CENTER_OUTSIDE
Scales, maintaining the original aspect ratio, so that one of the image's dimensions is exactly equal to the requested size and the other dimension is greater than or equal to the requested size.
This method will upscale if the requested width and height are greater than the source width and height. To avoid upscaling, use AT_LEAST, AT_MOST, or CENTER_INSIDE.
On pre-KitKat devices, Downsampler treats this as equivalent to AT_LEAST because only power of two downsampling can be used.
