Someone told me a while back it was virtually impossible to create a circle with the paths tool that was perfect in circumference.Well i have figured out how to do it.It is very simple.
First open Gimp i am using Gimp-2.7.5 (new Partha version)
Open the layers dialog CTR + L
Open the Paths dialog Windows>Dockable Dialogs>Paths
Now create a new document - File>New
Make it any size as long as it is square - I am using 480x480
Now go to View>Guides - Also make sure snap to guides is selected
Create 6 guides and position them like so on your image
Now click on the the paths tool
in your the toolbox
Create 4 new nodes/points in the center of your image Image example below
Now making sure that the
design option is selected in the path tool options dialog move the center of each side out from the center -image example below
Now you will notice two of the nodes on the left are both already simultaneously selected.
Pull both of them by selecting one and move them in towards the other two like so - image example below
You can also do this by selecting the circular selection tool
Creating a circle then doing a Select>To Path
Then stroking the path.
I just wanted to show you how to do it with just the paths tool.Now we know it is possible.
