How to Make a Jagged Edge Smooth in GIMP
If you have an image or photograph that features jagged edges, you can use the free graphic program GIMP's IWarp tool to smooth out the uneven lines and create a seamless result. Regardless of the size of your image, you can customize IWarp's deform settings to suit it. The tool will also work with any colors and any angles.

Select "Filters," "Distorts" and "IWarp." The IWarp tool will open in its own dialog with a preview box of changes made and a list of deform settings. For relatively small jagged edges, you may want to keep the "Deform radius" small. For large and exaggerated roughness, you may want to increase both the "Deform radius" and "Deform amount." Keep the "Mode" as "Move," regardless of whether you do this.
