Scale without resize

using Augmentor
using ImageShow, ImageCore
using Random

In the case that only a single Zoom factor is specified, the operation will assume that the intention is to Zoom all dimensions uniformly by that factor.

In [2]:

img_in = testpattern(RGB, ratio=0.5)

mosaicview(
    img_in,
    augment(img_in, Zoom(1.3)),
    augment(img_in, Zoom(1.3, 1));
    fillvalue=colorant"white", nrow=1, npad=10
)

It is also possible to pass some abstract vector(s) to the constructor, in which case Augmentor will randomly sample one of its elements every time the operation is applied.

In [3]:

Random.seed!(1337)
img_out = [augment(img_in, Zoom(0.9:0.05:1.2)) for _ in 1:4]

mosaicview(img_out...; nrow=2)
