Is a linear transform on an Image supposed to be applied in place?

[baba-yaga]

It seems Image.clone() does not pick up applied transforms, or these are not applied in place, as the documentation suggests. Consider an example:

from vedo import *
img = Image(dataurl+"images/dog.jpg")  # 3D embedding of the image

plt = Plotter(axes=1)
plt += img.alpha(0.5)
img1 = img.clone().scale(0.5)
plt += img1.shift((-100, -100, 100))
plt.show().close()  # result as expected

The result as expected:

Now, use img1.clone() instead:

plt = Plotter(axes=1)
plt += img.alpha(0.5)
img1 = img.clone().scale(0.5)
plt += img1.clone().shift((-100, -100, 100))
plt.show().close()  # scaling is lost!

The scaling is lost! It look that it is img but not img1 is cloned

Thanks - I just fixed it in the master.

from vedo import *

img = Image(dataurl+"images/dog.jpg").alpha(0.75)
img1 = img.clone()
img1.scale(0.25)
img1.shift(-100, -100, 100)
show(img, img1, axes=1).close() 

img = Image(dataurl+"images/dog.jpg").alpha(0.75)
img1 = img.clone()
img1.scale(0.25)
img2 = img1.clone()
img2.shift(-100, -100, 100)
show(img, img2, axes=1).close()
