How to crop and resize an image for a LiveTile

I would like to be able to add an image to a live tile so that there is no stretching and the image looks normal. I am getting my images from the PhotoChooserTask, which contain images from the medialibrary. As of now I can successfully place an image on a live tile, but it is stretched and the aspect ratio is not correct. How would I be able to find the aspect ratio of the image and crop the image so that it ends up being a square with dimensions 173x173 with no streching? I have followed a couple tutorials found online but nothing seems to accomplish this the way I need it to.

Solution

I accomplished this by referencing Resize image for Live Tile - WriteableBitmapEx which proved to have the correct implementation.
