Auto-Flicker

Auto-Flicker

The SPEAR Auto-Flicker tool provides a way to compare two dynamically linked images. Auto-flicker toggles between images at a desired speed using one of three methods: blend, flicker, or swipe. The auto-flicker playback can be saved to an animated GIF to examine and share results.

  1. Select a display method using the provided drop-down list.
  2. Control the operation using Play, Stop, and the speed slider.
  3. Optionally, click Save to save the operation as an animated GIF.
    • Because GIFs are saved in a maximum of 256 colors, animated GIFs may experience color loss.
    • The speed at which the saved GIF animation plays in ENVI may not match its speed in other applications.
    • Animated GIFs can contain many frames and therefore can be large in size.
