You can do cutting a definite part of an image and put that into another. You just need to use the Paths Tool (press B on the keyboard or see the toolbox to select it) and then create connections around the part you want to get by adding nodes (small circles attached or unattached to one another).
Click the left mouse button while using the tool to create a node, then point the cursor to another area and click to create again. Do this simple steps to
surround the object you want from an image. If you want to
close the connection of
3 or more nodes , just hold
ctrl then lm-click the last node to the first node. This applies for joining any unconnected nodes.
Editing is easy. You can
click first + hold the click then drag to pull 1 of two lines to make a curve connection. You can do this with any nodes and pull there lines to edit.
ctrl + clicking between the connection of nodes adds a node in the middle. To delete a node, just
shift + click over it.
If you accidentally selected another tool and the paths disappeared, don't worry because they are not lost. To see them, go to the paths dialog [add (by clicking the
box with a play symbol pointing to the left -> add tab -> paths) one to the
tabs if it is not present] then double click the path layer to see it or click the first icon of a path layer to see an eye to see the path always.
After making a closed path, choose
selection from path under the
tool options and you will see broken lines. If you can't maybe the
show selection is not checked under
view (ctrl + t).
Make sure that the selected layer is the image where you want to get the cut while copying or cutting or else you might get a blank or something from another layer.That's it. You can cut or copy and get the part inside of the broken lines only. if it is the opposite, maybe the
invert selection is chosen under
select (ctrl + i)When pasting to the same image, unselect first by ctrl + a then ctrl + v to paste. It will become a
floating layer and
shift + click new layer icon or just
merge it or anchor (ctrl + h) to the another layer under it.
You can move layers by using move tool (or simply 'm' on keyboard). Be sure to choose
"move active layer" under tool options
You can also move connection of nodes by holding alt then drag them.
I hope that helped.
