Exporting a circle into a new picture.
So i want to cut a coin out of a picture and export it to a picture with the sidelength being the diameter of the cut out coin.
How am i able to save it in a new picture with that size without the white space around it?

From the start:
Use the elliptical select tool. Set the aspect ratio to fixed and 1:1
Move the selection around until it borders the coin.
like this: http://i.imgur.com/XaB21QF.jpg

Now go to the edit menu and select copy.
Still in the edit menu select paste as -> new image
You should get it looking like this, the image is the diameter of the coin and the chequer pattern denotes transparency.
like this http://i.imgur.com/bdQxL6D.jpg

To keep the transparency,
Go to the File menu and Export. When asked for a name type whatever you want and add .png at the end.
If you use say jpg or bmp then the transparency is flattened to white.
