Image manipulation with Fotoxx
Fotoxx includes the ability to straighten up sloping lines that occur, for example, when the edges of the subject you are taking a picture of are not parallel to the camera's geometry, such as a tall building. To fix undesirable effects like this, click unbend and then experiment with the values for vertical unbend and horizontal unbend. Fotoxx does not offer a real-time preview. Instead, you must Apply the settings to the image first, and you can then make changes before pressing Finish to permanently apply the changes to the image.
If I had just used the program's special features, it would have faired well – the HDR and panorama features work perfectly, but users would probably appreciate more transparency in the approach. Unfortunately, Fotoxx's basic functions are spartan and the unusual controls are just plain pesky. On top of this, the program could be far faster. If you want to retouch images, stick with GIMP, but if you want to experiment with HDR and panoramic images, check out Fotoxx.
