Freeform Tool ### **Usage and Conversion** * **Drawing Process:** Unlike the click-by-click method of the Polygon Tool, the Freeform Tool allows users to draw shapes freely as if using a pen. * **Auto-Conversion:** Once the stroke is completed, the platform utilizes a path simplification algorithm to automatically convert the freehand drawing into a structured **Polygon**. This ensures that the final annotation remains editable and compatible with standard segmentation formats. * **Finalizing:** Releasing the mouse button or closing the loop automatically triggers the conversion process. ### **Interactive Toolbar: Drawing Modes** The Freeform Tool shares the same operational flexibility as the Polygon Tool. Through the **Interactive Toolbar**, users can select from four distinct modes: 1. **Overwrite:** The new shape is drawn independently. 2. **Subtract:** The freehand stroke cuts out a section from an existing polygon. 3. **Auto Subtract:** The platform automatically trims the freeform shape so it does not overlap with existing boundaries. 4. **Union:** The new freeform shape is merged into a single logical entity with an existing polygon. ### **Customization: Point Density** The precision of the freeform-to-polygon conversion can be adjusted to match the complexity of the object: * **Point Frequency:** Users can control how many vertices are generated during the conversion. A higher density captures more detail, while a lower density creates a simpler, more manageable polygon. * **Configuration:** These settings are located under the **Freeform Settings** section within the **Canvas Settings** menu. Adjusting the frequency allows for a perfect balance between speed and geometric accuracy.
