The Lasso Tool allows you to freely draw an arbitrary shape to select parts of an image.
Click, hold SHIFT and click again to create straight lines.
Selection tools support four different modes:
- "Set" replaces the current selection with a new one.
- "Add" keeps the current select and select new areas in addition to the already selected ones.
- "Sub" deselects already selected image areas.
- "Mul" only selects image areas have already been selected, and deselects areas which are part of the new selection.
