Recently I have been trying to rotate a JPEG image that was taken by someone who was holding the camera at a slight angle. Furthermore I think I only need to rotate the image by about 5 degrees counter clockwise.
While trying to find a solution I have come across a number of individuals saying that some picture quality is lost when rotating JPEG's, so I would need to use some sort of JPEG lossless rotator. I tried out two so far, however none have the option to rotate the image by only a few degrees, but rather the default 90 degrees option is given.
So to sum up, I need to rotate my image by about 5 degrees counter clockwise, preferrably without losing a noticeable amount of picture quality.
