This will apply a degree of anti-aliasing. I've just done a quick comparison and the resized image is much 'softer' than the screen capture so the next step is to sharpen the new image. I found 'unsharp' mask worked best - that's in the 'Filters' -> 'Enhance' menu. Experiment with the radius and amount settings. Remember whichever way you choose, you can never replace detail that is not there in the first place. -- rich

That's just what I needed. I have a lot to learn about using the Gimp but I am getting better. I now see the huge value in using layers! If done right it cuts the work I need to do way down!
