To rotate an on screen image, right click and select Rotate. You may rotate the image right or left in 90-degree increments.
You may also use the CTRL–L and CTRL-R hot keys to rotate an image left and right respectively.
Note - Since rotating an image changes it, Sanction II will automatically save it if the auto save rotation option is enabled. The image must NOT have it’s read only file attribute set in order to save it successfully.
