An image represents a grouping of primitives and/or other images. Images can contain other images forming a hierarchy. To create an image, select the shapes to be grouped using the <Shift> key, then select the "Layout/Group" option. The resulting group will be shown bounded by the green selection box. Use the "Layout/Ungroup" option to destroy an image.
An image is selected by clicking on one of the primitives within it. Repeated selections of an image will select the shapes within it. You can select primitives directly by clicking on them while holding down the <Ctrl> key.
Shapes can be removed from an image by selecting the shape and using the "Layout/Remove from group" option. You can also add shapes to an existing image by selecting first the shapes, then an image, then using the "Layout/Add to group" option.
