Segmentation

Segementation create raster bitmaps. You can use various shapes to add or remove pixels.

When you draw a shape using segmentation labels, it's like painting an image with the shape, thus it doesn't keep points of the shape once you drew it.

If you want to modify the shape of a bitmap, you need to add more pixels using a shape or use eraser tools to erase unwanted pixels.

Vector

Vector shape consists of single or multiple points.

Edit a shape

You can use the Selector tool to select a shape. You can move or delete the entire shape, or edit an individual point to modify the shape.

You can double-click a point to remove it.
