= Project Name Goes here Rotate90 =

I kept things very simple and created a function that rotates an image 90° clockwise.  Then, I then profile and evaluate performance of rotating a tiny, medium, and large sized image file 12 times each.

:;[http://cimg.eu/ CImg] :: Download and extract the CImg Library (Standard Package). This provides the template class used to store image information. The library contains many useful image manipulation functions and methods, including rotate, but we will only be making use of the CImg class and the Display function. Make sure your project include path can find CImg.h, which should be located in the root of the extracted files. :;[http://libjpeg.sourceforge.net/ libjpeg]

::libjpeg provides the functionality of reading .jpg file data into a CImg object. It's not quite as strait forward as getting CImg, as you need to compile libjpeg from source. I used the most recent (Jan 2018) version named jpegsr9c.zip [http://www.ijg.org/files/ from this listing].

::If you have trouble building the solution, [https://stackoverflow.com/questions/46055720/cannot-load-any-image-with-cimg this article on Stackoverflow] helped me compile it.

::Once libjpeg has been built, it should result in creation of "libjpeg.lib". Be sure to link this file with compilation of the project code.
