Bitmap re-scaling issues (width & height)

I’m working on a project where I have to shrink a an images height and width down, but when I try to reset the height and width, the image remains the same size. No errors are thrown, it simply does not return to it’s normal size.

In the example below, the car in the array begins at 200 px, I change it to 129, but then try to resize it back to it’s original size. It’s remains 129. I cannot figure this one out

car[counter].width = 200;
//trace shows "129"

Do you have a way to share more example code, where we could try and determine the issue, here?
