- globalmapper.SetRasterDisplayOptions(GM_LayerHandle_t32 aLayer, GM_RasterDisplayOptions_t aOptions) GM_Error_t32
-
Sets the options to use when displaying the given raster layer. This includes things like the translucency and transparency (if any) of the layer, the color intensity of the layer, and whether or not to crop the collar of the layer.
Typically you will want to first call the GetRasterDisplayOptions function for a layer to retrieve the current display options, then modify the options that you want to change, then call SetRasterDisplayOptions to change the options. This will prevent you from inadvertently changing an option that you didn’t mean to change.
- Parameters:
-
aLayer (GM_LayerHandle_t32) – layer to set options for
aOptions (GM_RasterDisplayOptions_t) – display options for raster layer
- Returns:
-
Error Code
- Return type:
-
GM_Error_t32
Example
The following is an example of SetRasterDisplayOptions.:
