In the last post we saw how to correct the aspect ratio of a video. Here is how you can edit an image to its correct sizes using GNU Image Manipulation Program (GIMP). For this I first reduced the image height. And that’s why it is seen as stretched. Now lets see how we can correct this.
1. Open the image in GIMP
2. Goto Image»Scale Image
3. Click on the Keep Aspect ratio Button (the small chain like icon next to the pixel box)
4. Change one of the dimensions (either height or width) to make the image to have a sensible shape
5. Save it.
The video is a screen cast of me doing the above procedure with an image of my favorite bike.
