Choose one of three functions from the toolbar to the left: selection tool, polygon tool, and magic wand.
Selection tool is used for existing polygons (see 3. for a definition of a polygon)
Polygon tool is used for creating polygons by connecting vertices
Magic wand creates a polygon automatically. So far, this works with most panels, speech balloons, captions, and onomatopoeia, but not with visual objects such as characters, background figures, etc.
Double-click on the annotation tool you want to use (panel, speech balloon, caption, character, onomatopoeia)
Start clicking on the edge of the element you want to annotate. This creates a vertex – the next click creates another vertex and so on. The area surrounded by vertices is a polygon. The polygons comprise the annotation layer “over” your image. Each polygon should be congruent with its corresponding element.
You can finish the polygon either by double-clicking or by reselecting any of three cursors. If everything went OK, you’ll be able to see the polygon in the “Tree” tab in the bottom right window
Fill in relevant data about your annotation in the upper right window (e.g., character name, speech bubble content, relations to other characters in the panel, etc.)
