Smart way of changing aspect ratio for DVD-menu still images or digital photography. ReAspect is a very straightforward, stand-alone software. Load image, then adjust the few settings until the image looks fine, then save it. You can crop the 4:3 image or you can stretch the image in your image manipulation program. Neither will work very good and here is why:
1. Cropping: you are losing part of the image and resolution. If the original image had 480 lines, after cropping it to 16:9 you will have only 360 lines, but more importantly part of the visible image is lost.
2. Stretching: If you stretch the image, then you are reusing all the pixels, but the result has incorrect aspect ratio - image looks "fat".

Limitations:
* Watermark on the output images
