Hey Guys, I have to scale down image of any dimension to a fixed dimension of 135x135, most imp thing I have to maintain good quality of scaled down image. I'm not much familiar with Image Processing algos. Can you guys suggest me any algorithm.

A: 

Unless the input image is square, say 1000x1000, you will first have to crop it to a square aspect ratio (1:1) then scale it down to 135x135 pixels.
