GM_SetRasterDisplayOptions |
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'll want to first call the GM_GetRasterDisplayOptions function for a layer to retrieve the current display options, then modify the options that you want to change, then call GM_SetRasterDisplayOptions to change the options. This will prevent you from inadvertently changing an option that you didn't mean to change.
