Hi,
I have some code which swap layer in exact position but not in size,

What i want is swap layer position and same size, like this:

Can anyone help with this?
Thank you.
1 Correct answer
You can try this. It will only resize base on width.

IMO you would introduce to much distortion with image layers solid color layers will work ok. Only if the layers have the same aspect ratio will the resizing not distort. Like your example where both layer have a 1:1 aspect ratio.
It is not hard to script all you are writing is you want to move two layers and change these layer sizes. That is easy to do using the two layers bounds. You are moving the layers center point to the other layer's center point and changing the layer width and height to the other layer's width and height. That is just two transform you are doing. However, layers like shape, text, image, smart object etc all will distort if the two layer do not have the same aspect ratio. The layer's width and height will be changed by a different percentage. The layers content will distort.
In the example above both image are 8.2MP 16bit color smart object layers from ACR one has a Landscape 3:2 aspect ratio the other a portrait 2:3 aspect ratio after the two transform both still have 8.2MP but the portrait has been distorted into a 3:2 Landscape aspect ratio and the landscape into a 2:3 portrait aspect ratio.
of course i will not do for photo that have different ratio that will make distortion, 
Hello, Chuck Uebele
Can you please help me again, the previous script is only for 2 layers,
What about some layers, I take for example 6 layers,
every time I run the script it will change randomly swap the layer, and if I repeat the script it will change randomly again
please see the example below:
and this is not limited to a number of layers, it is possible for me to select 100 layers, and the script will swap randomly,
can this be done?
if you can help me make the script
Thank you very much...........
Chuck Uebele
A very interesting script
when I use it I have a problem the images exchanged move to the left or right
how to avoid this problem.

I also noticed this same problem, always moving to the right or left.
Your original request was and you want to support many layer types
Swap Layers In Exact Position And Size
I was worried about the size aspect of you request. I did some more thinking about Size. If you think about layer size. A layer has a rectangular bounds. the rectangle has a width and a height the Width Pixels time Height = number of possible pixel the layer can have. For the layer can be ant shape that rectangle area even text. So if you resize based one the total number of pixels you can retain the layers aspect ratio and the image within the area will change in size but will not. So I fixed the positioning Problem I had in my script based on Chuck's first script and change the resize to be done for the number of pixels a layer can have. If the two layers are different in size their layers will be resize for number of possible pixels and the layer content will not distort. Text will change size as will images however the layers content will not distort. The resize will be a constrained resize. So here you go.
