Tutorial

Brightness and Contrast Control


This tutorial demonstrates how to implement brightness and contrast controls for your map application. These visual adjustments allow users to customize the appearance of imagery to improve visibility and highlight specific features.

You'll learn how to:

  • Adjust the brightness of the map imagery using slider controls
  • Modify the contrast of the map imagery using slider controls
  • Reset brightness and contrast values to their defaults
  • Update the UI to reflect current brightness and contrast values

These controls are particularly useful for enhancing visibility in areas with challenging lighting conditions or when analyzing specific terrain features. The brightness and contrast adjustments are applied in real-time to the map display.
