KB10375 - Update screen and retain map extent after each modification.

To update the screen after making any modifications (vector edit, parameter change, etc.) and retain the same map extent after each update, there are two options:

  • Update function – updates the screen, after first rebuilding a cache.
  • Repaint function - updates the screen, but if there is something in cache, the cache will be used to repaint the screen.

The use of the term "cache" here means a double-buffer for the output.
