  • Manual: only updates on user command.
  • Interval (100 ms): updates based on the user-set interval rate (for 100 ms).
  • Every nth frame: updates based on the user-set frame rate.

• Background Opacity defines the transparency level of the stream on a 0-100 scale.

• indicates the topic is not available.
• indicates that the topic is loading.

Historical Image Display

UVAP Image Stream Window

UVAP image player can be used to display a single frame from an image stream. Timestamp defines the timestamp of the frame to be displayed.

If there is no frame in the chosen topic with the requested timestamp, UVAP image stream behaves the following way:

• If the requested timestamp is smaller than the timestamp of the first frame in the stream, the first frame is displayed.
• If the requested timestamp is larger than the timestamp of the last frame in the stream, the last frame is displayed.
• Otherwise, the frame with the timestamp immediately after the specified timestamp is displayed (the frame with the closest timestamp that is bigger than the specified one).

An icon next to the topic field indicates the status of the topic:

• indicates the image is not available.
• indicates that the image is loading.
• indicates that the image is online.
