Helpinator comes with image editor. With it's help you can add various shapes to your images and screenshots. Shapes are stored as vector data but at compile time Helpinator converts them to raster images.
To activate Image Editor select image under "Images" node in the project tree view. Image editor tool bar is at the top of image preview area. Now select Tools->Activate Editor.
From Tools menu you also can:
- Extend Image canvas. This is useful when you need more place for shapes.
- Replace bitmap. Use this feature when you want to keep shapes but some interface elements on your screen shot have changed.
