Hi Mike,

i see that many gis/map applications supports a day/night effect. Do you have any idea how this can be achieved (using some filters etc, i dont believe that the loop for all the areas/lines/points and change the color).

I am searching on the google and so far i cant find anything.

Thanks in advance.

    They probably just change the default drawing style for some feature types and background color. You can do this with the SDK using the GM_SetBackgroundColor function and the GM_SetAreaFeatureClassDrawStyle, GM_SetLineFeatureClassDrawStyle, and GM_SetPointFeatureClassDrawStyle functions.

    Let me know if I can be of further assistance.

    Thanks,

    Mike
