Copy and Paste of part of a rasterized image does not work as I would expect

[AGain]

Dear Community, I ask your support to understand this behaviour as it happens only with AD2 and not with other softwares. (I have the macos version)

1. I have an image (just a screenshot from an old videogame)

2. I import it as usual in AD2 first with the place command tool. Note the both the empty document setup is set a 300dpi and also the imported image is 300dpi.

3. after I import it , I switch to Pixel Persona

4. My objective would be simply to duplicate a part (the little monster sprite), therefore I first rasterize the image

5. then I use the square marquee tool and copy and paste (see the video attached) the part I want. 

6. Result is a downgraded pixelated copy of the original pixels which is not what I want .

Of course I could go to other softwares to do this thing... but what am I doing wrong ?

 

Thanks in advance

It seems like you try to place the pasted part onto fractions of a pixel. Activating "force pixel alignment" should solve the problem of anti aliasing the sprite.

@Andy05 ... 😔 yes you are right ... so I learned another thing here .... Reading the help it says: "If this option is switched off, objects and selections can occupy partial pixels."

I didn't even imagine/know that a selection could be moved by PARTIAL PIXELS. It would be interesting for me to understand in which use case someone would use this partial pixel allocation, but this is another story maybe...
