- globalmapper.GetPixelColor(GM_LayerHandle_t32 aLayer, sint32 aRow, sint32 aCol) GM_Error_t32, GM_Color_t[source]¶
Retrieves the color at a given pixel location from the provided raster layer. If the layer does not contain a valid color value at the provided pixel location (i.e. it is a “no data” or transparent value), GM_Error_NoDataAtLocation will be returned.
- Parameters
aLayer (GM_LayerHandle_t32) – Layer to get color from
aRow (sint32) – Y coord of pixel (0 is topmost)
aCol (sint32) – X coord of pixel (0 is leftmost)
