simple things should not be that difficult to do

[yggdr4s17]

I am getting so frustrated I might be stupid, but it should not be that hard 

 

if I see a picture on internet lets say a logo with a white background or any background and I do not want the background 

 I would say all I have to do is right-click on the image select "copy image" past it in the software Ctrl+v use flood selection for the white background then select invert selection and then just Ctrl+c and Ctrl+v, and it should only past my selection... but it does not it just copie past the same picture with the dam background what am I possible doing wrong I do not want to use the erase tool its to slow and not accurate, and it should not be the way to do it in the first place

 

using affinity designer

 

EDIT: i found the issue wish also in my opinion should not be an issue and would nice to get changed if possible in a future update

 the problem is that I did not first save the file on my computer and then dragged it into affinity 

but did copy it from Google and paste it into affinity but why does it matter both ways show the picture in the software why not threat it the same way?

The first way you probably did it in such a way that you got the equivalent of File > Open, which opens the image directly as a Pixel layer.

The second way would be the equivalent of File > Place, which would give you an Image layer, instead. To work with individual pixels of an Image layer, you must first Rasterize it so it becomes a Pixel layer.
