v.resize v.resize crops and resizes streams. v.resize crops and resizes streams. Zoomed pixels are interpolated to remove jaggies and aliasing. You can set the output width and height, and the source rectangle. Alternatively to setting the output dimensions, you can specify the destination rectangle, which resizes the stream to the rectangles width and height and attaches the top, left coordinates to the stream which can be used by v.composite objects downstream.
