Point Data

Overview

The Points widget appears when Points are enabled in the Feature Tree. It’s designed for viewing, styling, adding, and editing keypoints visible in the Media Viewer.
If you haven’t loaded a keypoint dataset, you can still add keypoints; these changes will be tracked in the Data Manager (see Data Manager → points [link user-ref here]).

Note

Saving and Export: Any additions or edits to keypoints are recorded by the Data Manager and can be exported later as part of your dataset.

Widget Layout & Controls

Color & Opacity

  • RGB (0–255): Enter the Red, Green, and Blue channels to set the keypoint color.
  • Hex Color: Optionally specify a color using a hex code (e.g., #FF6600).
  • Color Preview: Shows the current color selection.
  • Alpha: Controls opacity/transparency of the keypoint in the Media Viewer (higher = more opaque).

Size & Shape

  • Point Size: Sets how large the keypoint appears in the Media Viewer.

    Note

    Data size vs. display size: The stored keypoint in the Data Manager is always one pixel (a single coordinate). Point Size/Shape only affects on-screen display, not the underlying saved data.

  • Marker Shape: Choose how the keypoint is drawn in the display:

    • circle, square, triangle, cross, x, diamond

Adding & Editing Keypoints

  1. In the Points widget, find Mouse Mode (dropdown).

  2. Select Select Point.

  3. Click anywhere in the Media Viewer to add a keypoint at that location.

  4. To modify a keypoint, use the same mode to select it and then adjust its location in the media window.

    Note

    Deleting Keypoints: To delete accidentally added or misplaced keypoints, open the data manager and find the frame that contains the keypoint and delete it (see Data Manager → points [link user-ref here]).

Tips

  • Keep Alpha low to ensure that imagery remains visible under points.
  • When working with multiple keypoints, use distinct shapes or colors to differentiate labels, annotators, or classes.
