First off, I don't use Gimp that often, so what I'm asking may be simple and I've missed something obvious. But...
I'm trying to modify the following image in Gimp. The image size is 489x63 however I need it to be 500x20 but most importantly I need each end to remain the same shape without distorting (i.e a perfect semi circle). If I scale (unlinked) to the required size the ends distort an become squashed.
I've tried scaling (linked) to the correct height 20px which makes the width 155px, but then I couldn't figure out how to essentially stretch the middle section until the width was 500px.
Any help appreciated
