Rotate Image

I want to rotate an image so I can traverse it across the horizontal rather than the vertical. I see that there are various rotating functions in IPP. These functions all suport rotations at an angle. I just want to move some pixels around, no blending needed.
I need something very simple, similar to the Ipp mirror functions.
Heres what I need:
Before:
1 x x 2
x x x x
x x x x
3 x x 4
After:
2 x x 4
x x x x
x x x x
1 x x 3

Hi,
Have a look at this thread.
I posted some samples of how to use Mirror/Transpose to do 90/180/270 rotations. Someone also commented on this thread how to improve speed using a negative step to avoid the mirror function. Regards, Matthieu

Please check if ippiMirror or ippiTranspose functions fit your needs.

HI there

It is so difficult for me to rotate image or process image without an image processing tool.

I have tried a free trial from an image tool.It works fine.But it is a little bit expensive.So i want to know that

if there is any cheap tool.Thanks a lot.

Hi Marrisa,

"cheap" (guess) means "free" - so the best one is OpenCV library (I think)

regards, Igor
