GIMP/Scissors
The Basics

Shortcut: I
Scissors is an interesting selection tool. It has some features of lasso, some features of paths tool and some of its own. It is useful for selecting a region defined by strong colour changes at the edges. To use scissors, you need to create a set of 'control nodes' (also referred to as anchors), at the edges of the region you are willing to select. The tool creates a curve through these nodes, following any high-contrast it can find. Each time you press left mouse button, you create a new anchor that is connected to the last control node by a curve. If you want to finish the selection, just press on the first node you've created. After that you can adjust the selection by modifying the curves or by moving/creating new nodes. When you are satisfied just press anywhere inside of the selection to create it.
- Modes - determines the way of creating the selection, whether it'll be combined with existing one and such
- Antialiasing - causes the boundary of the selection to be drawn smoother
- Feather edge - causes the boundary of the selection to be blurred
- Interactive boundary - the curves will be created instantly after creating a new node

Interactive boundary
[edit | edit source]When this option is active, the curves between nodes will be really curves. Normally (when the option is disabled) there will be only straight lines until you finish the selection.
