How to rotate image by less than one degree?

Question

How to? Simply enter 0.5 (or what ever the angle you require) into the dialog. Which software? Most would have this feature I'd expect. — ChrisF, Nov 13 '12 at 11:41
The most known free image manipulation software should suffice: GIMP — Ярослав Рахматуллин, Nov 14 '12 at 02:53

Rotating with fractional degrees isn't something special. If a program doesn't allow it, it's probably a UI design choice of the developer.

IrfanView, for example, supports fine rotation:

IrfanView is freeware and it supports both automation (via command-line options) and batch processing.

Since you are talking about an image I would suggest a rotation matrix. See here for an example: http://en.wikipedia.org/wiki/Rotation_%28mathematics%29#Two_dimensions You can use arbitrary values as angle argument.

There's no indication in the question that the OP is coding a solution. Equally there's no indication that they're using some image processing software to do this either. – ChrisF Nov 13 '12 at 12:25
