Automatic Scaling (not working)

shadowlordDEA

good evening everyone ^:)^
Today, I studied a lot about the best scales.
Then, on a new project, I added a picture (480x800):

local background = Bitmap.new(Texture.new("Menu_Inicial/imagens/menu_bg.png", true)) stage:addChild(background)

I saved another smaller picture, with the suffix @ half.
and added in the properties window of the project. (with "crop" selected)
when I run the project, and change the resolution, it works normally, and shows the image smaller.

But when I did the same with my original project, (different images, but the same resolutions), does not work. He does not load the smaller picture. :-(
what might be happening?
I have tested several alternatives, but nothing happens.

Thank you all for reading.

I solved the problem:
I was using the wrong scale.
